Download CF-Root for Samsung Galaxy S2

Download CF-Root for Samsung Galaxy S2


Thanks to XDA Developer, Chainfire (Donate him) for his CF-Root for Samsung Galaxy S II. Basically, CF-Root is a modified kernel based original firmware kernel by adding root to it. Besides, it also adds BusyBox, Superuser, ClockworkMod recovery and CWM Manager. It is one of the ways to root Samsung Galaxy S2.

Samsung Galaxy S2 Kernel Version

There is a lot of official Samsung Galaxy S2 firmware such as KE2, KE7, KE8, KF1, KF2, KF3, KF4, KG1, KG2, KG3, KG6, KH1, KH3, KH4, KI3 and KI4. You cannot simply use anyone of them. So which CF-Root should I use? Find the closest one that matches your Samsung Galaxy S2 kernel version. To check your kernel version ~ go to Settings – About phone. For example, my SGS2 kernel version is root@DELL106 #2. Look for KF1 first, then XW. Therefore, XW_OJV_KF1 is the CF-Root that matches my current kernel. Make sure that you download the correct one for your SGS2.

          • tan boon kok

            oh! I dnload direct to my sgs2,is it htat I require to dwn load to computer 1st?

            • Oh, it won’t work on mobile browser due to redirect permission that I set. 😛

  • AndroSid

    Should usb debugging be enabled before rooting with CF-Root please help i am new to this

    • I did not enable it if not mistaken.

  • ferdi

    I have kernal version BOKF3 from t-mobile what CF-Root for Samsung Galaxy S2 do i need to download ?

    • Hmm… You are using carrier branded firmware. Mine is not. Therefore, I am not 100% sure that it will work for you. You can try XW_CLK_KF3. Or get more information at

      • ferdi

        first i tried with odin and super oneclick … but super one ckick didnt work for me . ( stuck in the middel)
        after that i used this kernel in odin XW_CLK_KF3 and now he is rooted i can use titanium.
        but in the setup screen i still see t-mobile blabla but i dont care i hope i can upgrade soon to a newer android version

        ty jayce

        • Glad to know that your phone is rooted. With CF-Root, you are able to install custom firmware with CWM now.

  • curtis

    it does not have my kernal on it

    • curtis

      i have kernal buke it not on there

    • What is yours?

  • Wouter

    I’ve got Kernel KE4. Which CF-Root should I download?

  • Wouter

    Never mind, downloading KE7 now. I saw a lot of SGS2 users with Kernel KE4 with KE7 installed, so I will give it a try.

  • Wouter

    Sorry for spamming your page :p
    But I just wanted to tell you that KE7 works fine, I even think the battery life is better now 😀

    • Glad to know that. 😉

    Hi Jayce

    i got kernel version XWKDD. which one i must use


    • XWKDD is a old firmware. Not sure which one for you. Maybe you can upgrade to latest firmware first and apply CF-Root then.

      • joseLuis

        I Rooted my phone but have the yellow triangle. ! I do have the XWKDD old firmware, !

        Can I still update the firmaware even it is rooted, ?

        I may need to update the firmaware in order to remove the yellow triangle, correct ?

        Thanks on adnvace for you kind help. !


        • Yes, you can upgrade firmware with Odin even it is rooted.

          Install official kernel will remove yellow triangle. But install custom firmware / kernel will it back. 😛

          • Jose Luis

            thanks for your answer Jayce,

            a last question do you recomend to bacl up right ? I dont have the original since I din’t back up, these time I will back uo the ROM if you recomend to do that,

            What is the ROM Back up software you recomend. ?


            • Use ClockworkMod recovery to backup.

              • Jose Luis

                Thanks a lot for you nice help. !

              • Jose Luis


                I downloaded the ClockWorkMod ROm Manager Versio 4..5.0.1

                but a the time of Back up the ROM the phone Boots and then sends an error mesage
                do you hace any tutorial for ROM Manager _backup ?


                • ClockworkMod recovery does not working properly on CF-Root kernel.

                  • Jose Luis

                    right after trying to backuo it goes to recovery mode and then trys to update ROM then it fails.

                    any advise

                    • What ROM do you want to update?

                    • Jose Luis

                      to any release where I can now delete the trianguele, mmh ! I saw the link you provode it goes to XDA, can I update from Kies ? or only by Odin ?

          • Jose Luis

            Thanks for advising,

            That’s how I rooted.

            1.- Used Odin3-v1-1.85 to INSTALL INSECURE XWKDD_insecure (PDA)
            2.- Use Spuer Click to Root.
            Issue: I cannot move to recovery mode since looks like the recovery mode is not even stating up, it break at the update option.
            Seems like I should better update the ROM

  • acidsulfurik

    hi bro! im using SGS2 but already got an upgraded Android Version which is 2.3.4. got that kernel after upgrading my phone’s firmware via Samsung KIES.

    so my kernel version is now – #2..(the kernel is not rooted yet after i checked using Root Checker)

    so quoting your text..
    “XWKDD is a old firmware. Not sure which one for you. Maybe you can upgrade to latest firmware first and apply CF-Root then..”

    how can i upgrade to latest firmware? thanks in advance!

  • evan

    hi jayce i had install firmware i9100xxKg5 from your website is working but i got one widget can’t use it like mini paper only ,why i install back to firmware i9100xxkf1 many function can’t work any more, is it i made mistake thanks.

    • Did you wipe data/factory reset before downgrade to KF1?

      • evan

        no ,how to wipe data/factory reset cause i didn’t root my s2 yet thanks.

        • That might be the issue. You can wipe data/factory reset without root.

  • evan

    how can i do it ,is it push velum down and home and power thanks

  • Andre

    Hi Jayce

    My problem is that my kernel version is XWKEB !!!! there is no match according with your posted list !!!!

    The last digit always ended with a digit( posted list)… not my case !!! it ends with a letter !!!

    I already try to update via samsung account but there is a problem with Internet connection


    • Sorry, I have no idea too. Or maybe you can install other version firmware first. Then root it.

  • Kunwar

    Where can I get CWM Manager application?? Its not on market or appbrain. I flashed a diffrent rom and CWM is missing. Also is CF root compatable with Rom Manager??

    • It comes along with CF-Root. No, it is not compatible with ROM Manager. But you can always boot into ClockworkMod recovery mode directly.

  • Bjill

    Hey good info but it doesn’t look like my CF-Root is listed…….XWKEB

    Or will the XWK2 do the job?

    • Not sure, but you can try it.

  • Kunwar

    I ment to ask I have flashed miui rom. I do not see cwm manager. Is there cwm manager.apk which I can install??

  • muaidh

    in the top left corner of Odin saying ID:COM with Com being a port and this text should be written in yellow as shown in the vid. but don’t have that and i can’t root my device. could you please help

  • steve

    i hav XWKDD which one do i need to download???

    help meeee and thank you

    • Sorry, not sure which one for you. Maybe you can upgrade to latest firmware first and apply CF-Root then.

  • Zeno

    Hi jayce, first thank you for everything you help me alot with my sg2.

    my question is im using JPKF3 right now and i will upgrade to JPKG5, so which root to use JP_XSG_KG5 OR XX_OXA_KG5? and what the different between them


    • Should be JP_XSG_KG5. They are different firmware version. No idea on the detail. 😛

  • khim

    hi Jayce, my galaxy s2 kernel version is kernel version is ,can i used according with your posted list ??

    • You can try XW_XEU_KE7. That’s the nearest to your kernel.

  • Alex

    I have kernal version BVKH1 from orange (Spain) what CF-Root for Samsung Galaxy S2 do i need to download ?

  • wewe

    hi Jayce, my SGS2 Kernel version is se.infra@SEI-29#2 – what CF Root fits my device? thanks!

    • Sorry, I am also not sure…

      • wewe

        is that so, in this case i might not root my device? 🙁

  • wewe

    hi jayce, can i use the kernel that is listed on this page
    Since I got my SGS2 in Japan, and my carrier is DOCOMO.

    but, which of these two? – SC02COMKG5.exe – Kernel_SC02COMKG5.exe

    thank you in advance

    • Yes, that should be the one for you. SC02COMKG5.exe is the firmware. Another one is just kernel.

