Download official Samsung Galaxy S2 firmware

1001

Can’t wait for official Samsung Galaxy S II firmware release from Samsung KIES? Or keep getting no update from your phone Software update? If you are a risk taker and wish to stay ahead of other people, you can always download latest official Samsung Galaxy S2 firmware and install on your SGS2. Most of the leaked official firmwares are for other region and not available on your region. But that does not stop those risk takers to try them out. How about you? Willing to take the risk and install the latest and greatest firmware on your Samsung Galaxy S2?

XWKDD, XWKE1, XWKE2, UHKE2, XWKE8, XWKE7, UHKE4, XXKE4, ZSKF1, XWKF1, XWKF3, ZSKF4, XXKF2, JPKF3, DCKF4, JPKG2, XWKG1, ZSKG2, XXKG2, XXKG5, UHKG7, JPKG5, DXKG4, JPKH1, DCKH2, DXKH2, DXKI2, XWKI4, XXKI3, CEKI2, ZSKI3, XXKI4, XWKI8, XWKJ1, JPKJ2, XWKJ2, XWKJ3, XWKK2, XWKL1, DXKL3, XILA2, XWLA4, XILA3, UHLB2, UHLPE, XXLPQ, ZSLPE, DXLP7, XWLP2, XXLPS, XWLP4, XWLP7, ZSLPG, DXLP9, XXLPW, XWLPD and XWLPF are the current official Samsung Galaxy S2 firmwares available to download at XDA Forum. Seriously, do we really need so much firmware releases? (I am coming from HTC HD2 which has much much lesser ROM upgrade) Maybe this is the spirit of Android platform ~ open source and always gets updated to the best. So far, we have Android 2.3.3, 2.3.4, 2.3.5 and 2.3.6 Gingerbread official firmware for Samsung Galaxy S2 GT-I9100. Android 4.0 Ice Cream Sandwich official firmware should come in Q2/Q3 2012.

    I am in Australia and purchased my phone from an online retailer – pretty sure it is a hong kong version.

    in About, I have a

    Android Version 2.3.3
    Baseband version I9100XXKG1.
    Build number GINGERBREAD.ZSKG2

    i want to upgrade to Android 2.3.4 to see if it fixes my poor battery performance, as I have read it can have an effect. However, I have no idea whatsoever which i should flash firmware too, or whether that matters or not. i am a complete noob to the android platform….

    any guidance would be appreciated!

    Hi Jayce

    I have installed XXKG5 without any issues. Everything runs well except the Kies Air. Everytime I want to access it from the website, it crashed the phone.

    Error message on the phone:
    The application Kies air (process com.samsung.swift.app.kiesair) has stopped unexpectedly. Please try again.

    Do you know how to resolve this?

    Thanks

    • http://www.jayceooi.com Jayce

      Sorry, no idea.

  • jjstephen

    Do we need to upgrade the current SG2 XWKF1?

    If i want to upgrade it to ver.2.3.4, which version of firmware i need to use?

    • http://www.jayceooi.com Jayce

      No, unless you want to. I am using XXKG5 (2.3.4). You can try it if you want.

      • jjstephen

        I found there are so many versions on samfirmware. Which one you can recommend?
        Is it ok go with the latest and it has European and Asian? Quite confusing. Please advise.

        Appreciate your kind assistance.

        • http://www.jayceooi.com Jayce

          I tested KG5 only. Don’t know other firmware okay or not. You need to try them yourself. Personally, I prefer custom firmware. ;)

  • nancy

    hi
    I am from jordan
    can you help me with an updated firmware 2.3.4 for my SGS II with full arabic support
    big thanks for your time

    • http://www.jayceooi.com Jayce

      As far as I know, there is no Android 2.3.4 Arabic firmware yet. JPKH1 is still based on Android 2.3.3.

    • Fahdsbs

      nancy just upgrade to any custom android(exynos,sensation,villain) 2.3.4 and download keyboard app from market which allows u to change language and type arabic…it worked for me using exynos v5 android 2.3.4…

      • nancy

        thankx
        i will try
        but i hope if the rom is official
        to have full arabic updated rom for my SGS II

        • fahdsbs

          My dear i think u should keep yo original firmware and wait for official firmware update for middle east region that will support full arabic coz the other’s dont support full arabic only typing is ok…..

  • DM21

    Hi Jayce,

    I’m from Philippines.

    My GS2 kernel version is 2.6.35.7-I900XWKF1-CL265340.. which firmware do you recommend for upgrade?

    In case, would it void the warranty?

    • http://www.jayceooi.com Jayce

      There should be a new firmware update for KF1 (at least for Malaysia) through Samsung Kies. Personally, I prefer XXKG5 if you want to install other region firmware. Yes, it might void the warranty but you can always revert back to stock firmware.

      • DM21

        Thanks for the response. If in case I decided to install the KG5 should I just follow the video mentioned above? What’s the difference between KF1 and KG5 in terms of features and functionality?

        Can you also provide the steps to revert to stock firmware?

        • http://www.jayceooi.com Jayce

          There is no changes log from Samsung between these 2 firmwares. But 1 thing that I know – battery life is better on KG5. ;)

          http://www.jayceooi.com/2011/08/14/how-to-restore-stock-firmware-on-samsung-galaxy-s2-video/

          • DM21

            I checked Kies and there’s an available update. KH1. Have you tested KH1? Im not sure though if it is already 2.3.4.

            • http://www.jayceooi.com Jayce

              I upgraded to DXKH2. It is still Android 2.3.3. But added Southeast Asia Languages.

              • DM21

                There are to links for the KH3.

                This package has: PDA: XXKH3| Modem/phone: XXKH3| CSC: OXAKH3.
                Download: http://www.multiupload.com/P92D3CE95I

                XXKH3 Stock Kernel: http://www.multiupload.com/C4DRUIJTLL
                Password: intratech@XDA

                Should I download both?

                I’m not sure if you have tested the KH3 but is it the latest compared to KG5?

                • http://www.jayceooi.com Jayce

                  Use the first one will do. The 2nd one is kernel. I did not try KH3 because it is Frankenstein Firmware.

                  • tarorod

                    @Jayce – just curious, what’s with Frankenstein Firmware?

                    • http://www.jayceooi.com Jayce

                      It is a mixed of different CSC, modem and leaked firmware packages. Not official.

        • http://- sham

            @sham, are you from philippines also?

            • http://- sham

              tarorod – no I’m from Malaysia…

  • DM21

    yep, it is still 2.3.3. Is there a possibility to upgrade to 2.3.4 without root-ing the device?

    • http://www.jayceooi.com Jayce

      You don’t need to root to install Android 2.3.4 if install the firmware through Odin.

  • Manuel

    Which Custom ROM IS suitable or can be used for baseband versiuon = I9100BGKF1 and kernel version = 2.6.35.7 -I9100BGKF5-CL342890 root@DELL105#2

    • http://www.jayceooi.com Jayce

      You should be able to try any firmware if your phone is factory unlocked.

      • Manuel

        I have only three days with him. It is unlocked, company Movistar (Spain).
        Kies updated to this version.
        Sorry about the translation.

  • Dylan

    hi, I m using KF1 nw, am hving prob with certain games. games suddenly shut off half way thru. will upgrading to KG5 helps???

    • http://www.jayceooi.com Jayce

      Hmm… It might be the games issue itself. Anyway, you can try to upgrade to latest firmware with Samsung Kies – DXKH2. See that improve it or not. Or try KG5 if you want. ;)

  • Allen

    any big different between DXKH2 and XXKG5?

    • http://www.jayceooi.com Jayce

      http://www.jayceooi.com/2011/09/03/new-firmware-upgrade-for-samsung-galaxy-s2-xwkf1/
      XXKG5 is Europe region firmware and it is based on Android 2.3.4.

      • Allen

        heard from some forumer, anything that flash with Odin eventually void the phone warranty. is that true? If yes how do I revert back?

        • http://www.jayceooi.com Jayce

          Yes, install custom firmware might void warranty. But you can revert back anytime you want. :)

          Any help that if I flash it with DXKH2 now?

          • http://www.jayceooi.com Jayce

            What help do you need?

            • Allen

              I am referring to does it help if I am flashing my current XXKG5 to DXKH2 to avoid the warranty void?

              • http://www.jayceooi.com Jayce

                Yes, and no need to worry much about warranty issue. Some people able to claim warranty even with custom firmware and rooted.

                • Allen

                  So I can direct flash my current XXKG5 to DXKH2 using Odin?

                  • Allen

                    or should I use Kies?

                  • http://www.jayceooi.com Jayce

                    Yes with Odin. You can’t use Kies because KG5 is not Malaysia firmware.

                    • Allen

                      so I suppose to use this one to flash?

    @Allen: Yes.

