Hey Bro,
Will your phone be unrooted once you have upgraded the firmware?
Yes if you install official stock firmware. Just reinstall CF-Root again will do.
Changing USB cable worked for me.change your Usb cable might it work for you also.try to use orignal data cable with the Odin.
i am facing an issue. i am from india i am updating my galaxy s2 firmware but my flashing process gets hanged at filename BOOT.BIN
KINDLY HELP ME OUT
Anything differ between yours and mine in the video? Using the same firmware as mine in the video?
yes i have used the same firmware as you have brother. it gets hanged at filename boot.bin?
Is Samsung KIES opened when flashing?
no mate. it is closed and i also have tried to stop my antivirus and firewall also.
kindly help. i want to update as my battery drain out very quickly
Hmm… Try to re-download it again. Else try other custom firmware see.
How to install other custom firmware? Else is there any other way out in it?
http://www.jayceooi.com/2011/08/13/top-android-2-3-4-gingerbread-firmware-for-samsung-galaxy-s2/
after flashing these roms do i also have to root my phone also? will my phone void warranty also?
Nope, most of them are rooted by default. But install custom firmware might void your SGS2 warranty.
However, you can always revert back to stock firmware after that.
hi brother. my problem is still the same. odin flashing gets hanged at boot.bin? why is this happening?
Changing USB cable worked for me.change your Usb cable might it work for you also.try to use orignal data cable with the Odin
i downloaded the firmware from the link you gave and did exactly as youve listed. though at the end, my kernel changed to xxkg5 but not my baseband and build no. my android version also remained at 2.3.3
Hmm… Anything differ between yours and mine in video?
Mine Worked fine
hmm.. the time it took to load to pass was much shorter, and there was no yellow downloading bar.
I guess that you are using the wrong file to install. You need to install the firmware. Not kernel. Usually, the firmware file size is more than 200MB.
i guess. so can you tell me where i could find the firmware? and would redoing it all over again do any damage?
The firmware is at the same place as you downloaded kernel. No harm to install firmware again.
@balpreet singh khaira: Try on other PC see.
Ok mate. any other suggrstion?
No for the moment.
thanks 4 suggestion mate. i have tried on other pc and it worked and now my sgs2 is running
xxkg5 firmware. thanks again.
but i wanted to ask what would have happened to my pc it is not working. should i reinstall
WIndows?? and if i want to root this firmware what will be the benefits??
Hard to tell what happened to your PC. You can format and reinstall Windows if you want. http://www.jayceooi.com/2011/08/17/top-reasons-to-root-samsung-galaxy-s2/
ok brother. thanks
hi brother i wanted to know that if i root my phone after which my binary number increases. Is there any way to reset binary custom number showed in ODIN download MODE??
The counter will increase when you flash custom firmware, kernel using Odin. USB Jig is the only way to reset it. http://www.jayceooi.com/2011/08/08/how-to-reset-custom-binary-download-counter-on-samsung-galaxy-s2/
ok brother. from where will i get this USB Jig?? any other way also??
I got mine from eBay.
But the Ebay people do not send this item to INDIA. Any other option??
hi bro,
your article is very helpful.. helps a lot to me on FW upgrade.
btw i wanted to ask about viewing videos on samsung galaxy s2. do you have any recommended player app which can directly view any .avi files fom my PC without any conversion? i tried to convert my .avi to .mp4 but doesn’t work well. when i open it on the default video player, it only plays 1 min and after that it says “file error”. i tried it on different files but got same error.
thanks in advance for any tips you can give.
I tested several video players but none of them are good in software playback. I prefer convert to MP4 and use default video player. You might want to try other converter – http://www.jayceooi.com/2010/05/08/best-free-video-converter-download-mediacoder/
@balpreet singh khaira: Make the USB jig yourself – http://forum.xda-developers.com/showthread.php?t=819551
hi

Sorry, I don’t sell stuffs. Please check with the sellers who sell it.
ok. But where can i find this USB jig in india?? How to make it?? is there any easy option of making??
Hi Jayce,
Just bought SG S2 two weeks ago. I noticed my S2 device is facing major problem, Automatically turn on Flight mode problem when make a call and make my call are being dropped and again after deactivate flight mode function after few seconds..
Therefore, would like to ask you is this normal problem for all SG S2???
Whether this problem will be solved if I upgrade latest firmware-Litening_Rom_v5-0.rar manually without updating from Samsung Kies???
Is this updating will void Samsung Malaysia warranty??
This is my firmware version;
PDA:I9100ZSKF1
PHONE: I9100XXKE4
CSC: I9100ZSKE7
Build Info: Sat Jun 4 20:01:14 KST2011.
Kindly reply is much appreciated.
Thank you.
Regards,
Leo
No, it is not normal. Try to hard reset. See the problem still occur or not. Don’t install custom firmware until this problem is fixed.
But I noticed there are a lot of ppl who are facing this poblem as well. They are sharing their opinions and problem under selected forum. But still no method found out yet.
Last week I wrote an email to Samsung Malaysia and they told me to do factory reset. But the problem still occur.
By the way, wat do u mean by ‘hard reset’???
please assist me to clarify this problem.
tq.
Hmm… In this case, you might want to upgrade to latest firmware DXKH2. See the problem still occur or not. If still happening, try to use other SIM card see. Hope this will help…
Hard reset == Factory reset.
Thanks for your reply. Just an additional question, among this two firmware, DXKH2 and UHKG7, which one is more stable and suit to my condition??? As android version is 2.3.3 and 2.3.4 respectively.
Better install Malaysia firmware DXKH2. You might need to send back your SGS2 to service if the problem still cannot solve.
Do I need to do “Quick Root” after completing “Flashing Firmware with Odin” (For upgrading Malaysia Firmware DXKH2)??
Furthermore, where is the link I can download Odin software??
TQ.
No. And use Samsung Kies to upgrade.
Samsung Kies??Connected via Samsung Kies, but didn’t see any link to upgrade firmware.. Please give me guidelines….
Did Samsung Malaysia already officially release Firmware DXKH2??
Yes. http://www.jayceooi.com/2011/09/04/how-to-upgrade-samsung-galaxy-s2-firmware-with-samsung-kies/
Jayce,
Pls help me to clarify this problem. When click basic information in Samsung Kies, it appear that “GT-I9100 Does Not Support Firmware Upgrade”.. But my existing firmware version is old version.
Is there anything wrong??
PDA:I9100ZSKF1