      • wewe

        Thank you so much! I will update you after I run all the procedures on my device. 🙂

        • wewe

          hey jayce, i rooted my SGS2 succesfully. I used this firmware (JP_XSG_KG5) because the one that I downloaded (SC02COMKG5.exe) for my phone didn’t work. But still my phone is now rooted and I’m very glad about it. Thanks for the help.

          Anyway, I like to remove the yellow triangle on my device where can I download the zImage file? And how about the stock kernel? It is in .exe format but from your instruction we need to extract the .tar file? where can I get the .tar file stock kernel for my device? please help. thanks!

  • hesam

    hi i have
    kernel verison jpkf3-cl303619root@dell101
    #2 in samsung galaxy s 2, which one may i use? please help me

    • You can try XW_CLK_KF3 (at your own risk). That’s the nearest to yours. If anything bad happen, revert back to stock firmware.

      • MHD

        my android version is 2.3.5

        • Sorry, not sure too. You can try the nearest match to yours if you want.

          • MHD

            but which one i can use …?
            thanks for ur attention

            • XW_XEF_KJ2 is the nearest.

              • Yash

                I have galaxy s2 i9100G model I have routed it but a whenever I go to to recovery mode it says update from sd , what do I do , I tried clock work mod from rom manager but I still get the stock recovery menu……..please thank you

  • Faiz

    Hey my kernel is #20
    I flashed Litening ROM with its kernel. So which one should I download? And if anything goes wrong, how do I revert back to stock firmware?

    Thanks in advance!! Your webite is awesome! And are you a Singaporean?

    • Faiz

      Btw my Baseband is I9100XXKH3

    • Litening ROM is rooted by default, right? Hehe… I am Malaysian. 😉

      • Faiz

        Yeap it is rooted by default

        • Faiz

          So what should I do?

          • What do you want?

  • Faiz

    Erm which one should I download? XX_OXA_KH3?

    Thanks again!!

  • wewe

    hey jayce

    First, I rooted my samsung using JPKG5, but decided to change it to XXKG5 by just overwriting it using Odin. Is that OK?
    Also, I flash zImage of XXKG5 and the following messages appear on the screen,

    — Copying media files…
    Successfully copied media files.


    — Updating application…
    Successfully updated application.

    — Applying Multi-CSC…
    Installing Multi-CSC
    Can’t access to ‘/system/csc/DCM/system/’.
    Successfully applied multi-CSC.

    Is this normal? Why I can’t backup my device using CWM? When I’m trying to backup the same message appears. Please help. Thanks!

    • wewe

      by the way which of the two is the latest? Is it JPKG5 or XXKG5? Thanks!

      • XXKG5 should be latest as it is based on Android 2.3.4. JPKG5 is only Android 2.3.3.
        Wipe data and cache first. Then install XXKG5.

    • I did not notice this can’t access issue on my phone. So it is not normal I think. Did you wipe cache previously?

      • wewe

        No i did not, so i will wipe it using CWM and then re-root it with XXKG5 uging Odin. Is that right?

        • You just want to install CF-Root XXKG5 or XXKG5 firmware?

          • wewe

            i already root it to XXKG5 but I did not wipe cache before doing that, then when I try to remove the yellow triangle by flashing zImage, the can’t access message appear

      • wewe

        Or I will just wipe cache, and then re-flash Kernel XXKG5 using CWM?

  • Chloe

    Hi Jayce,

    I’ve just bought Samsung galaxy s2. When I check the Kernel version for the first time, it says:

    well, just like the photo above. Does that mean my phone is rooted? But I have not done any rooting. =O

    I bought this phone from original Samsung distributor.
    Please solve my problem.

    Thank you!

    • Nope, it is not rooted yet. The root word there does not mean rooted… 😛

      • Chloe

        I see! Thanks alot! :DD

        • Chloe

          One more question, according to the above paragraph,
          what does this means? “a modified kernel based original firmware kernel by adding root to it”

          why do they make a modified kernel version? 😛

          • Because you can’t root original firmware. 😉

  • wewe

    hey jayce,

    i return my kernel version to OMKG5 by installing it using Odin, do I need to flash the stock kernel XXKG5 or i dont need to do it anymore? and also, can i upgrade it to XXKH3? is this the latest firmware? thanks!

    • Why do you want to flash stock kernel XXKG5?
      Yes, you can upgrade to any firmware you like. XXKH3 is the latest Europe firmware so far.

  • maulik bhindi

    • Are you using XWKF3? If yes, try XW_CLK_KF3.

      • maulik bhindi

        • Please use PC to download it.

        Kind Regards

        • XX_OXA_KH1 is the nearest to yours.

          • Burhan Motiwala

            Thanks buddy. Will root the device and let you know with the results.

          • Burhan Motiwala

            Hello Jayce,
            A small Question ? If i choose XX_OXA_KH1 as you recommended, how would it be different than the orginial one which i currently have (kernel ?? I just want to know in what terms will it be different than the original one ?


            • Sorry, no idea on the detail. You need to refer to the developer. 😉

    I did not succeeded to install CF Root wit Odin on my Samsung Galaxy S2

    The process stuck of faze named Zimering

    My full kernel version is


    Pleas advice

    • Which CF-Root did you use?

      • Gidon

        the one on your web site XW_CLK_KF3

        • Gidon

          Is it the right version?

          Can I send to U by mail a snape shot of the error message?

          • Yes, it is the correct version.

            Is your phone in download mode?

            • gidom


              • Hmm… I also have no idea for the moment. Maybe you can consult the developer at XDA.

                • gidon


                  I did it what was missing is the setting the USB conection to debug mode

                  Maybe U should add this step to your guide

                  But not I can’t access to my mobile ad a disk

                  What should I do next in order t o install a new frameware?

                  • So you manage to instal CF-Root in USB debug mode? I thought USB debug mode has nothing to do with it?

  • arlscl

    Hi my kernel is UHKE1 (chile) which modified kernel should I use, If there is no one, what is the latest firmware so I can flash it in my phone.
    many thanks.

    • You can try XXKG5 firmware if you want.

  • b

    I have kernel which firmware should I use to flash that?

    Thx in advance!

    • Sorry, I am also not sure. But you can install other region firmware and apply CF-Root then. Eg, XXKG5 firmware and XX_OXA_KG5 CF-Root.

  • igor

    Hi my kernel is BOKG2
    which CF-Root should I use?

    10x u very much

    from macedonia

    • Sorry, I am also not sure. You can try XX_OXA_KG2 if you want.
      Or you can install other region firmware and apply CF-Root then. Eg, XXKG5 firmware and XX_OXA_KG5 CF-Root.

      • igor

        even if my phone is t-mobile branded?

        • I read post that you can debrand and install other region firmware.

  • chuan

    Hi, i’ve got a XWKF1, same as your! I’ve downloaded the XW_OJW_KF1 file like you did and used odin3 but it keeps on failing. Any reason why?

    • Based on the installation guide, which step did you fail to continue? Any error message?

      • chuan

        hey it’s alright I’ve got it sorted out!

        it was a serial com port not being recognised or something like that. I read some forums and i changed USB port and restarted my computer and it works fine now!

        Thanks so much for the help and the quick reply!

  • sumit

    u made my day …. i installed one incompatible kernel and u have corrected it thanx buddy

  • ilham

    mine are DXKG3 and i theres none there like mine ..

    • You can try XX_OXA_KG3 if you want. 😉

  • john

    i using DXKH2, which one is mine?

    • You want to install XXKI3 firmware or just root your current one? The nearest to DXKH2 is XX_OXA_KH1.

  • farouk lorenzo

    hi, I have galaxy sII with DXKG3 what should I use for rooting this firmware? thanks a lot jayce

    • XX_OXA_KG3 is the nearest to yours.

  • farouk lorenzo

    ow thanks a lot jayce….quick reply btw..:)

  • raees

    hey there. im using galaxy sII with XWKDD. is there a suitable CF-ROOT for it? i cant seem to find it. thanx.