    • Allen

      Hi Jayce, I do face some problem after I flash my XXKG5 to DXKH2 using odin. Couple of funciton in my phone is not working. It gives error (e.g: phone contact, voice search , etc)

      • http://www.jayceooi.com Jayce

        You might want to wipe data and cache since XXKG5 to DXKH2 is not official path.

        • Allen

          it keep giving me the process android process.acore has stopped unexpectedly. Please try again”

          How to wipe data and cache?

          • http://www.jayceooi.com Jayce

            Note – this will delete all your apps and data = factory reset.

            Press and hold down Volume Up + Home + Power buttons at the same time.
            Release all buttons when you see SGS2 Logo.
            ClockworkMod Recovery will be loaded then.
            Select wipe data/factory reset.
            Then select Yes — delete all user data.
            Select wipe cache partition.
            Then select Yes — Wipe Cache.

            • Allen

              then do i need to flash again with DXKH2 after factory reset?

              • http://www.jayceooi.com Jayce

                No.

                • Allen

                  ok manage to get the phone work without error now. Really thanks alot. But then I found out that DXKH2 not as user friendly as XXKG5 especially on phone contacts

                  • Allen

                    what is the latest official version for now after XXKG5?

                    • http://www.jayceooi.com Jayce

                      It should be XXKH3 I think.

    Hi jayce!
    I recently bought sgs2 from Thailand it boxed with their thai telco carrier AIS.Seened to have problem surfing the web [very slow] .Is it locked to their carrier or is there a problem with their=the wifi firmware…Help please ?????I m using it in Malaysia with DIGI DATA PACKAGE….wHAT SHOULD I DO???
    tHANKS/REGARDS

    • http://www.jayceooi.com Jayce

      Which firmware are you using now? If can, try to use your DiGi on other smartphone. Make sure that it is not DiGi that causing the slowness. :P

  • james k

    Hi jayce,
    thanks for response.Hav tried yr suggestion by switching to my apple 3gs with Digi.
    On airplane mode with Wifi its super fast.
    Switching back toSGS2 with Digi on data plan+Wifi , it becomes
    sluggish…but on Digi plan with Wifi off it became super fast…
    Is the SSG2 android system designed to work with telco companies ? That means
    when surfing the web ?
    Hve read in ine SGS2 forums the Wifi connections can be really useless and crappy !!!!.My house Wifi is Unifly Vip 10 and yet its still darn slow ???Look forward to yr advise..Thanks/regs

    • http://www.jayceooi.com Jayce

      Sorry, I am a bit confuse. Is the Wi-Fi connection slow or 3G?
      SGS2 can be locked to 1 telco. But you can unlock it.

  • James K

    Working on the Wifi excluding the DIGI data plan in the SGS2 , the wifi connection is too slow and can just hang ! When Digi is on plus Wifi it still slow in connection…
    If the SGS2 is locked by telco [a possibility] how do we unlock it or how to verify its locked?
    Please advise…..
    Many thanks and regards for your kind effort to assist us newbies….

    Hi Jayce, have you tried KH2 2.3.4 for galaxy s2?

    here’s what I found in samfirmware.

    Also, there’s KH3 available as well.

    2) european languages package

                    • http://www.jayceooi.com Jayce

  • peterloyola

    hi jay
    i am having the indian version sgs2 xxkf3 ddkf3 gingerbread 2.3.3 and i updated with xwkh4 xxkh3 gingerbread 2.3.4 now i want to go back to my previous version.
    i have installed the previous version with odin but the device rebooted automatically several times without non stop so again i installed 2.3.4 now the device is ok.
    how could it be rectified for the previous version?
    thank you

    • http://www.jayceooi.com Jayce

      You need to wipe data and cache.

  • peterloyola

    Hi
    Jayce
    I need the tutorial to wipe data and cache.could you please?
    Thank you

  • mohammad

    dear brother
    first i want to thank you for your knowledge and your supporting
    second i just bought sgs2 before 3 days from (KUWAIT)
    i noticed that battery goes crazy down and i want to upgrade it
    i have xxkf1 .. im looking for any thing new and in same time can read and write arabic..
    third .. can i flash my mobile with htc official rom ??

    • http://www.jayceooi.com Jayce

      JPKH1 is one of Arabic firmwares. You can try it if you want.
      No, you cannot flash HTC ROM on Samsung phone.

  • Phenomenon

    Jayce,

    Thanks for your informant webpage.

    I’ve just got a GS2 in Malaysia. I’ve some problems and appreciate if you can guid me how to resolve.
    First is the internet connection via WiFi, that while I’m connected to my router with full signal, I can connect to any website very difiicult(may be 1 or time through 10 trial). My phone details is :
    Model No: GT-I9100
    Android Ver. : 2.3.3
    Baseband Ver. : I9100DXKF1
    kernel Ver. : 2.6.35.7-I9100XWKF1-CL265340, root@DELL106 #2
    Build No. : GINGERBREAD.XWKF1

    I heared that my firmware is an old version and it might be because of that. What is your idea?

    By the way I can see the websites in Persian language(persian or arabic fonts) properly.

    Considering above issues do you recommend a new software to install?
    if yes please reference me where can get and how to install as i m a newcommer to smart phones wolrd.

    Many thanks

    • http://www.jayceooi.com Jayce

      You can try to install Arabic JPKH1 firmware. But I am not sure it will help to solve your issue or not because I did not try it. ;)

      • Phenomenon

        Do you think that my internet connection problem is related to old version of ROM or the root is somewhere else?

        What is the most optimum ROM for GS2 with and without respect the language issue?

        • http://www.jayceooi.com Jayce

          Nope, I don’t have issue with Wi-Fi connection on XWKF1 firmware.
          XXKI3 is the latest one.

          • Phenomenon

            So do you guess any reason for that fault?
            I got this error once the mobile couldnt connect :

            “Data connectivity problem
            The server failed to communicate.
            Try again later”

            Does it show something?

            The router authentication is WPA2-PSK

            • http://www.jayceooi.com Jayce

              Do you get this issue on every website? Or just one?

              • Phenomenon

                I tried different websites. in 10 trials may be 1 or 2 or sometimes none become successfull.

                I also did a test by putting a galaxy plus beside mine and sitting close to router. the other phone could open all the webpages very quickly while mine was turning around to show the error.

                even once it could connect the page was loading very faster in other mobile than mine, while it suppose to be converse!(since mine is supperior)

                I wonder is it a software or hardware issue!

                • http://www.jayceooi.com Jayce

                  If you still have this kind of issue on other firmware, then it is hardware issue…

  • Phenomenon

    Sorry to modify :

    By the way I can NOT see the websites in Persian language(persian or arabic fonts) properly.

  • http://- sham

    jayce… why when i connect my GS2 at samsung kies in firmware information show S/W version in your phone is not an official version. Firmware upgrade of unofficial S/W version is not supported…. TQ

    Hi. I rooted my s2 with odin and superoneclick and then installed stock firmware. I need to send my phone to samsung. I also reset the counter with usb jig. I am assuming my phone is still rooted right. Will I have to unroot the phone? Will I have to install insecure kernel first to unroot or can I do it with stock firmware? Thanks in advance.

    what is the new fimware for the samsung galaxy s2?
    please give my a download link

      I just updated through samsung kies after restoring using Jayce’s video.

      Use the link in the post to download. Lowest is the latest.

  • Adam

    What is the difference between kernel and firmware?

    • http://www.jayceooi.com Jayce

      Firmware is like the operating system. Kernel is the main component of the OS.

  • SuperBatman

    Hey, just wanna know.. is this rooting or just a firmware upgrade? sorry-i’m a rook-

    • http://www.jayceooi.com Jayce

      This is firmware. Nothing to do with rooting.

  • Alex

    Dear jayce
    I bought samsung galaxy sII , and i need firmware have many language like :
    portuguese, english , chinese , arabic .
    any idea if have firmware include all this languages .
    thank you

    • http://www.jayceooi.com Jayce

      Official firmware sure don’t have these region languages in one. You can try to find a custom firmware in XDA. I also don’t know…

  • DM21

    Hi Jayce,

    If I root my phone, then I plan to restore it do I still need the usbjig or is it ok if I don’t use one?

    • http://www.jayceooi.com Jayce

      Not needed, unless you want to clear the custom flash counter.

      • DM21

        what’s the purpose of custom flash counter?

        • http://www.jayceooi.com Jayce

          For Samsung use only. To find out you are a naughty boy or not by playing with custom firmware / kernel. :P

          • DM21

            hahaha! i read an article regarding the use of usbjig to reset the custom flash counter as a route not to void the warranty.. but somebody said that there’s a hidden folder that also counts how many times you clear/reset the custom flash counter. not sure if it’s true. And also mentioned that someone is working on it now (Chainfire / XDA).

            Any thoughts?