Oh, I just realize that your SGS2 is Hong Kong build. Correct?
Im not sure. But i bought it at Malaysia.imposible is Hong Kong built. But it appear that is ‘(KOR)’ at the end of built info in Samsung Kies…
Is yours AP or original from SME? If SME, you should receive SMS like this http://www.jayceooi.com/2011/07/22/where-should-i-buy-samsung-galaxy-s-ii-in-malaysia/
Malaysia CSC should be XME – http://www.jayceooi.com/2011/09/03/how-to-change-csc-on-samsung-galaxy-s2/
I had try your method to change the CSC. Unfortunately, I dont have any choices to click XME.
it only appear;
Sales Code: KOR
TMW
TGY
KOR
CWT
BRI
Therefore, do you have any method else??
As I mentioned, yours is Hong Kong build. So you don’t have XME. Please consult the seller that you bought the phone.
Or install any firmware that you want.
Ok… i will upgrade manually.DXKH2
..Do I need to do “Quick Root” after completing “Flashing Firmware with Odin”
Furthermore, where is the link I can download Odin software??
There is no CF-Root for DXKH2 yet. Odin download link is in the post.
hi jayce. how r u?
i need to inquire about
1. Is there any New Firmware for SGS2 Released?
2. Is there any other way of reseting the binary counter except the USB JIG??
With Regards
Balpreet
1. Yes.
2. No.
Which is the latest firmware?
http://www.jayceooi.com/2011/09/03/new-firmware-upgrade-for-samsung-galaxy-s2-xwkf1/
hi jayce
I am facing a wierd problem as my pc is not detecting my device.
i have updated my windows also butsome of the drivers dont get detected
whats the problem??
Make sure that you have Samsung Kies installed.
thanks a lot Jayce. Just upgrading to latest firmware. Tanx for ur guidelines.
Hey dude, I bought my sg2 from china, and there’s no Market app, etc…
The Kernel version is: 2.6.35.7-I9100zckg4-cl326202se.infra@SEI-29 #2
the Build number is: GINGERBREAD.ZCKG4
If I do this procedure to change the kernel firmware, Will my phone have the market app, etc…
If not, what should I do to change this?
Note, I’m not in china…
Thanks a lot
From what I heard… Sorry to inform you that China SGS2 can’t install other region firmware. It can only install China firmware.
No kidding…….
there’s not other way to change firmware? any kind of complete reset?!
Wait for official firmware upgrade from Samsung Kies. Sure you can factory reset it.
Samsung kies is installed but it also not detect my device. should i install kies again. also give me the link for latest drivers which r required.
Hmm… What is the error message? Does your PC detect your SGS2 when connect with USB cable when Samsung Kies close?
earlier it did not detect but i have reinstalled all the drivers again and now my phone gets detected by windows.
But my main problem is kies. it says
Reconnect the device in samsung kies(PC STUDIO)mode.Current connection mode not supported by kies.
Make sure that your phone is not in USB mass storage mode. Untick USB debugging. – http://www.jayceooi.com/2011/07/26/how-to-enable-usb-mass-storage-on-samsung-galaxy-s-ii/
I havr tried that also but no avail and now my odin fladhing is again getting hanged on filename boot.bin
How did you solve it last time?
solved it by flashing on another pc. But i want to do it on my own PC.
I am Confused whats happening with my PC.
Now I have run KIES and now it detects my phone and i have made backup.
But the real problem is that it happens sometimes and sometimes it does not happen.
DO I need To have a Rooted DEVICE In order to Update to a Custom Firmware via ODIN ??
Nope.
So are Custom Firmwares available in TAR Format ?? which is supported in ODIN … I asked you this question because whenever I go to .. a Custom Firmware Page on .. XDA .. etc.. The 1st step mentioned there is “1st of all you need to have a rooted DEVICE” and then they go on blah blah .. about soo many things .. whereas your instructions are soo Simple and Concise .. (straight to the point) .. so I have vouched to follow this Thread..
but I really need to be clear .. From where do I get Custom Firmware which I could ADD in Odin and Directly apply to my Device without Rooting it … (of course I know that after the Firmware is installed the Device will be rooted) my query is .. whether I could start off without applying CF ROOT.. and Clock work Recovery.. mod .. ?
Much obliged to your solutions .. JAYCE ..
Yes, in TAR format mostly.
So far Lite’ning ROM is the only custom firmware that I tested which can be flashed with Odin – http://www.jayceooi.com/2011/08/12/download-litening-rom-for-samsung-galaxy-s2-odin/
Most of the custom firmwares are in CWM format.
Yes, you can install any Odin type firmware without CF-Root and CWM.
Thanks
so If I ever want to revert back from CF-Root or Any other custom rom(with 2.3.4) for that matter would installing a stock Firmware (2.3.3) via Odin work or do I have to have a USB Jig for that ??
USB jig is only use for remove yellow rectangular and custom flash counter.
OK .. So basically CAN I Revert Back to 2.3.3 STOCK from 2.3.4 Custom .. Via ODIN .. without any issues right ??…
I mean .. Do I have to keep anything Specific in Mind while Reverting Back To STOCK FW ?
Yes, should be…
Jayce Im sorry .. I know am asking .. alot of questions .. but I really need to be sure .. on how to Revert back and whether I can Revert back or not .. .. please do help me out ..
are u sure there are no complications in reverting back ..
I have found my Stock Firmware on XDA .. based on XWKF3 (2.3.3)… so will this file work . If I apply it on Custom Rom(e.g. Litening 2.3.4) .. in order to Revert back ?
hey can this help to change baseband version too if cant is there anyother solutions because i want to update it to chinese firmware so thati could use it in chinese too.
Yes. Just install Hong Kong or Southeast Asia firmware will do…
hey where can i get it can you give me the link
Link is in the post.
I mean the link for the firmware for HongKong or SouthEast Asia sorry if i give you alot for trouble D:
Oh ok i downloaded the firmware DXKh2 alr but when i extract it with 7 zip it turn out to be a rar file what can i do to sovle this.
Any tar file in the rar file?