    • Sorry, not sure which one for you too. Maybe you can upgrade to latest firmware first and apply CF-Root then.

  • SheeP-y-y

    My Kernel version is se.infra@SEI-22 # 2 with DZKI1, which CF-root i shall use?I just updated my s2 to the latest firmware with Kies today.

    • Yours is GT-I9100G? If yes, don’t use anyone of them. They are for GT-I9100 only.

      • SheeP-y-y

        Oh, thanks

      • andre

        hi jayce, for those with a GT-I9100G phone? what can they do?

        • Install pre-rooted kernel that developed for I9100G. You can get it from XDA website.

  • Yoki

    Mine 1 is DXKI2, which 1 should I download?

    • Not sure too. CF-Root is developed for Europe firmware mostly. But you can try the nearest match to yours if you want.

        If root wrongly what will happen? The phone will become brick? so the nearest for me is CE_XEN_KI2 right?

        • You need to restore to stock firmware. I don’t think it will brick, so far did not hear people brick their phone by installing CF-Root. Yup, CE_XEN_KI2 is the nearest.

          • Yoki

            Restore to stock firmware mean after failed to root? I am so blur now, haha.

            • Back to stock firmware if anything wrong happen like boot loop –

              • Yoki

                I don’t have usb jig…. is there have any alternative solution?

                • USB Jig is not a must. It just use to reset the custom flash counter and yellow triangle.

                  • Yoki

                    I just upgrade my phone to the newest firmware which is DXKI2. From your other post, I see that you mention that DXKI2 cannot use USB Jig anymore. So, if I plan to buy a USB Jig, what should I do so that to make it usable? Thanks.

                    • You need to install old bootloader.

  • Yoki

    ok, thanks~~

  • Wilf

    I have:
    Kernel Version #2
    BaseBand I9100XXKI1

    What kernel version would I download?

    • XW_NEE_KI4 should be the one for you, right?

      • Wilf

        Thank you

  • Little_Devil

    I have S2 with these information :
    Baseband version: I9100XXKG5
    Kernel version:

    so I am supposed to use CF-Root-SGS2_XX_OXA_KH1-v4.1-CWM4 , right ??
    or should I use another one ??

    • Yup, that’s the nearest. You can ask Burhan Motiwala who has the same kernel. See it works or not…

      • Little_Devil

        Thank you very much ,, I hope Burhan Motiwala can responde to this comment and tell me the results 🙂

    • Little_Devil

      It worked correctly without any problem 😀 but another question about the binary counter , what is it and is it necessary to reset it ,, I used your guide to remove the yellow triangle and also worked correctly. so now just asking about the binary counter.

      • It is just a counter for Samsung to track how many time did you install custom firmware. It is nothing from user stand point.

  • Roy

    I have,


    which one do I need ?

    • XWKDD is an old firmware. Try upgrade to latest firmware first and apply CF-Root.

  • Robert

    Joyce am using which one do i need ?

    • Sorry, I am also not sure. You can try XX_OXA_KG2 if you want. Or you can install other region firmware and apply CF-Root then.

      • Robert

        Cheers for that Jayce it worked fine now rooted

  • @Jose Luis: Install official firmware will remove yellow triangle. You can upgrade through Samsung Kies if you are using official firmware now. Else Odin or CWM is the only to install firmware.

  • Adload

  • william

    MY S2 has kernel version I9100DXKI2-CL564948. Is it possible to get a cf root for my phone? Please help.

    • Yes, you can try the nearest match to yours. CF-Root is developed for Europe firmware mostly.

  • miikka silander


    My samsung s2 wont restart or go into recovery it just shows the samsung galaxy gt9100 and turns off what shoud i do?

    • May I know what had you done until you got this issue?

  • Elton81

    erm.. i used lightning rom to root.. and now i cant see which kernel version i am in.. it says ninpo@titan #20 … so which kernel should i use to remove the yellow triangle?

    • Use USB Jig. Better don’t use CF-Root as it might mess up your ninphetamine custom kernel.

      • Elton81

        thanks for the fast reply 🙂

        so i just get one from ebay? or is it available in handphone shops?

        • You can try to search at local shop. But I got mine from eBay because I can’t find one locally…

  • paradisawy

  • Naz

    my hp wont turn on after u know how to solve it?

    • What had you install?

  • assaf

                no 🙁

  • Dennis

    Hi Jayce,

    I have a stock firmware DXKI2. Understand that there isnt any CF-root for KI2. What do you recommend i should do to get my samsung galaxy S2 rooted?


    • Try the nearest match to yours.

  • Yoki

    Hi Jayce,

    I would like to ask if my phone ia rooted, can i still update it via kies? Thanks~

    • I did not try it personally, but others said can.

      • Yoki

        ok~ thanks~

  • sam

    hi this mean root?

  • Ezei

    Hi there,

    What is the nearest to DXKI2?
    it is CE_XEN_KI2

    • That’s the nearest match. But I did not test it myself.

  • mike

    What’s the nearest to ki1

    • Look at other comments… 😉

  • Jonathan


    My kernel version I9100DXKI2. Can i upgrade to the latest firmware?

    • DXKI2 is the latest official firmware for your region.

  • jon

    mine is a DXK12 what is the correct Kernel for me?

    • No actual match. You can find the nearest.

  • jon

    Hi Jayce,

    looks like I9100DXKI2 has a bug. My wifi won’t work.. It’s been working for 3 days but it suddenly stopped working and my MAC address shows it’s unavailable. Any suggestions on what my problem is?

  • jonathan

    That mean the nearest one could be CE XEN KI2 for DXKI1, right?

    • That’s the nearest.

      • Jonathan

        Thanks. Appreciate

        • Jonathan

          jayce, hv rooted s2. Question is. It is ok to update the software? Via about phone software update.

          • Rooted is okay. But you will loss root access after upgrade to new official firmware. You will need to root it back.

    • hin

      jonathan.. i got the same dxki1….did that work for u ?

      • jonathan

        Yes.. it works for me

  • jayce, am a newbie to the android operating system.
    my kernel version is XWKDD with a DXKI2 gingerbread build
    been following the instructions and can’t seem to root the phone, it always hangs halfway at during the superoneclick process. please help!
    which CF root should i use?

    • I don’t have SuperOneClick guide here. How can you hang with it?
      There is not exact match for DXKI2. CE_XEN_KI2 is the nearest match to yours.

  • keiron


    Just upgraded my phone via Kies, and have the following;



    Kernel se.infra@SEP-78 #2

    Can’t figure out which CF to use… looking for a ZS KI3 one – can only see XX KI3 and XS KG*


    • CF-Root is developed for Europe firmware mostly. So you can’t find exact match for most Asia firmware. But you still can use the nearest match to yours.

  • Keiron

    So which one do you recon?

    • I did not test ZSK13 with CF-Root myself. So you need to make the decision yourself. 😉

  • Keiron

    I can reset to stock if it goes bad can.t i?

    • Yes, as long as you still can load bootloader (SGS2 Logo).

      • keiron

        ? Don’t know what you mean there. so there is a chance I will brick my phone??

        • That SGS2 Logo when you start your phone is the bootloader. If you brick your phone, you can’t see that.

          • keiron

            All good – used XX_OXA_KI3 and it rooted just fine! Damn good to get rid of those ads again!

  • M3TaMoRPHoSiS

    my kernel version se.infra@SEI-22#2
    build number GINGERBREAD.DZKI1..
    Which should i use?

  • thl6366

    my samsung s2 is in kernel version se.infra@SEI-30#2 , or refer to baseband version I9100GDZKH4 ?which should be i download, pls advice, thanks

  • Iain

    my Kernel is I9100DXKG4

    Android Version 2.33

    Which firmware should I use?

    • There is no exact match for DXKG4. Use the nearest match to yours if you want.

      • Iain

        is that what you would recomend or is there another method I should use?

        • Yes, CF-Root is the easiest way to root. It also add CWM, BusyBox and SuperUser for you. You can search for other root method as well.