            • http://www.jayceooi.com Jayce

              Yeah… I also read there is a 2nd counter. Who care? From what I heard, Samsung still give warranty to those with custom firmware. :)

              • DM21

                hehe! good to know.. but I’m waiting for the CM7 stable firmware.. not sure when is the release date though.. hehe!!

                As an alternative can you recommend custom firmware to use? where can i get/buy usbjig btw?

    Hi Jayce, im from Malaysia. I bought by SGS2 from Electric outlet(Senheng). Last month i install firmware version KH2(firmware from xda official firmware) on my Samsung S2, and upgrade by Kies to KI2.

    Information from KIES , Current firmware : PDA:KI2 PHONE:KI1 CSC:KH1(GLB).

    My question is, if i want to claim warranty for my phone. Do you think this version (GLB) can be claim at Malaysia First Mobile Group? I search on SAMFIRMWARE website, it show GLB is for Philippines.

    Thanks for your help!

    Few days i connect my Galaxy S2 to the latest version of Kies and Update was available for 2.3.4. Today i had time to update and connected to Kies and its now not showing the update.

    Ive uninstalled Kies and downloaded from Samsung latest version but the update still doesn’t show tied disconnecting again and again but no luck.

    What could i do?

    Also if i update from your site would i lose all my settings, I have SPB 3D Shell installed would i lose all the settings and folders created.

    Many Thanks,

    • http://www.jayceooi.com Jayce

      There is wipe and non-wipe version. Depend which one that you install.
      Always make a backup first before install new firmware.

      Consult Samsung Support if you want to upgrade through official way. :)

    hi jayce… u think can Android Honeycamb install to SGS2?

      Nope. But Android 4.0 Ice Cream Sandwich will. ;)

      Of course is ICS. It will be announced tomorrow.

        Ok but cant u answer 1 simple Question does flashing void warranty??

        • http://www.jayceooi.com Jayce

          Flashing own country official firmware does not void warranty. Others yes…

          • addy

            but what for example i live in india and Flash to Official Latest Firmware by Samsung (not Custom ROm) available in another country will this also Void warranty???

            • http://www.jayceooi.com Jayce

              Samsung India has the right to reject because you did not upgrade firmware through official way ~ Samsung Kies.

              No worry, just restore back to your original stock firmware will do if you want to claim warranty.

    Hi Jayce,

    I am from Malaysia. I super duper stupid ~ went to update Android 2.3.4 with GT-I9100_XEU_I9100XWKH4_I9100XXKH3_I9100XEUKD1. after done, i realize that it might void my warranty and some how is not my region firmware. so i would like to return to my original firmware version. But i’m forgotten the original firmware code. is XW or DX or others for Malaysia. i just remember that at the back show (xME). do you have any idea that Samsung GS2 in Malaysia should use which official firmware?
    Please advise. Appreciate that :)

    • http://www.jayceooi.com Jayce

      These are Malaysia official firmware – XWKF1, DXKH2 and DXKI2.

      • Renee

        if i need to refresh back Malaysia official firmware – XWKF1, DXKH2 and DXKI2.

    using odin is this OKAY? will my apps be remove? or whats is the best firmware for my s2.

    thanks in advance

    • http://www.jayceooi.com Jayce

      Yes, as long as you are using I9100. Apps should be intact. But no harm to make a backup first. Best firmware is depended on each person needs.

      • drake

        thanks a lot jayce.

        • drake

          Hi jayce

          I successfully updated my firmware to JPKJ2 and now im planning to root it. Can you please tell me what to do and how to root my SGS2. because Im confuse in what insecure kernel I will use.

          thanks a lot.

          • http://www.jayceooi.com Jayce

            No CF-Root for JPKJ2 yet. Need to wait or you can try the nearest one…

            • drake

              thanks again for your fast reply jayce. i think ill just wait for the cf-root f JPKJ2

  • Danny

    Hi Jayce,

    I recently bought a Samsung Galaxy S2 in China only to find out later that it had been flashed with a firmware that contained loads of chinese apps that I couldnt delete. I brought it back to the place and asked them to remove it and upload the default stock firmware which they said they did. The only problem is that when i use the samsung kies software it says it cannot update the phone because it the firmware is not official.

    Your instructions seem pretty easy to follow so I was thinking about flashing it myself. I was just wondering what stock firmware would be the best to install as I live in China but I am not Chinese (Irish)? If I install an Irish version will it work in China and allow me to update the phone using Kies?

    Also. Is the yellow triangle when you turn on the phone the only disadvantage of not having using the USB jig as I think this will be hard for me to get?

    Looking forward to your response.

    Thanks

    • http://www.jayceooi.com Jayce

      Sorry to inform that your China SGS2 cannot use any international SGS2 firmware / kernel. You can only use China SGS2 firmware.

      • Danny

        Thanks for the quick reply Jayce.

        I forgot to mention that I bought the SGS2 in a phone market and they said it was brought in from Vietnam. the version details are as follows:

        Baseband version: I9100XXKE4
        Kernel Version: 2.6.35.7-I9100ZSKF4-CL280225root@avad-server #22
        Build Number Gingerbread.ZSKF4

        • http://www.jayceooi.com Jayce

          Lucky you. You can install any official firmware at XDA since you are using international SGS2.
          Yes, you can upgrade firmware through Samsung Kies if you are using official firmware.
          Install official firmware won’t give you yellow triangle, no worry. And it should be easy to get USB Jig in China. Lot of electronic stuffs come from China nowadays.

          • Danny

            Thank you very much.

            Can you recommend a version of the official firmware that I should install?

            What are the differences?

            • http://www.jayceooi.com Jayce

              You can try XXKI4 Europe firmware.

              Hard to know the differences because Samsung does not provide change logs between version. So you need to test them to find out…

              • Danny

                Hi Jayce,

                I have finally gotten around to updating my phone to the stock firmware so that I can update it with Kies. Do i need to update the Kernel also or just flash the firmware?

                I have not been able to find the USB jig. Will not having using this have any effect on the installation.

                Danny

                • http://www.jayceooi.com Jayce

                  You already have stock firmware. Why bother to install kernel or firmware again?

                  No USB Jig is fine unless you install custom firmware / kernel.

                  • Danny

                    I bought the phone in China as I explained and it had firmware installed on it with a lot of chinese apps that I could not delete. I asked them to remove them and the firmware they put on the phone was is the following:
                    Baseband version: I9100XXKE4
                    Kernel Version: 2.6.35.7-I9100ZSKF4-CL280225root@avad-server #22
                    Build Number Gingerbread.ZSKF4

                    When I try to update with Kies it says firmware not official so I am going to flash with XXKI4 as you suggested.

                    • http://www.jayceooi.com Jayce

                      Oh, I thought already install XXKI4 firmware.

                      Just install firmware will do. Kernel no need.

  • Prashanth

    Purchased Samsung Galaxy S2 Mobile in China (Now I am in INDIA). Version ZCKH2; Android Version: 2.3.4. I am unable to update the Software and many programs still displaying Chinese Language though the Language is changed to ENGLISH. Please provide solution.

  • osama

    Hello Mr. Jayce ,

    I have bought SGS2 recently here in Jordan … I would ask about the latest firmware of android version 2.3.4 supports Arabic language …
    Does installing 2.3.4 really fix Battery life fast draining issue and weak wifi signal of my device ?

    my phone info:
    Baseband version: I9100XXKF1
    Kernel version: 2.6.35.7-I9100JPKG@-CL342890 root@DELL104#2
    Build number: GINGERBREAD.JPKG2

    Thanks …

    • http://www.jayceooi.com Jayce

      Usually, latest firmware is better and has less issue. You need to try them yourself to find out. As for me, I am using XXKI4. Battery life is sure better than my stock firmware.

  • Wang

    May I know the latest kernel version for Malaysia S2? I mean official rom given by Samsung Malaysia. Thanks in advance.

  • Dale

    hi jayce!

    it me again, i want to flash a STOCK XXKI4 firmware.. remember that im now coming from checkrom revolutionHD..should i restore to my backup,the XWKF1 CF-root before i go to the stock XXKI4? tnx!

    • http://www.jayceooi.com Jayce

      You can install XXKI4 stock firmware directly. Do wipe data and cache.

      But why do you want to install XXKI4 stock firmware?

  • Dale

    dalviks not included? im facing battery issues.. i read at xda..that its good if your coming from STOCK XXKI4..before you proceed to checkromrevoHD.. what are your thoughts about it? tnx!

    • http://www.jayceooi.com Jayce

      Huh? Does it really matter which firmware you coming from (after you wipe data and cache of previous firmware)? I am coming from XXKI3 stock firmware. No battery issue.

  • Dale

    someone told me that.. going back to installing the stock firmware.. even i am now on checkromrevoHD.. i can simply flash the stock firmware and thats it? via odin right?

    • http://www.jayceooi.com Jayce

      Yes, just install it with Odin.