Hi jayce, I had flash my s2 firmware to xxxkg5 but i hv been having this problem of while
answering a call the screen blackout. During this blackout, no response to the touch screen,
unable to power off, also unable to end call.
Any one else facing the same prob ? Or is this a hardware prob ? If it is a hardware prob,
will I need to re-flash my firmware before sending to the svc center.
Is your proximity sensor still working? Or do you face this issue on your stock firmware?
No there is no issue with the stock firmware except for the usual heat issue n the draining of battery
Then it is not hardware issue.
so should I upgrade to newer official firmware by samsung KG7 or is there anyway to resolve this
Depend on you… Or you can try DXKH2 – http://www.jayceooi.com/2011/09/03/new-firmware-upgrade-for-samsung-galaxy-s2-xwkf1/
if i do send my set to the svc center, must i flash back to the official firmware ?
Better.
the proximity sensor is working
Hi Jayce,
Do u know of any sites that can upgrade Tab 7 from froyo to gingerbread ?
Try this – http://forum.xda-developers.com/forumdisplay.php?f=807
May I know which firmware version more stable and will enhance SGS2 performance especially Battery life… DXKH2 or XXKG5??? Please consult..
Tq.
I did not test DXKH2 battery life. So can’t comment on it. As for XXKG5 battery life, it is better than XWKF1.
How bout the performance and the speed for XXKG5?? I noticed that DXKH2 does not have any improvement except the language choice added…
Hmm… I did not benchmark it since XWKF1 performance and speed is okay to me already.
hi… how come my firmware is still the same 2.3.3 while yours is 2.3.4?….. my s2 has the same settings>About phone(same as yours). can tell me whats wrong?

New firmware should improve battery life.
If I were to install XXKG5 from XXKH3 (Frankenstein firmware) in my Galaxy S2 thru Odin, do I need to wipe my data & cache? Or is it better to just leave it and wait for new updates? Can’t seem to get Google video chat even on 2.3.4? Im on XXKH3 now.
By the way, I’m hearing echos of my own voice during my calls, is there a way to fix it? I’ve googled but can’t seem to find a straight answer
Yes, you need to wipe data and cache since you are downgrading firmware.
Thanks for the quick reply & advice. Is there Gtalk video chat with XXKG5?
Sorry, no idea as I don’t use it.

HI,,
I just update my firmware to 2.3.4 but there is a problem..
1. I turn off my phone and charge,after charging to 100%.
2. When I turn it on, it says in my battery widget 97% is this a bug or a my battery has a issue?
No worry, I have this symptom too. It will be 100% if you charge really full enough.
what you mean full enough sir?
I did turn off the phone and then waiting the icon of the battery 100%. T_T
There will be a fully charged notification when your phone is turned on. No worry too much. It is just 3% differ.
hi.. my concern now is that at 1st it was 97% but now 96%. daaaahhhhh……. it seems like there is a bug? for this firmware 2.3.4?
Change to other firmware if you are not satisfy with this one.

anyway thank you very much for sharing , you help a lot all newbie in SG2 including me..