          • Iain

            what problems might occur from using an incorrect kernel?

  • Chia

    Hi…the XW_OJV_KF1 link is direct to wrong file. Please help. Thanks

  • Rednaxela

    hello jayce

    my kernel is xxKI4, which one will i use XW_NEE_KI4 or XX_XEO_KI4? need your advise thanks…

    • Rednaxela

      =)) already solve my problem… (read first before ask) hehehe

      thanks your blogs really helps

  • KS

    Hello Jayce,
    I guess I used an incorrect kernel, need your advise, thanks…

    Here is the information..
    Baseband version: I9100XXKI4
    Kernel version: se.infra@SEP-62#2
    Build number: GINGERBREAD.ZSKI3


    • What is your problem?

      • KS

        when i flash a custom rom, boot loop is happening..

        • Just wipe data and cache in CWM then.

  • KS

    besides, i wanna know which CF-Root should I use? XXKI4 or ZSKI3? Thanks!

    • Above firmware is your current one before install CF-Root?

  • KS

    no, but is there anyway to check the preload one?

  • Rednaxela

    hi jayce,

    how can I remove the yellow triangle on start? need helps please thank you.

  • Sevenfold

    Hey Jayce,

    Great tutorial !!

    I have question bout the kernel version,

    Baseband version : I9100GDZKI1
    Kernel Version :

    What version should i download it ?


    • Don’t use any one here. Please refer to this guide –

      • Sevenfold

        Thank Jayce,

        its so easy to do the root but now i got problem, my phone wont detect wifi 🙁

        • I don’t have I9100G. So can’t test it myself. Try to ask others at Lowyat or XDA see.

  • xmood

    I got DXKG3 ,pls find out my match 🙂

  • keiron

    For those people that keep asking which Rom they need, the following information will help;

    The K stands for the year – K is 2011
    The next letter stands for the month – eg – G is July (7th letter of the alphabet)
    The third part is the number, and is the release number.

    For example, my one was KI3
    KI3 = 2011 September Release 3.

    The first letters are the location ones

    So I had ZSKI3, meaning I had a Hong Kong Rom, September 2011 release

    I rooted to XXKI3, so changed the country, but kept the release version. As I understand it this is the ‘KI3’ is most important bit, but i am not an expert and stand to be corrected on that

    Hong Kong/Taiwan roms (ZS) are compatible with all international versions

    • shwe

      hey man my kernel version is

      which insecure kernel do you think would be the most appropriate/enhance performance the most?

  • jaski

    hi i know some one already aked this.
    what comptible root should i get. i have dxki2?? tnx im planing to root my phone had only for a week. hope you can helo me. dont want to mess up

  • jaski

    got it already got to use nearest.. so that would be.. ce_xen_ki2!? right?? what will happen if i use ki3 on the list .. just wondering?

    btw. good job for the guides help me understand a lot

    • You should be able to use either one of them if the kernel does not different much with yours.

  • shwe

    Hey JAYCE

    my kernel version is

    which insecure kernel do you think would be the most appropriate/enhance performance the most?

    • CE_XEN_KI2 is the nearest match to yours.

      • shwe

        hey man thanks so much for your help but would it be ok to use the following kernel?


        thank you so much. this blog is amazing.

        • XWKE7 kernel looks old on your UHKI2 firmware. Better no.

  • shwe

    i downloaded the CE_XEN_KI2 kernel however when i unzip it, it shows up as a zimage file. is this the same thing as a .tar file to load onto using the cf root method?

    • Use 7 Zip to unzip. Yes, it is also CF-Root kernel.

  • Charles

    Hi Jayce,

    I’ve recently using Odin to load the Litening Rom into my SGS2 from original XWKF1, now the infor as below –

    Baseband – I9100XXKH3
    Kernel Ver – #20
    Build Number – Lite’ning Rom v6.1 XXKH3

    How do I install the ClockworkMod (CWM) in order to try other Roms?


    • Lite’ning Rom has CWM. Just boot to it.

      • Charles

        Hi Jayce,

        For Lite’ning Rom 6.1 there was no CWM apps added, I googled it and some users find same problem as this too, could I straight downgrade it to Ver 6 or 5 from 6.1 by using Odin?

        Would like to test that out as this Ver 6.1 eat the batt pretty much for my user experience.

        Thanks for your reply.

          • Charles

            Hi Jayce,

            Noted with thanks.

            By the way for the question of the Lite’ning rom, can I just use Odin to flash the Rom to lower version, as I’m currently using Ver6.1, can flash back to Ver 5 directly?

            Sorry for the trouble as this is the very first time I Root and lite’ning is the first I tried, haven’t got myself a SD Card yet so couldn’t try the CWM root for other roms which requires it.

            • Yes, just wipe data and cache with CWM before downgrade.

              CWM uses internal sdcard. No need external SD card.

              • Charles

                Hi Jayce,

                Thanks, I’ve followed the instruction and now installed the Leomar75 Rom via CWM, just one last question, for firmware of 2.3.4 going to 2.3.5 or higher is no problem, but if I currently running on 2.3.5, can I just flash the rom to a lower firmware of 2.3.4 using CWM?


                • Yes….

                  • Charles

                    TQ Bro! 🙂 now checking out the Checkrom Rev v2 XXKI4 😛 looks good

  • Ramil

    Good day to you Jayce! I hope your doing fine! I would just like to ask if I am encountering Force Closes in running my applications does that mean that something is wrong with the configuration of my samsung galaxy s2 or the combo of my chosen rom & kernel does not match. Should I reflash or do a hard reset? Please guide me to what should I do with my celfone. Is doing a hard reset many times bricks the phone? If you don’t mind me asking what is your chosen rom and kernel for your samsung galaxy s2. I am having a hard time finding the right and stable firmware and kernel to use for my celfone. I hope you can help me. Thanks in advance! God Bless!

  • Kragus

    Hi. I messed up my phone a lot, i’m a noob in this, so i tested and learned a lot with many risks. Now i got at a point in wich i don’t know what to do. Okay, so i want to get rid of the yellow triangle, BUT…My sg2 says the folowing:
    Android vers. 2.3.3
    Baseband vers i9100xxke7
    Kernel vers.
    Build nr. gingerbread.xwkf3

    As you can see none of them match, i got a mix of ke7 xdd and kf3, wich cf root i use??

    • My advice…
      Install a full firmware (without mixed) like XXKI4. Then root it with CF-Root XXKI4. Easier…

  • Kragus

    Thanks for you attention. I’ve just downgraded from ki4 because i had some usb problems :)), i strugled for two days to get rid of ki4 cause my pc would not regognize my sg2 in download mode, sayd “unknown device” or “the usb device malfuntioned”. Finaly it worked and installed another firmware (kdd), but after posting my question to you i installed kf3 and works just fine, i followed your video. By the way, that’s how it all started, i was following your video and my pc would’s see the phone :).
    Another question, if i’m not bugging you, a week ago i have no ideea what i did, but my phone booted to the language screen with the green android, it says to choose language anf tap the green guy, i tapped it but nothing happened, rebooted restarted and nothing, i assumed it was blank so then i installed a random firmware and it worked. How can i do that again? remove EVERYTHING from it and reinstall all fresh. i have a vague ideea that my firmware is all f**ed up, works fine though. Ihate the ideea that all is messed up inside (i think) And…does xxk14 have some compatibility issues or something? cause i bet all new stuff has it’s bugs and i prefer something older. Like, shoul i get the 2.3.4 or 2.3.5 or stivk to 2.3.3?
    Huh! That was a lot 🙂

    • Did you wipe data and cache with CWM when install new firmware? This will make your phone to have a fresh start.

      I have been using XXKI4 custom firmware. No issue so far. And performance is great too.

  • Kragus

    I’ve wiped data and cache but in recovery mode default of the phone, i read in a lot of places abot CWM but i haven’t quite undertood this. So i gues i haven’t done it with CWM. Still learning

  • Kragus

    I found a “Clockwordmod recovery”, is that the one? or no recovery?

  • jaski

    hi, once again i have a question, how to download cm7 on my s2. what is needed and requirment i only hve 2.3.3 fw.