  • Dale

    I downloaded the firmware..and the kernel..how will i install the stock kernel for the XXKI4?

    • http://www.jayceooi.com Jayce

      The firmware includes kernel already. No need to install kernel separately again. Kernel installation is the same as firmware.

      • Dale

        do i need to wipe first my checkromrevoHD before i go with the installation of the stock firmware?

        • http://www.jayceooi.com Jayce

          I told you before already.

          • Dale

            oh sorry, my mistake. first i must wipe data and cache via CWM..after that il choose power off and then load odin by holding volume down + power + home key.. then flash the tar file?

            • http://www.jayceooi.com Jayce

              Yup…

              • Dale

                tnx! assuming i am on STOCK XXKI4..can i install the checkrom revoHD wihout rooting? how can i do that?

                • http://www.jayceooi.com Jayce

                  Install like the way you installed previously. Need CWM.

                  • Dale

                    ahh..so i need to root the stock by using the XX_XEO_KI4 right and then install checkrom via CWM. and oh the checkrom revoHD 2.0 is out with DK siyah kernel.. how can i install it?

                    • http://www.jayceooi.com Jayce

                      Same using CWM.

  • Dale

    assuming that im already on checkrom revolutionHD 1.0.. il use CWM to install the 2.0 version..do i need to wipe data/factory and cache? and how about the kernel(the Dark Knight Siyah kernel) how will i install that..they said it has major tweaks on battery life. tnx

    • http://www.jayceooi.com Jayce

      It should be non wipe version. So no need to wipe data and cache. I did not test v2 yet. If DK kernel does not come pre-installed, you can install it manually with KitchenPro.

      • Dale

        question again sir, can wipe also battery stats..does it improve my battery life? will it do harm to my phone? tnx!

        • http://www.jayceooi.com Jayce

          Sure. No idea. Some said yes, some no. Harm? Nope, if harm also on battery only.

          • Dale

            sir jayce, im about to flash a tar file..but the format is tar.md5? is that safe? before i only flashed .tar file..

            • http://www.jayceooi.com Jayce

              Yes, tar.md5 is fine.

              • Dale

                thank you sir!

  • Allen

    Hi Jayce

    I am currently running XXKG5. Any big different if upgrade to XXKI3/XXKI4?

    I notice that at xda page highlight that it comes with boot-loader? what does that mean? Can I just flush it from XXKG5 to the latest? btw latest official is XXKI3 or XXKI4?

    • http://www.jayceooi.com Jayce

      No idea about the different. No change logs…

      Latest official firmware has new bootloader that causing USB Jig cannot clean the custom binary counter. But no worry, firmware at XDA has the old bootloader. Yes, you can install from XXKG5. XXKI4 is newer.

  • Euds

    hi Jayce, nice help you have here, but just want to ask Question, we have the same BUILD the Stock (PDA: I9100XWKF1 PHONE:I9100DXKF1 CSC: I9100OLBKE5)just like on the video, and you change it to XXKG5,Firmware info:PDA:XXKG5,PHONE: XXKG5,Date: 27/07/2011,Android 2.3.4. is this the latest firmware??? pardon me but im a newbie ^^. .thanks a lot and hoping to hear from u soon

            • http://www.jayceooi.com Jayce

              If the router did not block that SGS2, then it is software issue. Try to factory reset that SGS2.

              • Euds

                thanks a lot jayce ill try to reset it then post what happen, again thanks a lot

                • Euds

                  another thing, do i have to Root my SGS2 even if i update it to XXKI4?

                  • http://www.jayceooi.com Jayce

                    Root or not root is totally up to you.

  • sivasudha

    HI Jayce, i had rooted my sgs2 to a custom kernel and then unroot it to samsung official firmware XWKF1. Now my phone reads Android version 2.3.3… Baseband version DXKI1…Kernel version 2.6.35.7-I9100XWKF1-CL265340root@DELL106#2 and Build number GINGERBREAD.XWKF1. Now i m facing a problem.. I wont able to import my contacts from Kies and the firmware update is also blanked off. whenever i try to restore, kies stopped working and the phone disconnected.

    Please help me to connect with kies.. for restoring contacts and firmware update

    • http://www.jayceooi.com Jayce

      Your baseband should be DXKF1 not DXKI1 for XWKF1 firmware. Did you wipe data and cache?
      Besides, I don’t use Samsung Kies to backup / restore as many said it is buggy and not working sometimes.

  • Tony UK

    Hello,

    Galaxy s2
    XXKG3

    I updated my galaxy s2 a few weeks ago with your instructions all went well, but now I’m facing issues
    With my battery, its fully charged without using the phone or any calls after an hour its drops to leSs then 80%.
    Please help should I re install the firmware?

    I’m not sure if I did a cache or data remove? Nor i know how to do it, would be able to guide me please.Also would that delete everything from my phone?

    Many Thanks,
    a

  • Tony UK

    Thanks for the reply.

    How do i do a cache and date clear anyway.

    will that sort my battery out? Or do i have to do a hard restore and then reinstall the 2.3.4?

    • http://www.jayceooi.com Jayce

      Wipe data = factory reset. No idea it will solve your battery issue or not.

      Hard restore?

  • Adam

    Thanks for quick reply, but Samsung Kies has failed dramatically on my computer, cannot seem to get phone to link up to it. thats why i found your article and explanation.

    I managed to put BOKG2 on phone using your instructions flawlessly, however now i want to know how far can i push this phone without losing any functionality? ( i.e. the latest firmware i should be able to run on this phone without a risk of bricking it or just breaking it :P ).

    Thanks alot

    • Adam

      PS. sorry for starting new thread. clicked on wrong button

    • http://www.jayceooi.com Jayce

      I don’t have a carrier branded SGS2. Not sure custom firmware will work on it or not. You need to ask others who has the same model as yours at XDA see.

      • Adam

        Just to clarify as i am unsure. how do you define a ‘branded’ SGS2.

        My contract provider is T-mobile however there is no specific branding on the phone itself stating its tmoble ( all i have is a Samsung written front and back).

        Is the branding guaranteed just by buying the phone through them?. or is it possible i have an unbranded phone which they merely distributed?.

        Is there a way to find this out?

        Thanks

        • http://www.jayceooi.com Jayce

          Based on your firmware BOKG2.

          Sorry, I don’t have much info about carrier branded SGS2. Maybe their hardware are just like others GT-I9100. So do ask others see.

          • Adam

            Im new to this whole aspect of meddling with phones, which forums would you recommend I use?.

    Hi jayce..

    It seems like xxki3 is stll not solving the bettery life. or is it just me. Compare it to my previous firmware which is dxki2, i think that version lasted longer. Any explanation? Thx =)

    • http://www.jayceooi.com Jayce

      How many day did you use XXKI3 firmware? You need several battery cycles to get accurate data.

      FYI, my phone with XXKI3 uses around 3% per hour standby with 3G data on.

      • Fander

        i dint even use it to sms.. about 3days i think. only switched on wifi. n i dint even surf the web. i just leave it idle.

  • Nuno Ribeiro

    Hi jayce..

    First of all, you are amazing… Thanks for all
    If I want to restore for my current stock rom which is XWKI4 and if I want to use USB JIG i need to flash the old bootloader. This old bootloader will be detected by Samsung? Or maybe I can restore the new bootloader after and it will not increase counters?

    Other issue: did you ever done a backup of your efs folder in order to be safe of losing your IMEI?

    Thx from Portugal :)

    • http://www.jayceooi.com Jayce

      The old bootloader can be detected by Samsung since XWKI4 is using new bootloader now. Install official kernel / firmware won’t increase binary counter.

      I did make EFS backup myself (just copy and paste, some said this method won’t restore well). And got several auto backups when install custom firmware too.

  • Ande

    Hi Jayce,

    i just flashed my phone today to the XXKI3 2.3.5 and it seems that the home screen is a little laggy when i switch between them. is that normal ? should i flash to a 2.3.4 ?

    Thanks for your time,

    Ande

    • http://www.jayceooi.com Jayce

      Mine also seem lag a little bit. You can try to factory reset to make it clean if you are okay to delete previous apps, data and settings.

      • Ande

        Yeh i tried all of those options but it still seems to be laggy. no idea wats going on. you would think 2.3.4 and 2.3.5 would be better but it doesnt seem to. it wasnt lagging with 2.3.3 tho

      Not a must if coming from previous Samsung firmware. But recommended as I always wipe data on new firmware to have a clean start.

      • DM21

        actually, my current firmware is KG5. so do i have to wipe everything? :)

        • http://www.jayceooi.com Jayce

          As I said, not a must.

  • http://www.hamed.ws Hamed

    Hi Jayce,

    How do i download this firmware?

    PDA:KJ2 / PHONE:KI4 / CSC:KJ1 (XSG)

    Thanks!