You don’t need root access to upgrade firmware. But you do need root access to use Titanium Backup.
You can use all the applications that require root access once rooted your phone. Warranty might be void, but you can restore back to stock firmware.
thanks you Enlightened me.. you’re from philippines also
You are most welcome. I am from Malaysia.
Hi Jayce
I would like to know what Lite’ning Rom you use..
thank you
I am not using Lite’ning ROM. Using LeoMar75 ROM Revolution 2.7.1 now.
Thanks for the update and Odin guide,works very well.After the update samsung Kies in my computer says “cannot update this version”,any workaround for that,I thought this was an official release?…I have an unbranded swedish phone
Did you install Frankenstein firmware?
??..Don´t thinks so
Then it might be the wrong CSC on your firmware. http://www.jayceooi.com/2011/09/03/how-to-change-csc-on-samsung-galaxy-s2/
thanks for fast reply
There was some numbers you could dial in the phoone to make a workaround for that problem,was In one forum i read that but cannot find It now
Can you root with stock kernel 2.3.4 or do you have to use insecure kernel?
Use modified stock kernel ~ CF-Root. That the easiest way to root.
Do have instructions on rooting cos you’re the best man.

thanks again.
dear Mr.Jayce,
I have just got an unlocked brand-new SGS2 from ChinaMobile operator where I live ( did not use it yet )
I have already gone through all the threads above, and became happy to find an expert like urself who’s been able to help most of them
my problem is that – although they changed the settings to English – I still am getting many messages in Chinese ( which I don’t understand being an Arab )
the most am interested in are the following three:
1. GPS with English map and English narrating ( I mean the voice commands language )
2. to use Viber
3. to enter the world of Android softwares like free programs and games maybe
can I change from my firmware to an English one?
Model number GT-I9108
Android version 2.3.4
Baseband version I9108 ZMKH6
Kernel version 2.6.35.7 se.infra@SEI-27 #2
Hardware versioin I9108.01
Build number gingerbread.ZMKH6
I prefer to change the firmware to English using Kies, Would that be possible ??
Thank u in advance.
Sorry, this guide is meant for I9100. Not I9108.
thx 4 prompt reply …
I9108 is still SGS2 , isn’t it ? and which one is better I9108 or I9100 ?
can u pls help me out though
I’m so much grateful.
Unfortunately, in China u can not open utube, thus I couldn’t watch ur video, even with ultrasurf
is it uploaded onto any file share site by any good chance?
Thx a million
I don’t have much info about I9108. No comment.
By the way, don’t use any I9100 firmware / kernel on I9108. It might brick yours.
appreciate ur prompt reply
would you be so kind to me referring me to some link or someone which can help me out; am very new to the domain of smart phones ( it’s my first one actually )
I almost do know nothing about ur Jargon ( Brick – root – ROM – flush .. etc. )
yet am a bit confused … this post is for SGS2 and mine is SGS2 something am sure about.
may god bless u Jayce,
SGS2 has lot of models like I9100, I9100G, I9100T and US versions too. You can only use the stuffs developed for your own model.
I google I9108 and couldn’t find English website that has more information about it. Most Chinese. Sorry…
May God bless you too, Hussam.
Thx a lot 4 ur continuous knowledge contribution and expertise volunteering Jayce.
Today, I went to Samsung service center, and Mr.Feng – there – was wondering whether exchanging my device with an I9100 one, would solve the Chinese language problem. Would it ??
( He says I9100 is Chinese too, and with much less features than I9108 )
What do YOU think Jayce ?
I mean is it like I can get a firmware compatible with I9100 which is developed for ENGLISH speaking countries ?
You are the man Jayce
China I9100 is almost the same as I9108 (it is not same as international version I9100).
If can, ask for international version I9100. You can use Arabic, Europe, Asia region firmware. That’s the model that most of the people is using.
thx a lot Jayce,
what’s the differences between the international version I9100 and my mobile I9108 ?
CPU / GPU and firmware are not same.
Hi Jayce, I’ve been reading ur website on how to root and stuff. Currently, I’m using S2 2.3.3 Gingerbread DXKI2.
1) Can I flash XXKI4 or XXKI8 from here?: http://forum.xda-developers.com/showthread.php?t=1075278
2) Or can I straight away flash Miui / Lightening Rom 6.1 using Odin?
Thanks in advance.
1. Sure.
2. Yes, as long as the firmware is in Odin tar format.
Hi jayce I bought SGS2 1 week ago in pakistan firmware version on my phone is XWKG1. now I want to install JPKG2 version so i downloaded the file in 7zip now when i extract the file, rar file comes out of it then i extract the rar file 6 files comes out but the tar format which u shows in video is not available. pl help

International I9100.
Thanks for the guide ! I’ve just flashed mine to 2.3.5

Hi Mr. Jayc,do u know when we get ICS Rom for sgs2?
CyanogenMod team should come out 1 month after the ICS source code was released, around Q1 2012. Official firmware needs to wait until Q2 2012 or later.
Hi Jayce,
Need advice.
I have brought a new SG2 contract phone 3 weeks back and updated the firmware as below from Kies.
Version: 2.4.5
PDA: XWKI4
PHONE: XXKI1
CSC: XEUKH2
Just planning to upgrade my firmware to 2.3.4 to 2.3.5 because of batter performance. Before i processed, i have questions on my mind.
1. Can i upgrade to 2.3.5 with my current version?
2. If i upgrade firmware without rooting my warrenty still valid?
3. If i’m not rooting my phone. what kind of issues i will face in future upgrades or with market place?
4. If i upgrade my firmware to 2.3.5 and rooted. Can i pull back my pervious version (2.3.4)?
Appreciate on your advice.
Cheers.
Sabba.
1. Yes.
2. Install other region official firmware might void your warranty.
3. Hard to say. Bugs do exist from time to time…
4. Yes.