  • Kragus

    WooHoo! Done, succesfully installed CWM. One problem, i forgot what i was trying to do in the first place :))) after so much searching on forums got my mind messed up, now i need a recovery :)) Thanks for the help Jayce, you’re the best!!!

  • Kragus

    One more noobie question. I did a fresh flash, all brand new, my kernel and brand (gingerbread) are xwki4 but my baseband is xxki1. Is that good? Everywhere i look on forums they all match, mine doesn’t. What have i done wrong?

    • Baseband different is okay. No big issue.
      Did you wipe data and cache? And are you using official XWKI4 firmware (not custom firmware)?

  • Kragus

    I wiped everything, davlik cache, data, batery stats – everything…and yeah, i think it’s custom, dont’t remember where i got it from, followed some links fom here though

  • Kragus

    Sorry, actualy i got the xwki4 from xda – so i gues it should be official

    • Correct then. Phone == XXKI1 in XDA. So no issue.

  • Kragus

    Thanks a bunch. Whatever they pay you, it’s not enough 🙂

  • Tazmaniax

    • XXKI4 has direct match. Just look for KI4 first, then XX.

  • Guys mine version is I9100XWKF4-CL280512 root@dell151#2 which kernel I should use from these ones because KF4 is maching but XW not I am litle bit confused please help.

    • Not all the firmware has perfect match for CF-Root. So you need to use the nearest match sometime…

  • Jonathan


    I’m trying to remove the yellow triangle. What is the nearest kernel for I9100CEKI2-CL586309root@DELL147 #2

    • CEKI2

      • Jonathan

        I cant find CEKI2. Do you have a link?

        • Jonathan

          Jayce, Which CF root i need to download? Can i download the CE_XEN_KI2 inorder for me to remove the yellow triangle?

          • You need stock kernel to remove yellow triangle.

          • Jonathan

            Thanks Jayce,

            What i mean is inorder for me to remove the yellow triangle i need stock kernel which is same as the current kernel is CEKI2, right? My question is which CF root should I use? Can I use CE_XEN_KI2 for removing the yellow triangle for kernel CEKI2?

            • Yes. CE_XEN_KI2. Yes.

              • Jonathan


                Finally… the yellow traingle removed.. thanks for the step by step tutorial.. Cheers

  • Pieter

    i have i9100xwki9, witch one do i have to take?

  • Bryan

    Hi, does it matter if my kernel version doesn’t tally with my baseband version? My kernel version is DXKH2 whereas my baseband version is DXKH1, so I should use the one for DXKH2 which is XX_OXA_KH1 right?

    • No problem if baseband does not match with kernel. Yes, XX_OXA_KH1 is the nearest to yours.

      • Bryan

        Ok so it should work for my I9100 right?

        • I did not test it personally. But I think it should work.

          • Bryan

            Ok, it won’t brick or something like that right?

            • I did not hear people brick their I9100 with CF-Root so far…

              • Bryan

                Hey TKS! I have my device rooted:)

  • justin

    My code is BO-KG2 what should I use please???

    • You can try XX_OXA_KG2 if you want. Or you can install other region firmware and apply CF-Root then.

  • ku123

    what about KDD ?? Any idea ??

    • ku123

      also my kernel version is root@DELL 103 #2. i rooted my phone last night n i jus wanna get rid of the yellow triangle.

      plz lemme know how it can be done n which cfroot will be required??

      • CF-Root does not have XWKDD version. Try to upgrade to newer firmware. Then install CF-Root. Else get yourself a USB Jig.

        • ku123

          can you suggest which firmware should i use ?? you seem to have a lot of knowledge in it 🙂

          • I am using XXKI4 firmware right now. You can try it if you want.

  • ku123

    can you plz send me the links of both the firmware n cfroot download. your already using it right.
    sorry for the trouble !!

    • Links are in the post. Take your time to find it…

  • ku123

    is the xxki4 file 255mb ?? and also the cfroot will be the XX_XEO_KI4 right ??

    • I think so. Yes, CF-Root XX_XEO_KI4 is the one.

  • ku123

    iv downloaded the files. jus wanted to know if i should flash a similar kernel version before flashing the firmware using odin ??

    • No need. Just install the firmware directly.

      • ku123

        then why have you mentioned to check the kernel version before flashing new firmware ??

  • Hi jayce which root file should i down load for my version dxki2 as i wan to root my sgs2

    • Please refer to my reply above…

      • Hi jayce whichh reply:) i not sure whichroot files

        i need to use fordxki2

        • Just use the search function Ctrl + F. Then find DXKI2. 🙂

  • dev

    i wanna download the xw_clk_kf3 firmware but the link is not working…its redirecting me back to the homepage

    • Which browser are you using on your desktop?

  • ku123

    iv flashed it jayce.. but the yellow triangle is back.. can i still get rid of it even though iv rooted my phone ??

  • ku123

    which file are you extracting ??

    • CF-Root kernel of course.

  • Yuehan

    hi Jayce,

    I tried to read most of it above but I think I didn’t find mine. I have rooted several times but always lost wifi. I am in China and have a Galaxy S2.
    Kernelversion:; se.infra@SEI-26#2. Gingerbread ZCKJ1.
    Do you have an idea how to root this one and also keep WIFI??

    • Sorry, I have no idea. Never face Wi-Fi loss issue when using CF-Root kernel.

      • Yuehan

        Do you think I can try XW_LUX_KJ1??

        • Not sure CF-Root kernel can work on China SGS2 or not…

          • Yuehan

            next week I go to Europe. what should I do to fix it there?

            • No idea, I am from Malaysia. 😉

              • Yuehan

                Ok, thanks I will ask in Europe what the possibilities are.

  • hi jayce

    i root my samsung gs2 and install lighting rom6.1 to the phone but now i cant sms chinese word .is there any idea to text chinese for root user

    thank u

  • rushdy

    i9100xwkdd? how i get cf-root for my phone?

    • CF-Root does not have XWKDD version. Try to upgrade to newer firmware. Then install CF-Root…

      • rushdy

        this my kernel version… … i can upgrade my firmware…i dont know…pls…

  • rushdy

    i want to remove yellow triangle…

    • The easiest way, get yourself a USB Jig.

      • rushdy

        after i watched your vdo…i followed you step by step…now i already got I9100XWKDD_Kernel…no i want to extrct this file by 7-zip..but it asks for password…what is the password?

        • The password should be there at the website you downloaded that kernel.

        • rushdy

          what is the password after extrcted stock kernel by 7-zip

  • rushdy


  • rushdy

    how i can get cwm manager…i can use another software..becoz i cant find it at android market

    • rushdy

      please my friend…it only last step..

    • It comes along with CF-Root kernel.

  • Gary

    So which one should I download if mine is DXKI2?

    • Hi Gary, there is not exact match for DXKI2. CE_XEN_KI2 is the nearest match to yours.

  • john

    my phone also DXK12…it can use with CE_XEN_K12?

    • Some said okay to use. But I did not try it personally.

  • Mine is not listed here mine is I9100MUGKG2 can you help?

    • Sorry, I have no idea can CF-Root work on I9100M or not. Please consult others who have the same kernel at XDA see.

  • Karthik

    Hello I have messaged you many times. Please I beg you. Please reply I need your help ..

  • praks

    bro, its asks for username nd password veneva i try to download d req kernal type…

    • No username and password required to download CF-Root kernel here. Did you download it with PC?

  • Leslie

    Hi. Jayce if I want to install the latest firmware like XWKK2 2.3.6 by using Odin. Then did I still need to Root my phone or install clockworkmod before it ?

    • No need. You can install XWKK2 firmware with Odin directly. Root it if you want later…

  • kragus

    Hi again. With these cf-roots i can root no matter if i have 2.3.3 2.3.4 or 2.3.5 etc?

    • Yes. But better get the exact match.

      • kragus

        Thank you. i did it and it worket like a charm. one more thing, i also have a galaxy s1, it is coded in the operators network, besides losing waranty (wich i don’t care about) If i change the firmware, fresh install and root, will it be decoded? i mean besides paying 40E to decode, can i decode it by custom firmware?