    • http://www.jayceooi.com Jayce

      Just download it from shared file hosting.

  • http://www.hamed.ws Hamed

    Dear Jayce

    I didn’t find it anywhere ? and it doesn’t update via Kies as well.

    • http://www.jayceooi.com Jayce

      If you can’t find it at XDA, then this firmware does not exist. You can’t update with Samsung Kies if it is not official firmware.

      • http://www.hamed.ws Hamed

        No I have internet problem and the firmware doesn’t go more than 50% during update via kies, it gives operation timed out error.

        Thanks

        • http://www.jayceooi.com Jayce

          Check with your Internet provider in this case then. ;)

    Thanks

    • http://www.jayceooi.com Jayce

      I don’t have US T-Mobile SGS2 to test. So can’t help much. Sorry…

  • maximo

    hi jayce..i have a rather noobish question..can i flash other region firmware into my malaysia galaxy s2? and another question is, which region official 2.3.5 do you prefer for me to flash?
    china or europe?

    • http://www.jayceooi.com Jayce

      Yes, I am using Europe XXKI4 firmware on my Malaysia SGS2 now.

      • maximo

        i would like to download the xwkj3 firmware..is the firmware only for certain operator or for sim free phone?

        • maximo

          and 1 more thing. to download the firmware from xda, which link should i choose? is it the one with the stock kernel or the one without?

          • http://www.jayceooi.com Jayce

            Without one.

        • http://www.jayceooi.com Jayce

          SIM free one.

  • sham

    Jayce : can i change my XXKI3 firmware to XXKI4 firmware on my Malaysia SGS2??? & my data will lost or not?

    • http://www.jayceooi.com Jayce

      Sure, why not? It should be non wipe version on XXKI4. But no harm to make a backup first.

  • toffee

    Jayce? I need your assistance. on KIES when i connect my SGS2, it said, YOUR DEVICE DOES NOT SUPPORT SOFTWARE UPGRADING VIA KIES. what does that mean?

    I9100XWKG1/I9100JVKG1/I9100XXKG1/I9100XWKG1 <– this is my current version.

    can you help me update this or is it possible to update it? thank you very much.

    • Rod

      I don’t get the letter code thing in the firmware page

    • http://www.jayceooi.com Jayce

      JVKG1 might be causing the issue since XWKG1 firmware does not have it.

      • toffee

        then what do i have to do next? how can i fix this?

        • http://www.jayceooi.com Jayce

          Restore back to your original stock firmware. Then upgrade it again with Samsung Kies.

  • toffee

    i dont know how to restore it back.

    actually, i had to replace my phone’s board because of the heating. which the service center recommended.

    im thinking of updating to a higher version but scared to flash it and void the waranty. im dunno!!!

    • http://www.jayceooi.com Jayce

      In this case, don’t do anything until you get a new motherboard from Samsung service center.

      • toffee

        the motherboard has already been changed and that’s what it is now.

        I9100XWKG1/I9100JVKG1/I9100XXKG1/I9100XWKG1 <– this is my current version.

        • http://www.jayceooi.com Jayce

          Since you got the replacement motherboard with this firmware, consult Samsung Support why it cannot be upgraded with Samsung Kies.

          • toffee

            ok. i guess there’s just no update here in the Philippines. Was just worried last time coz you said JVKG1 might be causing the issue since XWKG1 firmware does not have it.

            or probably im just confusing myself. or desperate about the upgrade.

  • MeHDi

    Hi Jayce;
    There is no Arabic Language in JPKI1?
    i Confused bro

    • http://www.jayceooi.com Jayce

      I did not test it personally. But this is Arabic firmware (based on the info that I got). Did you change the language in settings?

      • MeHDi

        Yes. But i didnt see any arabic language in language setting :-(

        Jayce; i downloaded darkyrom But When I Extract DOWNLOADED FILE sEE too Many Folder. What I Do Now?

        • http://www.jayceooi.com Jayce

          • mehdi

            how i can install this zip folder? by odin???

            • http://www.jayceooi.com Jayce

    • http://www.jayceooi.com Jayce

      Good. Just follow the installation guide then.

      • MeHDi

        Jayce;
        My Firmware version is JPKI1 2.3.4.
        i want to install Darky rom and i have to download my own cf-root file.
        there isnt any jpki1 cf-root file in your site.
        what should i do now?

        • http://www.jayceooi.com Jayce

          Use the nearest one.

          • MeHDi

            My firmware is JP-KI1.

            Which is nearest?

            JP_XSG_KG2 or JP_XSG_KG5?

            XX_OXA_KI3 or CE_XEN_KI2?

            • http://www.jayceooi.com Jayce

              Personally, I will select KI series.

              • MeHDi

                Then i select XX-OXA-KI3

  • Fander

    Jayce ,

    XXKI3 or XXKI4.. which is better?

    • http://www.jayceooi.com Jayce

      Both of them perform the same to me. I can’t find the different. XXKI4 is newer.

  • Fander

    ok .. cheers =)

    Hi, What is the best battery efficient modem/baseband/phone update you have tried that works well in Malaysian region? KI3, KI4, KH3, KG…??

    • http://www.jayceooi.com Jayce

      I don’t care much about modem. So no idea. FYI, I am using XXKI4 baseband now.

  • Sixth

    Good pm Sir.

    I am from Philippines, I decided to use your guide for flashing my SGSII

    And I have the following.
    Video of how to install firmware on samsung galaxy s2 with odin.
    Video of how to restore stock firmware on SGS2.
    GT-19100_XEO_I9100XXKI3_I9100OXAKi3_I9100XXKI3 <- Official right?
    GT-I9100_SIN_I9100DXKI12_19100OLCKH1_I9100DXKI1 <-Stock Rom, to revert?
    Kernel_I19100DXKI2 <- Same as above
    Odin
    Enough english to understand the non technical terms
    Enough courage to take the risk of flashing.
    And the following questions:
    1. With what i have, Basically I just follow your step by step instruction and the video and if all things remain constant, I will have no problems whatsoever?
    2. I'm new to this flashing game, when I want to revert back to the old firmware, with what i have above, would it suffice?

    What my phone says it is
    Baseband Version: I9100DXKI1
    Kernel version: 2.6.35.7-I9100DXKI2-CL564948 root@DELL129 #2
    Build number: Gingerbread.DxKI2
    Unrooted. Unlocked

  • Sixth

    Noted. I dont want custom roms, I just want official 2.3.5 from other Region. If it was not for the slow update record of samsung, I wouldn’t have to flash. Philippines is yet to get 2.3.4 thru Kies, Others are already on 2.3.6, and theyre talking of ICS. Will try tom, hopefully help my other friends using this phone too. Mabuhay!

    • http://www.jayceooi.com Jayce

      Personally, I did not notice any different between XXKI3 and XXKI4 official firmware.
      Yes, I9100 firmware update in SEA is slow and still stuck at Android 2.3.3. Same at Malaysia since we are using the same firmware in SEA.

      • Sixth

        wait so XXKI4 is the official firmware? I should stick to official, some guys here told me that I wont void my warranty if i use official Firmwares (even if from other regions). I just want that so called battery improvement, if if fails my expectations, im going to revert back to stock rom.

        • http://www.jayceooi.com Jayce

          XXKI4 is also official Europe firmware. Just I am using the custom ROM based on it.

          • Sixth

            OK, thanks for clarifying that up. Will now download XXKI4.

  • Kishore

    How to change the language in a Galaxy S2 to spanish (when this language is not included…)?

    Can you guide us to the best solution?

    Hi, I bought my Samsung Galaxy S II in China, and currently have the Chinese version of Gingerbread, which lacks many of the apps that the Americans version has. Is there somehow I can replace my present OS with the US gingerbread?

    • http://www.jayceooi.com Jayce

      Sorry, no. Their hardware are not the same.

  • mtd

    just to let you know the emerency calls only thing is because the phone I got (second hand!!) had its IMEI blocked in the UK because the previous owner declared it as LOST to the carrier and they blocked the IMEI. Thats a waste of money!!

    Thank you for your help

  • Jarzi

    HELP!

    Got a problem while trying to restock back into original firmware , using jayce’s tutorial video and forums. Guides were simple and I thought it’s easy thing to do. Previous Rom was Litening rom, not the latest version. Odin gets stuck while trying to write cache.img.. nothing happens and it doesn’t move. Do I dare to close the Odin. It has been like this for 2 hours now. Should not take this long.

    I have nordic region scandinavian phone (Finland) region phone, XXGK2.

    Is there a way to restore the firmware through Kies or should I try other firmware update? Or is this about Kernel, no?

  • Jarzi

    When i try to boot to the “ClockworkMod Recovery”

    All I get is a phone, triangle with exclamation point and a line to computer. Does this mean I have to do something with Kies?

    Is it perhaps stuck now because Odin tried to push a new firmware on top of old one?