Hi Jayce
I want to remove everything off my phone and install new firmware. Will the installation wipe everything automatically or how do I delete everything off first?
Thanks heaps.
Official firmware is non wipe normally. So you need to delete them manually. http://www.jayceooi.com/2011/07/18/how-to-hard-reset-samsung-galaxy-s-ii/
Great, thank you!
hi jayce,can i flash speedmod or siyah kernel on official stock rom???
I think so. Make a CWM backup first before try them.
I just got my GS2 and I am confused. If I want to flash CFW, do I need to root 1st? Or just download the CFW and flash with ODIN? And the kernel version? Different version have different CFW? Can I mix them?
What is CFW?
Custom Firmware.. Sorry have been cooking Symbian for too long..
There are 2 type of custom firmware ~ ClockworkMod (CWM) and Odin. CWM ROM needs ClockworkMod Recovery to install. Odin ROM needs Odin. You can try different kernel on custom firmware as long as they can work together.

Hi Jayce
I recently bought Samsung Galaxy S2, and i observed that it is having heating issue (slightly). I read in one of the forum that its Firmware need to be updated in order to overcome this issue. But i am not sure if my version is latest or not. Please find the details as follows:
PDA: I9100DXKI2
Phone: I9100DXKI1
CSC: I9100OLCKH1.
Could you please let me know if it is the latest one. If not what procedure do i need to do to update the firmware. ?
Your firmware is the latest for your region. Samsung Kies will let you know if there is new firmware upgrade.
Thank you very much for this update. When i check the version of android it is showing as 2.3.3, Could you please tell me if it is the latest version or not. If not, could you please tell me how to install the latest version which is officially available for samsung galaxy S2.
As I mentioned, connect your SGS2 to Samsung Kies. It will let you know.
Unless you want to try other region firmware. Then you can install them with Odin.
Thank You so much. I also need 1 more help.
When i copy video into SGS2, it is always asking if i need to automatically convert the file. If i convert and copy it is taking much longer duration and the resultant video is not really smooth. Also could you please advise me on how to play the mkv files.
Don’t convert it. SGS2 stock video play can play MKV video.
Or use this method to copy files – http://www.jayceooi.com/2011/07/26/how-to-enable-usb-mass-storage-on-samsung-galaxy-s-ii/
Hey Jayce ,
Could you tell if i install an official samsung firmware ( FROM DIFFERENT REGION than mine) then do i need to root my phone ? I am from India and currently the latest firmware here is 2.3.3 but i want to shift to 2.3.5 (EUROPEAN region firmware). So do i need to root ? Or simply follow the procedure you told in this post ??
Rooting is not a must. Only do so if you need to use apps that require root access.
jayce : my sdcard unavllable after i restore my data from CWM… how to safe my sdcard?????
I faced apps installed on SD not found issue after CWM restore. But the internal sdcard is still accessible. Reboot helps sometime.

what does this mean?
Thanks
Are you using Galaxy S2?
Yes.

This is the log on odin

Have not see this sign before. Try to connect to Samsung Kies see.
still the same because the screen still shows the same and cannot go to recovery mode.
Thanks
Please consult Samsung Support then.
Ok sure
Is it flashing rom / using odin would not void the warranty? any experience or info from friends?
Flashing your region official firmware with Odin won’t void warranty. But other region and custom firmware do.
Glad to hear that
Mine also from Malaysia with default OS 2.3.5, baseband KI1. yours is KI3.
Thanks for the info.
Hi there, i need help about my samsung galaxy s 2, can?
Sure, what is your question?
i’d try to upgrade my sgs2 firmware to 2.3.5 from my 2.3.3, but, it failed. What should i do now? when i turn on my phone, its display “firmware upgrade encounter an issue, try recovery with kies something…” i tried, but useless, the pc can’t even connect with my phone… so what should i do now? i have no idea, any tips or guide? thanks.
Which firmware did you install? And are you using I9100G?
mine is GTi9100, don’t have the G? not sure about that. My case same as the above. Hmm, too bad. What else i can do? the firmware that i install is the xxkg1.
Where did you get xxkg1 firmware? I can’t find it at XDA.
i get it at the samfirmware.com? hmm…i really have no idea else what to do. If still can’t fix it, i think i need to send my phone to samsung service center… sigh.
Yes, better do so if you can’t load Odin download mode.

Hi jayce now my s2 firmware is XXKG5 but i encounter prob. i log in my facebook the site loading for sometime. i waited for few min n it just keep loading… is it because of the firmware i cant load my FB
Sorry, no idea. You can try other firmware see.