  • Alvin

    Jayce , my kernel version is se.infra@SEI-22 #2 and I9100GDZKI1 . Need download which CF – Root . Pls reply ty .

    • G version can’t use CF-Root. Please refer to this guide –

      • Alvin

        Uhmmm… I followed to the link but after I’m in Odin Mode , the computer asked me to install Samsung USB Drive thingy but failed to install it . I opened the Odin3 , all the box was empty . Is this related to Samsung USB Drive ?

        • It need USB drivers. Do you have Samsung Kies installed on your Windows?

          • Alvin

            Soooo the problem is I lack of Samsung Kies on my Windows ? Ty for your information , Jayce . I just need to install it and the problem is solved ?

            • Should be…

              • Alvin

                Another problem , the link you gave me worked . But where is CWM Manager ? I only got SuperUser only .

      • ajay upadhyay

        hey if ill root my s2 will my imei flash plz reply

        • CF-Root won’t touch IMEI.

  • Addy

    Jayce i have downloaded correct cf root file for my s2 but when i extract it itshows zimage file

    • Use 7-Zip to extract.

  • KimTaeng

    Hi! I also get the zimage file even when I extract using the 7-zip program. Could you advise me on how to get it correctly?

  • KimTaeng

    Hello again. I figured it out already. Thanks!

        • Hmm… I have no issue to extract it with 7-Zip. What unzip did you use? Try 7-Zip see.

  • vladimir jirecek

    I’m from Europe
    I’d like to root my samsung galaxy model GT-19100
    my baseband version ist I9100BUKG1
    my kernel version root@DELL102 #2

    which from yours would be the right for me?


    • I am also not sure. You can try XX_OXA_KG2 if you want. Or you can install other region firmware and apply CF-Root then. Eg, XWKK2 firmware and XW_XEN_KK2 CF-Root.

  • MeHDi

    hi jayce;
    im using xw-kk2 official rom and want to install xw-kk5 2.3.6 deodexed
    for install from ClockworkMod Recovery mode i should use XW_XEN_KK2 CF-Root?

    • Yes, MeHDi.

      • MeHDi

        Tnx, Jayce

  • kragus

    Hi Jayce! Small come-back. i have the 2.3.5 XKI4. As normal as it should be, my phone gets hot durring diverse activities, using intensly CPU and Graphics (Ex: portal game). I read on xda i think, not sure, that KIx has that issue, gets hot fast. They suggest using other firmwares. You know anything about this? Any idea? Is it true? I know it’s normal to get hot, but… it’s hoter than usual

    • Nope, I have no issue on XXKI4 firmware. It does get warm when play 3D games. But still consider normal to me when compare to other firmwares that I have used.

  • Hi Jayce,

    My Kernel is XWKE1, I cannot find the matched version. May I choose XW_XEU_KE2?


    • That’s the nearest match.

  • octav

    Hi, Please help me I’m ready to root now, and I have version

    Kernel Version:

    Which version from the 3 that contain KG2 should I use ?

    • You can try XX_OXA_KG2 if you want. Or you can install other region firmware and apply CF-Root then. Eg, XWKK2 firmware and XW_XEN_KK2 CF-Root…

      • octav

        Hi, thanks so much for your response, I just updated with official Samsung firmware, using Kies, and now I’m runing…:

        Kernel Version:

        so i guess I can use “”
        since this is the only one containing KJ3 ?

        • octav

          I just rooted now using that CF-Root and it works wonderfully thanks Jayce for your great guide !!

  • lopers1022

    hi i already have cf root ke2 but i want to update to a newer version because i read that, theres a new cmw vs 5 and mine its vs 3 so wich kernel do i shuld download.

    my android version is 2.3.6

    base band xxKI4

    kernel version xwKE2

    revolution ROM

    • I don’t think there is CF-Root with CWM v5 for XWKE2 kernel. You might want to upgrade to latest firmware which use CF-Root with CWM v5.

  • kragus

    Hello again! I see two methods of rootin (there may be more) but… using CF-Root and Superoneclick wich requires an insecure kernel. I i use cfroot i don’t have to do the superoneclick, right? Or am i rooting wrong, using cfroot. Does it even matter wich way i root it? Your method worked great till now, superoneclick is…some clicks extra 🙂

    • No need to use SuperOneClick once you installed CF-Root kernel. For rooting, either way is also okay. But SuperOneClick does not give you CWM.

  • Kareem

    my kernel version is can i use this CF-Root XW_XEF_KJ2 cause i didnt find any CF-Root that match both JP and KJ2


    • You can try it if you want.

  • Lim

    Kernel version root@DELL129#2
    Which version should I use?

    • CE_XEN_KI2 is the nearest match to yours…

  • Natalie

    I’ve checked many websites but none have my Kernel Version, please help!
    It is
    Thanks 🙂

    • Your SGS2 is I9100T, right? Not sure CF-Root can work on your SGS2 or not. Please ask others who have the same model at XDA to double confirm.

  • @Alvin: Download it from Android Market.

  • Abasin Azad

    Dear Joyce, Greetings & Thanks for your time & support you provide to the World..
    As few months ago I had tried your instructions by installing MIUI on HTC HD2… it worked well… so this time I went to upgrade my Galaxy s2 with ” GT-I9100_XEN_I9100XWKK2_I9100XENKJ1_I9100XXKI4\GT-I9100_XEN_I9100XWKK2_I9100XENKJ1_I9100XXKI4.tar.md5″… but it failed after several times trying again & again…now my mobile is totally dead with the black screen… I use oden 3.v1.85.. as reffered by you… it fails almost after 80 % of progress.. at the end it says.. All threads completed ( Successful = 0/ failed 1 ) …
    Unfortunately I did not copy the Kernel information of my mobile as well so I could install some other version… as MIUI for which I need to install some other thing.. can you kindly advice ?

    • Can you still load Odin download mode? If can, try to install other firmware see.

      • Abasin Azad

        Thanks Jayce ! yeah I can load Odin & tried to installed below ..

        PDA : CODE_I9100XXKG2_CL375027_REV02_user_low_ship.tar.m d5,
        PHONE : MODEM_I9100XXKG2_REV_02_CL1037208.tar.md5,
        CSC : GT-I9100-CSC-HOME-MULTI-OXAKG2.tar.md5

        Using below link

        But almost after 90 to 95 % completion.. it said.. it is failed.. now when I restart the mobile it says.. ” Firmware upgarde encountered anissue. Pelase select recovery mode in Kies & try again…”

        Please advise !

        Thanks for the prompt response !

          • Abasin Azad

            Dear Jayce, Do I need to know the kernel version ? which I don’t have ?

            2nd in the link provided above.. there are so many version & links.. which one you advise.. sorry for keep asking !


            • Your SGS2 model is I9100, right? You can try XWKK2 firmware.

              • Abasin Azad

                Thank you dear Jayce.. After installing the above firmware again at the end it said.. failed.. so after that I installed the kernel using the PDA option & thus finally the mobile came to life…. Thanks dear for your kind support & guidance.. I really appreciate it !

  • Sid


    Thanks for the guide. However my Kernel is a BVKG2 (from orange France). Can you tell me which one I should use or if I should use another solution?


    • I am also not sure as there is not exact match. You can try any KG2 CF-Root if you want.

  • Sid

    Thanks for your reply. Is there any risk attached to the operation (i mean fatal risk, like bricking) or is there just possible lost of data?


    • Yes, it might brick but so far I did not hear anyone brick their SGS2 I9100 after installed CF-Root.

  • dwight

    Hi Jayce, Im new to Samsung Galaxy S2 just bought it 3 weeks ago, I just did the root on my phone with XWKG3 and it worked fine came with the superuser and CWM apps like you said. The reason Im doing this root is because I wanna remove bloatware from OPTUS not sure on how to go about doing this? Any help would be much appreciated. I tried using Root Explorer App before but it doesn’t allow me to delete Optus stuff.