    Because now I have to admit I did not reboot to the recovery mod in the first place.

    • http://www.jayceooi.com Jayce

      No.

      Maybe. What firmware did you install?

        This was first one I tried. Now update: Odin does not recognize the phoen connected afterI took out the battery for 30 minutes. But I still can get to download mode. Is there any chance to get to recovery mod anymore? to make a clean wipe. At least the counter is 0 in the custom binary. It says the installed binary one on my phone is Samsung official now.

        Yes, I ruled out the Kies now.

        • http://www.jayceooi.com Jayce

          Odin does not recognize your phone? This is bad. And you can’t load recovery mod if it is corrupted like your case. Try to install wipe version of firmware if you still can get Odin to work out.

            I will try this now and update of what happens..

          • Jarzi

            Odin finally failed, i dont know after how many hours after being just still and not moving. Factoryfs.img did not go through..

            It seems the it just doesn’t run the flashing on the phone now, just gettin stuck on a certain point. Also, getting to recovery mod doesn’t work…

            This wipe version of firmware went furthest on it’s installing than the others though..

            • Jarzi

              Okay Jayce, so…

              The installing of wipe , stock firmware was unsuccessfull.. so.. I just gave up.Finally.

              update:

              I took the phone today to a warranty repair. They said they will wipe the software and make a clean reset on the phone. It should be back in my pocket before christmas!

              • http://www.jayceooi.com Jayce

    - Tried o boot to CWM recovery and doesn’t work
    – Download mode works but when i try to flash through Odin, it just stops transferring on first img-file
    -Kies is shut down when i use Odin.

    Feels like i bricked my phone totally. Any suggestions? One-Click Unbrick program I also tried.. but it failed.

  • Bryan

    Hi Jayce, I have a samsung galaxy S2 with baseband DXKH2 does that mean that if I want to upgrade to a higher version, I have to get the firmware that is the same as my baseband version which is DXKH2?

    • http://www.jayceooi.com Jayce

      Nope, you can install any firmware that developed for I9100.

      • Tyler

        the part i don’t understand is: why is there a list of supported basebands, if we can just go to xda and get any of the firmwares for our i9100s? Which one should i get: i just want to flash to 2.3.6

        • http://www.jayceooi.com Jayce

          Ask Samsung why there are so many firmware. I also don’t know. Just find Android 2.3.6 firmware to install.

  • Tyler

    where can I get 2.3.6 for UGKG2?

    • http://www.jayceooi.com Jayce

      As far as I know, I don’t think there is Android 2.3.6 firmware for UG region yet.

    Hi,

    I have recently rooted my phone. But one problem i noticed after rooting my phone is most of the apps in the market are not supported. I didnt load any custom ROM, But i rooted my phone by flashing with insecure kernel (Through ODIN ). and then used software to root it.

    My Kernel version is i9100XWKF3 (insecured kernel) im getting a yellow triangle during boot.
    Baseband version is i9100DDKE4
    Build number XWKF3
    Android version 2.3.3

    • http://www.jayceooi.com Jayce

      Yes, India SGS2 I9100 still stuck at Android 2.3.3 just like my country, Malaysia. Why? Ask Samsung, I also don’t know.

  • Lim A L

    Hi Jayce, I’ve just upgraded my sgs2 from 2.3.3 to 2.3.6. Now my kernel is XWKK2. Seem working fine. I am planning to root it, does this means I’ve to use XW_XEN_KK2 to root it ? Many thanks in advance. Lim

    • Lim A L

      Forgot to mention, previous Kernel version is DXKI2. After upgrade is XWKK2.

    • http://www.jayceooi.com Jayce

      Yes, XW_XEN_KK2 is the one.

    Hi Jayce,
    I upgraded my firmware from 2.3.3. to 2.3.6 and rooted it last night with XW_XEN_KK2. I am contemplating to install litening rom. In the event if I decided to revert all back to stock are these the only two I found in XDA needed to flash back ? My stock version is DXKI2

    Hi Jayce,

    I tried to upgrade fm from 2.3.3 to 2.3.6 but failed.
    This is the message I got during upgrade with odin

    Enter CS for MD5..
    Check MD5.. Do not unplug the cable..
    Please wait..
    GT-I9100_XEN_I9100XWKK2_I9100XENKJ1_I9100XXKI4.tar.md5 is valid.
    Checking MD5 finished Sucessfully..
    Leave CS..
    All threads completed. (succeed 0 / failed 0)

    My present kernel version is 2.6.35.7-I9100DXKH2-CL483911 root@DELL138#2
    built version: gingerbread.DXKH2

    did I something wrong? I used you provided link for SW DL
    My S2 is still working on 2.3.3 w/o problems

    rgds, Erwin

    • http://www.jayceooi.com Jayce

      Not sure what went wrong. Try other firmware see.

      • Erwin Stolz

        read on another thread that maybe my S2 isn’t recognized by odin, however if I connect my phone via usb connection I can see it on my computer and can copy/move files
        any thoughts?
        any link for another 2.3.6 firmware?
        thanks

        br, Erwin

        • http://www.jayceooi.com Jayce

          Do you have Samsung Kies on your Windows? Odin needs to use its USB driver.

          • Erwin Stolz

            yes, I do. I can use Kies w/o problems on my computer

            thanks for your patience

            erwin

            • http://www.jayceooi.com Jayce

              Hmm… Anything different between yours and mine in the installation video?

              • Erwin Stolz

                SUCCEED!!

                Your hint regarding Kies driver was the point.
                When I mentioned that I use Kies, it was only Kies Air.
                So I DL Kies from your link, installed on my computer, running the procedure as in you video, viola! that’s it

                I’m running now 2.3.6 and its working nicely, so far.

                Thanks a lot for your help, very much appreciated

                  1. Yes. However, you might need to factory reset if face force close issue.

                  2. No idea. No change log from Samsung.

                  3. Usually no. Unless that firmware is a wipe version.

  • Joe Small

    Hi there, I’m on Vodafone Australia, and I was wondering what ROM I should be flashing? There seem to be three different options, and I don’t know how I should pick
    Thank you so much for any help

    • http://www.jayceooi.com Jayce

      Hi Joe, what do you plan to do with new ROM? You can flash any I9100 firmware on your SGS2 I9100.

      • Joe Small

        The reason I’m doing it is because I was trying to install MIUI, but it’s stuck trying to boot up! So I did some research, and thought that the best way would be to wipe it and install new firmware

        • http://www.jayceooi.com Jayce

          You have CWM installed, right? Wipe data and cache. Then install MIUI ROM again.

          • Joe Small

            Thank you so much for all your help!

            • Joe Small

              Oh sorry, so just to confirm, I would need to “wipe data/factory reset” and “wipe cache partition”?

              • http://www.jayceooi.com Jayce

                Yes Joe.

  • Joe Small

    Incredibly, I didn’t even need to reinstall MIUI! It worked as soon as I wiped those two things

  • David Wilson

    Hi Jayce, just wondering if you could give me some advice please mate? I’ve just received a SGSII with a custom ICS rom installed which is very buggy and I’m not happy with it at all. I want to revert back to stock Samsung firmware,which I can do thanks to your very helpful (and easy to follow) video and instructions, but I’m not sure which firmware version to get. I live in Australia and was hoping to get a version of Gingerbread 2.3.5 or 6 hopefully without any carrier bloatware. I was doing some research on the XDA Developers forum and came across a firmware version XWKK2 which I think is a generic Australian firmware but not too sure. Any advice on the subject would be greatly appreciated. Thanks in advance, and keep up the great work.

    • http://www.jayceooi.com Jayce

      Personally, I did not try XSA Australia XWKK2 firmware. So no idea. But I am using XWKK2 custom ROM now (based on Netherlands firmware).

      • David Wilson

        Thanks for the advice Jayce. I flashed the XWKK2 firmware without any problems and it works really well, except that the email isn’t working. As soon as I turn the phone on, an error message appears saying Unfortunately Email has stopped working com.android.email and all I can do is force close it. Any ideas or suggestions on what could be causing it/what I can do to fix it? I have re-flashed the firmware to try and fix the problem, but still the same thing. Thanks Jayce.

    Hi Jayce,
    I had downloaded the new firware for my samsung galaxy s2 yesterday to give it a shot. In short, it sucked. Lost of bugs. So I had tried to revert back to the old firmware by using Odin. Halfway through the installation, my usb had unplugged and I turned my phone into a brick. Do you think my warranty is void because of this? Im sending it in for repair, although im unsure if Im able to get it fixed.

    • http://www.jayceooi.com Jayce

      No issue if you install official firmware. Anyway, can you still able to load Odin download mode?

      • Derek

        No, I cant even turn on the phone. Its a complete brick. Odin works, but the phone cant be set to download mode or reset mode.