Yes.
Hi sorry to disturd. i need to downgrade just the stock kernel or have the downgrade full XWKF1.. help pls
Full firmware.
hi , jayce , after i install i9100xxki3 , i cant type chinese =(
XXKI3 is Europe firmware, so no Chinese input. Just install Google Pingyin IME.
Just flashed to xxKi3, my desktop keeps on restarting, and reloading
Factory reset it. http://www.jayceooi.com/2011/07/18/how-to-hard-reset-samsung-galaxy-s-ii/
Seems to be fine now, i removed battery and micro sd for about 30 secs, then plugged it again. its hard to download with all my apps, if problems persist ill do a factory reset. thank you!
DOES it exploit its warranty ?
It might when you install other region official firmware. Custom firmware sure void your warranty. No issue when install own region official firmware.
can i update my galaxy s2 if its current firmware is xwkf3
Sure, why not?
can u plz explain me in detail if the update fails?
Boot loop might happen.
what is boot loop
You still see SGS2 logo hanging there (sometime phone restart). Can’t load into Android OS.
If I download this software on my Chinese Galaxy 2, will it work properly (if at all)? Also, will this delete memory?
No, your phone will become a brick. You can only use firmware developed for your China SGS2.
Hell Jayce
I am from india and i installed a custom rom on my phone thru CWM but it just gets stuck displaying GALAXY S2 Logo with yellow triangle and doesnt go further and aslo get an error E: cant mount
dont really know what happened it jus doesnt accept any custom rom firmware but runs stock firmwares
pls help me
What custom ROM did you install?
I’ve been to Jeeba’s shop. Truly a great place with fair prices. About time the move took place.
Hi,
I cannot get my SGS2 connected to PC, despite usb debugging, usb connection enabling etc etc which are suggested by some forums.
So I am not able to upgrade!
Any ideas how to fix this problem?
What Android version and firmware are you using?
It’s 2.3.4 XXKG6
Do you have Samsung Kies software on PC?
Yes, I do.
However it has also failed to recognize my SSG2!
Hmm… You should be able to connect with this firmware and Samsung Kies installed.
Did you try on other PC?
yes, no luck with 2 more PCs!!!
You might want to factory reset your SGS2 in this case then.
I managed to upgrade the firmware to 2.3.6 XWKK5 using mobile odin.
It flashed smoothly.
Now the phone shows:
Android version:2.3.6
Build number: Gingerbread.XWKK5
Kernal Version:2.6.35.7-I9100XWKK5-CL754841
However, the baseband version is still: I9100XXKG6 ( I HAD XXKG6 firmware installed before current upgrade). Is that OK?
Also, the sound is quite distorted right from the bootup.
I am still unable to get connected to PC.
BTW, I did a factory reset, but my wall paper is still there.
Please help.
I am not sure. I did not try XWKK5 firmware.
Your custom wallpaper should not be there if you factory reset. Everything should be back to original stock settings after factory reset.
Can you please let me know how you factory reset your device?
Thx
http://www.jayceooi.com/2011/07/18/how-to-hard-reset-samsung-galaxy-s-ii/
While waiting for your response earlier on, I reflashed and then factory reset twice.
Just now I followed the 3rd method that you suggested.
Now my old wallpaper doesn’t show up any more.
However, the sounds are still distorted.
Any tweaks to correct this problem?
No idea. I did not try XWKK5 firmware.
Is XWKK2 good?
Maybe I should flash that one now.
I did not see issue during my testing.
Hi Sir,
I just wanted to know if i update my phone to 2.3.6 using your method will i still be able to update to 2.3.7 or 4.0.1(if any) provided by Samsung through Kies ? Also do i need to root my phone before using Odin to put 2.3.6 ? And does manually updating would put any bloatware or any other additional app which is unrequired or not in english?? And is this update be ok for an indian version of S II which is still officially stuck to 2.3.3?? Also is this a global version of 2.3.6 or a region specific update which would be pushed to other S II ??
SORRY FOR TOO MANY QUESTIONS !!
Also a quick reply to my queries would be appreciated… Thanxs in advance !!
Yes but from Europe region firmware. No root access is needed. It will have apps for Europe. Yes, as long as your SGS2 is GT-I9100 model. Not global but for that region only.
Installation works properly.
Thanks
Hi jayce
XXKI3 and XXKI4 which battery life is better? read from xda forum that quite a number of people complaining XXKI4 drain a lot battery power compare to XXKI3
They perform the same to me.

Probs updating to Gingerbread 2.3.5 via Kies & Win 7
Hi Jay
I’m having probs updating my S2 to 2.3.5 (the latest available, here in Italy with my provider .- from Gingerbread 2.3.3). This is the routine:
1. I connect the phone, start Kies & then I get the message saying a firmware update is available.
2. I click to accept & Kies downloads the update (tho I think it disconnects the phone in the process).
3. A window appears saying Kies is preparing the update, but here it seems to freeze up.
4. Whilst this is frozen, Kies (in the background) presents a msg saying a new firmware update is available (as in point 1, above).
Kies is up to date (in fact I’ve updated it 3 times & installed/uninstalled/reinstalled each version – same result).
I also download ODIN 3 v1.85 (to try as per your vid, above), but it crashes as it opens.
I have a Windows 7 32 bit on a laptop & a dongle internet connection.
Any ideas?
Thanks in Advance
Suspect your Windows is unstable since both of the apps can’t work. Try to use another PC or format your Windows then try again.
Hi Jayce
thnx for getting back to me – I’ll give that a try
cheers
p
will these wipe all my data inside the phone and do i need to root it before upgrading? if so how do i backup everything? i’m totally new to this and i’ll be thankful if you can help.
Most of the official firmwares are non wipe version. Backup with Titanium Backup if your phone is rooted.