    Thanks in advance

  • m77m7

    Hi Jayce, I can’t find anything remotely similar to my M250K.

    My firmware is

    any ideas?

  • Frank

    Hello, my Kernel version is #2

    what CF root fits my device?


    • There is no exact match for UMKG4. Use the nearest match to yours if you want.

      • Frank

        How can I flash a different kernel?

        • Installation process is the same. Don’t install CF-Root if you feel uncomfortable. Try other rooting method instead. 😉

          • Frank

            It’s just that I was trying to install CyanogenMod 7.1 and it kept appearing this:
            – Install from sdcard…
            Finding update package…
            Opening update package…
            Verifying update package…
            E:failed to verify whole-file signature
            E:signature verification failed
            Installation aborted.

            Do you know how can I solve this?

            • Are you using CWM to install?

              • Frank

                I tried using ROM Manager.

                • ROM Manager has issue with certain SGS2 kernel. Please consult ROM Manager developer on your issue.

                  • Frank

                    I just sent them an e-mail, hopefully they will tell me what’s wrong. Thank you so much!

  • Hammad

    Hi Jayce,
    I read from top to bottom regarding the Download CF-Root for Samsung Galaxy S2 thread.

    And notice this 2 question you answered in different ways which is the same firmware as mine.

    Zeno says:
    JPKF3 upgrade to JPKG5

    Jayce says:
    Should be JP_XSG_KG5.

    hesam says:
    Which kernel is for jpkf3-cl303619root@dell101

    Jayce says:
    You can try XW_CLK_KF3 (at your own risk). That’s the nearest to yours. If anything bad happen, revert back to stock firmware.

    My SGS2 Info:
    Model Number: GT-I9100
    Baseband Version: I9100XXKF2
    Kernel Version: #2
    Build Number: GingerBread.JPKF3

    My question now:
    1. What is the nearest CF-Root Firmware for my SGS2 Model?
    2. Can I upgrade also from JPKF3 to JPKG5?

    In your personal opinion and knowledge which is the best way for me?

    Regards on your very helpful website.

    • 1. XW_CLK_KF3
      2. Yes.

      Best way to do what?

      • Hammad

        So I can upgrade mine using JP_XSG_KG5?

        What is the difference between XW_CLK_KF3 and JP_XSG_KG5?


        • I think so.

          No idea. You need to consult CF-Root developer for that.

  • Hammad


    I try to download the Official I9100 Firmware from

    The filename is GT-I9100_XSG_I9100JPKF3_I9100XXKF1_I9100OJPKF2

    It’s near to to JP_XSG_KG5 only the JPKF3 is different, but still I don’t know which path I will take if I upgrade to JP_XSG_KG5 or use the nearest XW_CLK_KF3?

    If you have my SGS2, what path you will take? 🙂 I just want to hear from the expert


    • I will use XW_CLK_KF3 on JPKF3 firmware.

      • Hammad

        Thank You for you advice Jayce.

        I will do it later, then I will post what happen so other poster with the same question can refer with this regarding Kernel Version: #2

        • Hammad

          XW_CLK_KF3 works perfectly on I9100JPKF3

          Thanks Jayce

  • Hammad

    Can I add another question:

    How can I know my SGS2 Info regarding this:


    Is there a option from the Phone to see this information?

    • Dial *#1234#

      • Hammad

        Thank You 🙂

  • Hi Jayce,

    I have
    baseband I9100XXKF1

    Do you know where I can find Insecure/Original Kernels?

    many thanks,

  • Lance

    Same issue here, trying to see what kernel to use. My about shows;

    Any help is appreciated.

    • Your SGS2 is not I9100, right? Then, you cannot use CF-Root.

  • j

    i ant find the I9100XWKDD kernel version !

  • Erick

    Does rooting your SGS2 will affect your phone’s warranty?

    • Yes, Erick.

      • Erick

        Oh I see. What can I do if I rooted my phone and I need to claim my warranty?

  • Frank

    Hi, this is the way to root my device right? I have to use odin to root my phone?

  • Alonso

    Hi Jayce – tremendous thing you have here my friend!!! Got 3 days reading several posts.

    this is mine: – i9100o UHKI6 – CL614783 se.infra@SEi – 45 # 2.

    band base i9100UHKG4

    Gingerbread 2.3.5 (after run original update from 2.3.4)

    So, this is the deal.

    1. what CWM can I install?
    2. Considering Litening 6.1 – will it be good to proceed after the proper CWM installing?

    thanks a lot – all of your knoweledge is greatly appreciated Greetings from Costa Rica.

    • 1. Get the nearest match.
      2. You can install Litening 6.1 directly without CWM.

      • alonso

        And the nearest match would be


        or anyone that ends on KI4 ?

        what to consider as a priority in this case?

        • For me, I will choose XX_XEO_KI4.

          • alonso

            Ok thanks a lot..I’ll let you know the result

  • Alonso

    please read – i9100 UHKI6 – CL614783 se.infra@SEi – 45 # 2.

    no ”o” after i9100


  • mickey b

    mine is BuKj3 its not on there what do i download


    • You can try the nearest match like XW_XEN_KJ3 if you want.

      • mickey b

        i followed instructions when i downloaded XW_XEN_KJ3 there was only zimage file and no tar file

        • Hi mickey b, please use 7-Zip to extract it.

          • mickey b

            ok Thanks For you time

            • mickey b

              sorry to bother you again

              ive used every program on the market i think including 7-zip and all i get is zimage and no tar file

              • No idea if you still can’t get tar file with 7-Zip. Mine is working fine as in the video tutorial.

                • mickey b

                  sorry it was me bieng an idiot
                  got it sorted

  • Steve

    Mine is I9100TUKJ1 so which one do I use
    thanks in advance

    • Sorry Steve. I have no idea. You can try to nearest match if you want.

  • shanavas

      • Jeremy

        Hi, thank you very much, I have successfully rooted my phone.

  • Hans

    my kernel version isno avilable i your list.. here is my kernel version..

    • Upgrade to latest firmware. Else use nearest CF-Root match.

  • kragus

    Hello again! I may have a stupid question, but i must know… I know that doing a hard reset will delete almost all user files on my sgs2 like “//mnt/sdcard/” and reset y settings of the firmware. Can i delete ALL files from my sgs2? Imean all from “//…” all from root directory. Just asking…What i acctualy want to know is if i delete all will i be able to go into download mode for flashing a new firmware after that? The reason for this is that i tested a lot of firmwares and custom roms and tiny bits and pieces still remain “hidden” thus i want to erase EVERYTHING! Gonna do it too…

    • Just factory reset it with delete all USB storage option.

  • kragus

    Thanks, i erased everything i could from the root folder with a root explorer. It worked perfectly. I mean now i have a faulty system with lots of force close errors even after factory defaults, but now i can flash a new firmware

    Thank U

    I Install the version from XDA Webstie

    But when I tried to run Back and Restore I get an erro can’t mount SDCard

    Pleas advice

    • Cannot mount SD card from Android OS?

  • gidone

    No when I tried to run CF Root

    Voluome UP Botton + Choose + Power

    • Please consult CF-Root developer. I did not try CF-Root on XXKP1.

  • Hello, so this is my first time rooting. I’ve looked through your list of CF- Root’s, but I couldn’t find a specific Root that would exactly match my SGS2. Kernel Version is I9100MUGKG2
    I’d appreciate it if you could help me find a specific root. Thanks!

    • Hi CO83, I have no idea can CF-Root work on I9100M or not. Please consult others who have the same kernel at XDA website.

  • Jah Youth

    I rooted with the method and I have ROM Manager on my phone which has a Clockwork Mod Recovery option that I tried using, E:”Failed to verify whole-file signature” it hangs on the same message.

    Please advise

    • CF-Root does not work properly with ROM Manager. Please use CWM Manager or boot into CWM directly.

  • Jay

    HI Jayce,
    I just bought Samsung Galaxy S2 and My
    Android Version is 2.3.6
    Base band Version is I9100DXKL1
    Kernel Version is
    root@DELL 137 # 2
    Build Number is GINGERBREAD DXKL3

    So What I need to Download and How I can root my Phone.
    I want to Root my phone because to add some language font to read in Facebook and other application which I currently not able to read. ( I can see some continues square symbols instead of fonts )

    Any Other solution to add Fonts in SGS2 phone ??