  • Derek

    Also, when I said “i had downloaded the new firmware for my samsung” i ment the firmware that was not yet released to the public. xx8 and xxA.

    • http://www.jayceooi.com Jayce

      So it is not official firmware. Try your luck at Samsung Service Center then. ;)

      I am using custom ROM based on XWKK5 firmware. Battery life is good for me.
      You can install any I9100 firmware on your SGS2 I9100.

  • ong ting hou

    Hi

    I just bought Samsung Galaxy S2 in US yesterday. I will be leaving to India in one week. I will unlock my Samsung Galaxy S2 while in India so that I can use local SIM card. In that case, can I get a local SIM card with data plan. Also, will the resync to corporate email – does it have to be done with my IT help or I can it myself.

    • http://www.jayceooi.com Jayce

      Sorry, I have no idea as I don’t have US SGS2 and don’t live in India. And don’t use corporate email now too.

    Hi jayce!
    I would like your help on the firmware I should download. I’m for JPKJ2 and I bought my phone here in Qatar. In the site http://forum.xda-developers.com/showthread.php?t=1075278, JPKJ2 has 2-3 links depending on which region I bought the phone but I’m troubled between the 2-3 links.

    1st link: OJP (ABS, AFG, BTC, EGY, JED, KSA, LEV, MAT, MED, MID, MMC, MWD, OTU, PAK, THR):http://www.multiupload.com/CM6XON5S36

    2nd: XSG (UAE): http://www.multiupload.com/UQMCDCD9LD

    3rd: JPKJ2 Stock Kernel:http://www.multiupload.com/DUNKIR221F

    Should I download all? Or choose between the 1st and 2nd link, and the 3rd link I still must download it? My region is in Qatar. I rooted my phone but I erased my back up and I can’t unroot anymore. Thank you very much.

    • http://www.jayceooi.com Jayce

      Sorry Rob, I am not sure which firmware is for Qatar (1st or 2nd). The 3rd one is kernel (not firmware).

      • Rob

        Hi Jayce! Thanks for the reply.

        I checked the outside of the box of my SGS 2.. It has the product code GT I9100LKAXSG, I think I’m for UAE. However the link for the firmware I still can’t download it for a couple of days now. Is it ok if I’m going to download an Official Firmware from samfirmware.com? Do you know if they’re the same? TIA

        • Rob

          (Added inquiry)
          By the way Jayce, I have an Odin program but it’s 1.83 in which I have used in rooting my phone. Should I download the latest Odin 1.85 or no need to download it anymore. I also have the secure kernel (original- which I used before to remove the triangle after flashing an insecure kernel) from the time I rooted my phone, so does that mean that I also don’t have to download the stock kernel? (because also the link for the stock kernel doesn’t work.
          If I download the official firmware (from samfirmware.com) and just flash it in the PDA, after that I should flash the stock kernel in the PDA section in the Odin program again? I’m sorry I’m just a noob hehe..

          • http://www.jayceooi.com Jayce

            I did not try Odin v1.83 before. No idea.

            Just flash firmware will do. Kernel is not needed unless you need to remove yellow triangle.

        • http://www.jayceooi.com Jayce

          They should be the same but I did not try SamFirmware.com firmware.

          • Rob

            I downloaded the new Odin with your link and follow your instructions. All is well now, I have flashed the stock firmware and saved a back up for the root. Thank you very much for your help. :)

    Hi, love your site, very helpful. I’m hoping you can help me further.

    I’ve been able to use my SGS2 with the local sim cards in the Philippines, UK, and Brazil. I’m now in Korea and when i bought a prepaid SIM from KT Olleh, my phone doesn’t have a network signal. Am I locked or something? Or should I change CSC? I have a multi-csc but it only includes nepal, sri lanka, indonesia, no korea. My phone’s details are below:

    android version: 2.3.6
    baseband: I9100DDKL1
    Kernel: 2.6.35.7-I9100DXKL3-CL814816ROOT@dell137 #2
    Build: gingerbread.xwkl1

    Thanks very much!

    • http://www.jayceooi.com Jayce

      Is KT Olleh using GSM?

      • dante

        I think so, GSM and WCDMA. I just noticed now, my phone’s network has my home network (GLOBE TELECOM), and written above that, SK TELECOM. So should I probably get a sim from SK? I asked at an SK store previously, they didn’t seem to have a SIM, and directed me towards KT (though my Korean guide doesn’t have quite a good grasp of english so there might be something lost in translation).

        thanks

        • http://www.jayceooi.com Jayce

          I have no idea then. CSC should not affect anything as I am using Europe CSC on Malaysia carrier now.

          Try to consult KT Olleh.

          • dante

            okay, thanks very much

  • http://fsgamers.org Dallas

    G’day Jayce.

    I have just rooted my Galaxy S2 and I would like to find the stock kernel for it before I try to upgrade and to get rid of the yellow triangle at boot. I just can’t seem to find it anywhere but on xda via mulitupload.com which is down. Where else would I be able to get it from? My carrier in Australia is Telstra.

    My phone specifications are:

    Model Number: GT-I9100T
    Android Version: 2.3.3
    Baseband I9100TDVKF2

    i had upgrade my i1900 to ICS 4.0.3 through kies..
    so far i’m not satisfy with it, blackout when playing game,apps get jam, easily overheating..etc.
    what should i do now..should i downgrade to 2.3.6 (my old version), or just wait for samsung to release a new stable version officially..
    ..fed up with my phone now…

  • Saduff

    Hi,

    I can’t connect my Galaxy S2 (GT-I9100) with Kies, so I’m thinking about upgrading my firmware to ICS with Odin.

    Android: 2.3.6
    PDA: XXKL1
    Phone: XXKL1
    CSC: OXAKL1

    I want to upgrade to ICS before rooting. Which ROM should I use from XDA?

    • http://www.jayceooi.com Jayce

      Any ICS firmware that you prefer.

      • Saduff

        OK, I think I’ll flash the XXLPQ XEU firmware. Do I need to replace Gingerbread bootloader also? I don’t want to mess with bootloader stuff since that can hard brick the device.

        Thanks.

        • http://www.jayceooi.com Jayce

          No need. I am still using the old bootloader right now.

          • Saduff

            OK, thanks for the info. I will upgrade to ICS tomorrow.
            As for rooting, which is better: to use CF-Root kernel or to flash an insecure root kernel and then flash back the stock kernel?
            Or if there’s a way that doesn’t increase the binary counter and doesn’t show the yellow triangle at all, then I’d prefer that method (keeps warranty intact and no need for USB Jig).

            • http://www.jayceooi.com Jayce

              Use CF-Root.
              Yes, use Mobile Odin Pro.

              • Saduff

                OK so I flashed the ICS firmware I mentioned above and Odin said pass, the phone rebooted and now it’s stuck on the boot screen (the screen with the S animation and Samsung Galaxy SII at the bottom). I see you fast-forwarded in the video at that stage, so how long does that take or is this the bootloop?

                • Saduff

                  OK, I booted into recovery and wiped all user data and the phone booted and the ICS firmware is installed. :)

      Which CF-Root and firmware version are you using now?

    im not root with CF-root,, just install insecure kernel and clockworkmod and my firmware version is GT I9100 XWKF3

      Sorry jamil, no idea about insecure kernel. Please consult insecure kernel guide owner for help.

  • jamil

    plz help i dont want root anymore i want my phone back only can i install full firmware for my phone

    • http://www.jayceooi.com Jayce

      Not sure it work or not. You can try to install official firmware with Odin. Hope it can solve your issue.

    • fx

      Hi Jamil,

      This happens to me before. Can you go into download mode (volume down+home+power button)? If yes, then restore back the firmware using Odin, as per Jayce’s suggestion. That should restore your phone back to normal.

      I’m not sure how you rooted your phone in the first place, but if you used the method here (CF-Root), CWM should be there by default, as well as clockworkmod recovery.

      Best of luck with your phone bro.

  • jamil

    thanks bro… and yeah i can go in download mode and i have rooted my phone with s2 root guide and install both insecure and secure kernel then after install clockworkmod recovery separately..

  • Yoshi

        I9100DXLP7/I9100OLBLP7/I9100DXLP7/I9100DXLP7

        from the following site;

        http://devsrom4android.blogspot.com/2012/03/i9100dxlp7-android-403-ice-cream.html

        When I unpack the archive file there is only one tar file. If I upload this using Odin will it load all the necessary files to support the Thai locale ?

        Regards,

        Yoshi

        • http://www.jayceooi.com Jayce

          Hi Yoshi, I have no idea about this site. Please get it from XDA website instead. By the way, Thailand does not have official ICS firmware yet based on Samsung Kies.

    Hi Jayce! Currently i’m using the MIUI 1.11.25 (pretty old!). Now i want to try samsung’s official ics rom by downloading it from kies. when i bought the phone, it came with XWKE8 firmware (android 2.3). So will i have to download the xwke8 firmware, install it through odin, unroot my s2 and then install the official rom? while trying an ics custom rom after removing miui, will i have to do anything extra (since i’m on 2.3) while flashing the ics custom rom?