Hi,
I got a korean set SGS2 model M250S. Due to the limitations of the Korean Characters, the sms can only type 80 characters. I am from Singapore and wanna flash a Singapore original firmware. I am very very new at this so I am wondering if I need to root my phone before following your tutorial? And what version of the firmware should I download? Please advise. Thanks a million
Kernel 2.6.35.7-M250S.EE31.2118-CL220682
Firmware: Gingerbread EE31 version 2.3.3
Not sure I9100 firmware can be installed on M250S or not. Please consult others at http://forum.xda-developers.com/showthread.php?t=1097347
Thanks for the prompt reply. Users from XDA mentioned that it is possible to flash original firmware into it. So do I need to be rooted? and which firmware should I be looking at?
No need root access when install firmware with Odin. Which firmware to install? I have no idea.
I tried to do it. Since people at XDA said that it is possible to flash european stock firmware into M250S. I followed your instructions but Odin said it failed. Now I am stock at boot saying upgrade not complete, try again.
Help please…
Sorry, I have no idea since I don’t have M250S. Please consult the person that said possible to flash it.
I have flashed my samsung galaxy s2 via odin using single file I9100XWKL1_I9100ODDKL1_INU but it did not delete my previous apps, moreover the factory reset is just deleting my apps not sd card data though I have selected to erase sd card data too..Last time when I have flashed for 2.3.5 it had 3 files and it was a fresh install asking me to enter email id and time after installing the firmware but this time it did not happen….can you explain me what is the difference between flashing using single file and flashing using multiple files…???? I have googled about it but they’re it says it does not make any difference…
I want a fresh install like last time…
and I have downloaded the firmware from sammobile…
I did not try firmware from SamMobile. No idea what is the difference.
Hi, Jayce. I have just rooted my SG2 (XWKI4 – Android 2.3.4 Gingerbread ) with your video guide and everything went smooth and perfect – thanks. Now I think to update my firmware to 2.3.6 which according all info is the latest official. I have some questions:
1. From the link you`ve provided ( http://forum.xda-developers.com/showthread.php?t=1075278 ) which Firmware you think I should download?
2. From that same link what exactly do I need to download – kernel stock and the pkg with the firmware ??
3. If I do firmware upgrade to 2.3.6 and kernel upgrade also, will all info from my phone be wiped ?
4. Now, when I got my phone rooted, which program will you recommend for backup of my data ?
1. Depend which region firmware that you prefer.
2. Just firmware will do. Kernel no need.
3. Most of the official firmwares are non wipe (unless mention).
4. Titanium Backup.
What will you say regarding:

i had few apps on my sd card but i had to format it as it was corrupt and making my phone restart again n again
but some how i managed to recover com. files or android secure folder data now would you plz guide me how shall i recover those apps
Try to use undelete software to recover them.
that software is of no use i guess
i have used that software before also but it only recovers media files that too cache
is there any other way???
Nope, unless you have backup with CWM or Titanium Backup.
no i don’t have that means i lost those apps i guess
anyways thanx 4 helping

would all the apps will be lost after flash the new official firmwarre 2.3.6 using ODIN?
would it effect anything like 3G network?
TANX.. I LOVE MALAYSIA <3
Normally, no. Unless you face boot loop when downgrade firmware. And you need wipe data and cache to solve it.
Hi,
I followed the instructions in ur website to flash the ROM of my galaxys2 with one of the Frankenstein firmwares given in the http://forum.xda-developers.com/showthread.php?t=1075278 website. My vendor (Bouyges Telecom, France) currently provides Ginger bread 2.3.4 version . But I am running a Frankenstein firmware version of android 2.3.6. Now i just booted in the ODIN mode to check my firmware version and binary count. It says “samsung official” and the count is still “zero”.
However,,, Samsung keis does not recognize the firmware of my device for updates. So my question is ,,, will the warranty for my device be void ? ? Could you please give me some information on this?
Thanks,
Venkat
Yes, and no. Depend on the Samsung Service Center. Some accept custom ROM but some don’t.
Hi,
Thank you for the reply. I have few more questions. So ,, if you say mine is a Custom ROM (my ODIN download mode shows that I have Samsung Official Rom and Custom Binary counter is still 0) why is my Custom binary counter still showing 0 count and why is it still showing “Samsung official” firmware? ? What does that mean then ? As i told u mine is a Frankenstein firmware running Android 2.3.6.
So does this mean that,, if i have to flash my firmware back to original vendor provided ROM, I dont need to reset this Binary counter using a USB Jig (since mine is already showing 0) ? And I ll safely be entitled for to my guarantee again ? ?
Thanks,
Venkat.
Your is mixed region official firmware. Not a custom ROM that will increase the counter.
No need to use USB Jig since the counter is still 0.