    Thanks in advance.

      Get fonts online (Settings – Display – Screen display – Font style).

      • Jay

        Hi Jayce,

        Thanks a lot and i have done it and let me know how i can add some indian language likes Gujarati and Hindi on my SGS2 now ?

        • Sorry Jay, I have no idea. Try to look it at Android Market or Google it.

          • Jay

            Ok No Problem,

            Can you advice me what should i do after successfully rooted my phone and how i can change firmware ..I have downloaded Rom Manager and tried to use it for download and install Rom but after rebooting my phone always failed to install downloaded rom.

            • Root access is not needed to change firmware. Install official firmware with Odin. Or custom ROM with CWM.

              ROM Manager does not work properly with CF-Root. Boot into CWM directly.

              • Jay

                Just today i have faced some problem , my phone was auto restart and after that stop at black screen with yellow triangle and not able to finish loading …I have try to restart many times but not working ..please advice what should i need to do ..?

  • Barry Merridan

    Hi Jayce
    I think i should have used your site first as i now think i have a brick. I bought a galaxy s2 but it had a password in it and was advised to update software, this i did. But now all i get is a keyboard with confirm password and i have used a few trying. I cant get into phone to see kernel etc, so i am looking for your help in solving this. The software was installed through odin and it passed all ok. I am very new to all this and although i am 65 i like to try and keep up, i installed software Gingerbread XWKDD 2.3.3, and EXT4.pit, maybe i needed to clear the cache so the password box would have gone, but i cant get past this password thing.
    Any help you can offer would be appreciated, but please bear inmind it takes a while to sink in, hoping you can solve my brick problem.
    Many Thanks

  • i have XXKL1 WHAT ABOUT IT?

    • Hi praneet, please use the nearest match like XW_INU_KL1.

  • James

    Hi my wifes SGS2 has a Kernel Version

    Following your guild I can see she needs the root for XWKE7.


    however just wondering what the XEU means or why its there?

    A noob question but I have a GNex and this is the first time I have tried to root her phone.

    • XEU is the CSC for that firmware.

  • Matt

    Hi Jayce,
    Seeing if I can bend the guidelines a little here
    I have an I9100TDOKH1, makes sense to use XX_OXA_KH1-v4.1-CWM4
    But can I use XW_XEU_KH4-v5.0-CWM5 ?
    This will give me CWM5 instead of v4.1

  • Tony

    I am from Croatia (VIP network) and have been eager to root my Galaxy S2. Thank you ALL for your input!

        i just use odin and root with but just now stuck in the startup screen and with the triangle sign . what does that mean?

        • Then CF-Root-SGS2_XX_OXX_LP6-v5.2 does not work on XWLP3 firmware. Try to factory reset in CWM.

  • Matt

    Hi Jayce, I now run CM9, but no CWM. There is ROM Manager v5.0.0.6 is that the equivalent to take/restore backups? (I took a CWM backup of my stock ROM before flashing the latest CM9) could I use this ROM manager to make new backups, or restore my stock ROM?

    • CM9 should come with CWM (boot) too. I didn’t try ROM Manager in CM9 but it should work. I always boot into CWM.

      • Matt

        Ah ok, so perform all backup and restores from recovery mode and not in android?

        • Yes, that’s what I always do.

    Hi Jayce

    I have a Samsung Galaxy SII and want to upgrade it to Android 4.0 but cant get the software.

    My Android version is 2.3.6

    Please let me know which one i can use and where I can find it.


      • Mike

        Thanks for the quick response.

        I had gone through the list an could not find any firmware that is related to the XXKL4 Kernel.

        Could i use CF-Root-SGS2_DX_THL_KL3-v5.0-CWM5 which is the closest I could see??


        • I am very sorry, Mike. I did not notice that your SGS2 is I9100G. So you can’t use I9100 firmware and CF-Root.
          Please use Samsung Kies to upgrade to ICS (if have for your region).

          • Mike

            Hi Jayce

    hi mate. have ota update ics kernel xxlq7, build xxlq7, base xxlq6. which cf-root should i install?
    is there a permanent root for sgs2?
    thanks and nice work.

    • Hi Knut, please consult others at XDA website as this is a new firmware. Don’t have exact CF-Root match yet.
      Yes, this is permanent root.

    if update ota, or any other way for that matter, root is gone. is there a way to permanenlyt root gs2?
    btw, i rooted with lq5; works fine.

    • Root access will surely gone after official firmware upgrade. Don’t use official firmware will do. Example, I use custom ROM which always have root access.

              yaaa i just tried factory reset also but the result is same 🙁

              but 3 days before when i had korean os everything was fine but when i used conversion of firmware from korean to english somthing has gone wrong 🙁

              now i have original korean cf root file and i wanna intall it so that it’ll become as it was earlier.
              k now my doubt is as i have installed siyahkernel,so before installing korean version should unroot it?

              • I am not aware that CF-Root supports Korean model. But you restore back to Korean firmware with Odin without unroot it.

                • viswas

                  k i’m gonna install korean os without unrooting ….
                  but before that i just wanna confirm from you that can i try android 2.3.4 Gingerbread on Samsung to my Galaxy S2 I9100 XXKG1 Firmware directly

                  does that harm my phone?

    Installed clockwork recovery on my phone using Odin. Now my phone won’t boot help. Galaxy s2

  • Juan Ay

    Just sharing my experience……..Had the same prob with the triangle thingy…had to use odin to flash stock kernal….now phone work like normal..(rooted and install custom rom again..:-) ….except the triangle warning sign is still there..but hp will boot like normal (slightly longer)…able to use CWM and so on..the only set back is that if I turn off my phone and turn on again phone will start but stuck at the triangle warning sign ..that it…the only way to start my phone is to enter clockworkmode and use restore…and i can use my hp again …..well i guess i cant turn off or let the batt completely depleted or ended up restoring again..

  • @viswas, factory reset in recovery first. Then install Gingerbread firmware with Odin.

    • viswas

      ok i’ll first factory reset….so can u send me a reliable download link of gingerbread firmware of any version….for my gt-I9100

        why is that there is no “apply update from INTERNAL STORAGE”?
        i cannot flash a zip file from internal SD.

        I am using SGS2 GT-I9100 4.1.2 jelly bean and i want to upgrade with a 4.2 my only problem is i can’t flash using android system storage coz it can’t read from internal SD.

        Need help bro.

    Is it possible to uninstall CF root in some moment? I plan to root phone so I can backup with CWM recovery and Titanium Backup Pro. Also, is installation of cwm use more RAM/battery than stock recovery?

    I’m on ICS 4.0.3.


    Kernel: 3.0.15-I9100XXLP7-CL340913

    Subversion: IML74K.XXLP7

    Is it possible to do CF root with cwm from stock recovery -> apply update from…

    • Yes, restore everything back to stock. CWM has nothing to do with RAM / battery.

      No, you need to use Odin to install CF-Root.

  • prabhat

    Sir, my friend has bought s2 in hongkong, updated to ICS.
    details :
    Baseband version: 19100DXLPB
    Kernel version 3.0.15-1056084 DPI@HP16#3 SMP PREEMPT Thu Aug 23 13:50:48 KST 2012
    Build Number IMM76D.DXLPF

    should i download CF “XW_OXI_LPF ” from this page ?
    If not, then which CF file shud i download ?


    • Hi prabhat, CF-Root is not updated anymore. You can try SiyahKernel.

      • prabhat

        hey jayce, with the above mentioned siyahKernel i will not be getting official JB updates. Isn’t it ?

        I just want to root s2 with “odin-cf” method so that i can remove unwanted apps and should receive jellybean official in future…dont need custom ROM 🙂

        guide please.

        • No, but you can always install official Jelly Bean firmware with Odin manually later.

          You can’t get OTA also if install different CF-Root on your kernel.

          • prabhat