    • http://www.jayceooi.com Jayce

      Just wipe data and cache in CWM. Then install ICS ROM.

      • Samarth Kumar

        thanks. that was a short but useful reply ! and best of wishes for a happy married life :)

    • http://www.jayceooi.com Jayce

      Hi Farhad, which method did you use to root your I9100G? Look it you semi brick it already. Try to install stock I9100G firmware with Odin.

  • ronaldos12

    hey jayce,where can i download lpq ics kernel for gs2?because i flashed siyah kerneand i want to get stock kernel

  • FCBarca

    I have an unlocked S2 that I was attempting to upgrade the firmware to ICS via Kies on a PC. Everything looked good bu at around 85% progress in the installation or downloading process of the update, it froze.

    Stuck on the ‘Firmware upgrade encountered an issue. Please select recovery mode in kies & try again.’

    I can’t get it to change from this screen and I can’t upgrade or reset the phone. I attempted the reset with the hold, vol. down & power buttons pressed but it brought me to the rooting option screen. I could choose to root or reset but resetting brought be back to the frozen screen I mentioned. I’ve restarted the phone (removing battery) and kies but nothing works.

    Am I only left with trying to root the device or can I somehow manage to get back on the upgrade track (Which I prefer)?

    • http://www.jayceooi.com Jayce

      Hi FCBarca, please consult Samsung Support since you fail to upgrade firmware through Samsung Kies.

      • FCBarca

        Carrier won’t be of any help then?…And rooting/flashing with official Android OS?

  • FCBarca

    Actually, I was able to reflash with a recovery/repair package via the xda site but it asks me for a PIN to unlock the SIM…Not sure how to approach this as it tells me I have 3 attempts left…I never had a code before

    • http://www.jayceooi.com Jayce

      Sorry FCBarca, I don’t have locked SGS2. No idea at all.

  • jessie

    hi jayce, i’ve been trying to do the firmware upgrade thing on my S2-GTI9100G (baseband version:I9100GDZKJ2) to the new KL3 version (using kies) but when it is at 100% (at the firmware upgrade progress), an error pops up :

    “PC failed to recognise the mobile phone:
    Please follow the guide shown below & try again:
    1. Disconnect the mobile phone from the cable,
    2. Press the power button
    3. Make sure the mobile phone has been turned on completely
    4. Reconnect the mobile phone to the cable & start the upgrade.”

    so, what should i do?? i have read on some forums that the usb driver has to be manually installed?? but when i connect my phone to the pc, everything seems to work fine (btw my pc is running on windows 7-64 bit..i wonder if windows 7 is good with kies)?..any help??

    • http://www.jayceooi.com Jayce

      Hi jessie, please consult Samsung Support sine you have problem using Samsung Kies.

  • Grim

    Hello, I have a SGSII with Android Version 2.3.4, and the Baseband version is 19100XXKH3, Kernel Version is 2.6.35.11-ninphetamine-2,0,5+ninpo@titan #20 and the Build Number is Lite’ning ROM v6.1 XXKH3. It’s a custom Flash ROM that i did with Odin, and i was wondering what version do i need to download to get 4.0 Ice Cream Sandwich upgrade?

    I don’t want to download/flash to the wrong Firmware, I live in Australia.

    Thanks,
    Grim

    • http://www.jayceooi.com Jayce

      Hi Grim, install back stock Australia firmware. Or any ICS firmware that you prefer.

      • Grim

        Thanks for the fast reply, how would i know what firmware is the Australian firmware?

        ~Also i was wondering, with this custom Lite’ening ROM flash i have, is it possible to Root it?
        If i root it, with the custom firmware i have installed onto my phone, can i brick it?

        Thanks Jayce,
        Grim

        • http://www.jayceooi.com Jayce

          Just search for ‘Australia’.

          Lite’ening ROM already have root access. You don’t need to root it again.

    hi,jayce
    I plan to buy JIG for my Samsung galaxy note.But i cann’t find JIG for SGN.So i would like to known S2 JIG can use on SGN?PLease ,reply me…zin

    • http://www.jayceooi.com Jayce

      Yes, USB jig is the same. But new bootloader on Samsung Galaxy S2, Galaxy Note and Galaxy Nexus disable the usage of USB Jig. So you can’t use it to clear the custom flash counter.

    Thanks for u r reply.

    hi, last month after upgrade ICS 4.0, i had rooted my s2. yesterday i receive a phone msg said tat hav a newer version, so i upgrade firmware by using kies. but after i finish upgrade, all my rooted apps (setCPU, super SU, autorun manager) cant use anymore. wat is happening? my phone is still consider root o not?

    • http://www.jayceooi.com Jayce

      Nope, you need to re-root it again.

      • timothykhor

        so now with this condition, my phone is consider unroot. if i send in samsung center for service, its still under warranty?

        • http://www.jayceooi.com Jayce

          No, you need to restore back to stock firmware (remove all root software like SuperSU). And clear custom flash counter. Please refer to this guide.

    Hello, I want to update from Gingerbread to ICS but Kies is not letting me do that. My s2 is PDA: XWKI4 and the CSC: CPW….I’ve downloaded the Kernel for XWKI4 but in AndroidFirmwares.net, there is only firmware for CSC: TPH and it is unbranded. Do you think it is safe for me to just download that firmware and go ahead with flashing my device with Odin? Will it affect my device in anyway or is there another option for me to upgrade to ICS?

    Thank you in advance

    • http://www.jayceooi.com Jayce

      Never use AndroidFirmwares.net firmware before, no idea.

      • HH

        Can you direct me to another website where I can download the correct firmware? I was directed to this site through the XDA link you pasted in your above post…also, if I do use a firmware for a slightly different CSC model but with the same PDA model then will it affect the performance of the phone or cause bugs?

        Thank you.

        • http://www.jayceooi.com Jayce

          Please get it at XDA website or SamMobile. CSC has nothing to do with performance or will not cause bugs.

    Hello Jayce, I also have a question regarding my S2. Actually my original kernel versiion before was DXKI2. But After i upgraded it to ICS Kernel Ver. DXLP7, it looks fine but i trace that my Use packet data is not working. I don’t know if its because i choose the wrong Kernel Ver. because iam leave here in the Philippines. So decided to search along the net to restore my previous version of DXKI2. So unfortunately i could’nt download these file on these following link:

    DXKI2
    Firmware info
    PDA:DXKI2
    PHONE: DXKI1
    Date: 08/09/2011

    DXKI2 Stock Kernel:http://www.multiupload.com/5PD9N57B0K
    Password: intratech@XDA

    Do you have any alternate link on this? Its really hard for me to look on it. Or do you have an answer why my Pocket Data is not working so that i will not restore again to old original packed version of DXKI2. Hope to hear you soon! God Bless!

    Hi Jayce,

    Can you tell what will happen if I flash with different kernel in order to remove the yellow triangle ? My phone currently is with the latest official ICS 4.0.4 Baseband I9100XXLQ6 , Kernel Version 3.0.15-I9100XXLQ5, Build number IMM76D.XWLPM – there is no stock kernel for xxlq6 or xwlpm on xda page. If I flash with kernel XWLPD which is the latest and with correct CF-Root kernel, am I going to brake my phone or I will succeed with removing the yellow triangle? What do you think ?
    Thanks

    BTW: I rooted with CF-Root-SGS2_XX_OXA_LQ5-v5.6-CWM5 and it was success.

    • http://www.jayceooi.com Jayce

      Hard to say. Better use USB Jig in this case. Easier.

  • tonakis

    I am not sure how to do it with USB jig, do you have instructions on that ? Or to get the risk and to try with the different kernel? :)

    Hi Jayce, I updated my Samsung Galaxy SII with Samsung Kies, Now I have some problems which I cannot solve :
    1. every touch makes an irritating noise, like krrrrk
    2. scrolling makes an irritating noise which becomes louder the more you scroll, beep-beep-beep
    3. swipe doesn’t work anymore
    notes
    1 it is not possible to turn off the sounds
    2 it is not possible to activate swipe
    How do I solve these problems ?
    Do I have to reset the firmware with Odin ?

      Hi cootje, try factory reset. This usually solve most of the problems.

          Hi cootje, you need to consult Samsung Support in this case.

            Just went to the Samsung Service Center (vodafone) ; first installed latest firmware via Odin, no succes for solving the problem. second tried factory reboot, no succes for solving the problem. checked water-damage : there was a signal just behind the opening for the adapter. So no guarantee anymore for me on my samsung.
            What’s next ?
            The problem came just after I upgrade the firmware. I would suggest setting it back to the original firmware might help. What do you think about that ? How can I find the original firmware ?