Best firmware is depended on your usage. Personally, I am using Europe custom firmware.
is it okay if i use European firmware ? im from philippines. but my phone is not bought in here.
Yes, mine is Malaysia unit.
Does firmware upgrade of reinstalling of the same firmware will remove the applications? I have some applications which are giving problem to me and I cannot remove them through the phone. How do I remove these applications?
No. Factory reset your phone.
Even if I perform the factory reset I cannot remove these applications? Is there any step in the factory reset procedure to select the applications to remove/keep after resting?
Then those are system apps. No.
Thanks for the reply. Some of these are QQ PhoneBook, QQ Security etc…
Hey Jaycee,
I bought my phone in China 2 weeks ago and I would like to change it to any firmware but from what I understand a lot of people brick their phones! Since I usually use gmail and want to use the english version of android market. Is it safe to do it your way? I have no knowledge so I’d rather ask before I do anything with my new phone. I hope you can help me
Thanks in advance,
Loic
Sorry, China SGS2 cannot use I9100 firmware here. It will brick your SGS2. You need find firmware for your SGS2 in Chinese website.
THANK YOU SO MUCH! I kept flashing my phone (that was stuck in bootloop) with the XXKG1 firmware, since I couldn’t acces the phone and go to “about phone”. So I looked at my dad’s SGS2 from maxis, and it said the firmware was XXKG1, so I thought mine would be the same since I purchased it from Malaysia (not in maxis though). But it kept being stuck in the bootloop. Then I tried your firmware, and that did the trick. So I’m guessing Maxis gets their phones from USA or Europe and not from asia since XXKG1 according to XDA is not from asia, it’s from europe. Hmm strange. Anyways, thank you so much! Keep it up!.
What if odin says FAILL instead of PASS!?!?!?!? WHAT DO I DO THEN????
PLEASE HELP!!
Which firmware did you install? And which SGS2 model are you using?
i have the epic 4g touch SPRINT version and i tried to install the SPH-D700 firmware??
I am sorry. I don’t have Epic 4G Touch model. Did not research much on it. No idea…
Stuck in boot.bin means you forget to enable USB debugging mode in setting – Application – Development. Hope it helps
And if you don’t want to install KIES in your PC, you have to install Samsung mobile USB driver in your PC so your PC can detect your SGS II
is there swedish language in CF-Root-SGS2_XW_NEE_KI8-v4.3-CWM4?
CF-Root is a modified kernel. Firmware is the one that control language.
Ok Thank you.
Absolute legend. Thank you
All working after two days of anguish without my phone! Thanks very much indeed!
my phone is samsung galaxy fit how to upgrade android plz help me……….!!!!!!!
Sorry, I don’t have Samsung Galaxy Fit. Please consult Samsung Support.
hi, i bought my samsung galaxy s2 from online. it was brand new but from hong kong. i live in australia, when i plugged my phone into the computer to transport data it asked me to update firmware. when i clicked yes it got stuck on 10%. Now the phone wouldnt turn on anymore and samsung australia doesnt help me because they say its from hong kong and hong kong recovery firmware needs to be put into the phone. Can anyone help me with this….how can i get the firmware update hong kong version from kies???
Sorry to hear that. You can’t do anything if you can’t even power on it.
well i can power it on. but when it turns on it jst says connect to the computer.
I can also power it on the way you have said by pressing volume down + lock + home key. I can add the software via odin. but all i need is the correct firmware. I was wondering if u knew how i could get the firmware. thats all i need, i can recover it by putting the recovery firmware. that is all i need!!!
The firmware download link is in the article.
i have tried the links. but the vivelink downloads dont work for me for some reason. im not very I.T savvy so its more confusing for me. and how can i use my imei number to know where my phone is actually built so i can download the correct firmware?? isnt there another way to download the firmware?? Thanks
You need to check with Samsung Support on where your phone was built.

G’day,
I purchased on eBay the Samsung Galaxy S2 Epic Touch that is CDMA hardwired for Sprint. I live in Canada and my server is Telus. I need to break the root and to unlock it. Can you help describe the steps necessary to be able to use my server and optionally stop using my old and slow?
I am also unsure if I should wait for ICS as it has Gingerbread 2.3.6 but still unable to make any logical connections as still locked. I guess my main question is how to unlock it.
Thanks bud!!
Cheers
Bob
Sorry Bob, I don’t have Samsung Galaxy S II Epic Touch. No idea…
Hi Jayce
I was using my Samsung galaxy S2 for a while and suddenly today all the contact is missing from the mobile. I am able to get a back up from Sim card and rest is completely gone. Could you please help on this !!!
Thanks in Advance
Visakh
Do you have backup with Titanium Backup? Or are your contacts stored at Google Account?
So far i havent used any backup apps (titanium) and i am not sure about backup in google account.
Just login to Gmail. Then select Contacts.
By the way, better put all your contacts online in Google Account. I do that. You can sync all the contacts with any Android phone then.
Alright. Let me try. Does titanium is a best way to take backup of contacts ?
Yup, Titanium Backup is the best backup software for Android.
hi brother,i bought my unlocked samsung galaxy s2 from ebay and it was working perfectly for a month and after that stoped and when i went to the repair shop they told me that has been blocked by the company and i need to get in tuch with them and i dont know which company is that,is there is any solution please?
Blocked? Try to consult Samsung Support.
hi jayce. i was using 2.3.5 xxki4 as suggested by you earlier.. it all went well.. n my phone is rooted as well.
now if i wanna upgrade to xwkk2 2.3.6, how am i to do it.
since its already rooted i don wanna take a chance. please help.
Install XWKK2 firmware with Odin. Then root it again with CF-Root.
Only 3 questions Jayce
1.Have you tried Hyperdroid androidmeda ROM 2.3.6.?How is it?
2.If I have to install it,should I wipe data/cache first always ?If I dont like it,instead of flashing stock firmware again,can I just restore my stock image through NANDROID?
3.what do you suggest?installing rom through CWM recovery(sdcard) or ODIN?
Please reply.thanks
1. No.
2. Yes. Yes.
3. Depend on the ROM format that you install.
Thanks,so I assume that restoring through NAND(CWM) is alternative to flashing stock firmware(in fact better,since it will even come up with apps installed;while I’d have to reinstall apps using TB in latter case)
Which custom ROM(official) do you think is best?(battery saver too)?
Yes, you can restore stock firmware (if you have backup previously) through CWM.
Using CheckROM RevoHD v4 now.

Since you can’t install I9100G firmware, please send it back to Samsung Service Center.
Hi… will the warranty be void if i install donwloaded firmware i.e. i9100kpnkj1/xwkk2 into my sgs2? Instead of getting the updates from kies? Thanks.
It might if you install other region official firmware with Odin. But you can always install back your stock firmware with Odin too.
i have updatred firm ware pak-1900jpkj2/i900ojpkj1 andriod 2.3.5 ginger bread.after updating my phone restarting one by one what can i do.just restating nothing happening
Do you mean that you face boot loop issue? If yes, wipe data and cache in recovery mode.
