How to Root Galaxy S2 i9100! [ICS][Android 4.0+]

For those of you who want to root your Galaxy S2 GT-i9100 on ICS (Ice Cream Sandwich Android 4.0+), here’s how to do it by flashing a new kernel.

Step 1. First, put your Galaxy S2 into download mode by holding down Volume Down, Center, and Power button together for about 10 seconds.

Step 2. When you see the warning screen, hit Volume Up button to enter download mode.

Step 3. Connect a micro-USB cable from your Galaxy S2 to your computer.

Step 4. Download ODIN program and CF Kernel.  Then unzip both files. (Don’t have unzipping program? Download and install 7Zip.)

Download ODIN

Download CF Kernel

Step 5. Run the ODIN program.  You should see a yellow highlighted rectangle box with a number.  If you don’t, you need to install Samsung Kies.  Download Samsung Kies and install.  After installing, un-plug your phone then plug it back in, you should now see it.

Step 6. Hit “PDA” and choose the “CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar” file you unzipped earlier.

Step 7. Hit “Start” and the kernel will start flashing to your phone.

Step 8. Your phone will reboot when it’s done.

Step 9. Once you reboot, check that you have the SuperSU app.  If you do, you are rooted.  Congrats!

  3. Mike says:

    i think this is better than LPQ stock. BTW, email works fine here unlike the stock.

  4. Darryl says:

    I tried this after installing ICS resurrection PRO Edition v1.0 and got a black screen.

    I used the stock ICS and odin to get my phone back working.

    I then flashed this kernal and then ICS resurrection PRO Edition v1.0 which seems to have worked!

    • maxali says:

  5. Chand says:

  7. Java1784 says:

    I am at foreign lands and tried it as the video shows, I showed the yellow triangle and then all I am getting is a black screen. Any suggestions? Thanks!

  8. Andrew says:

    I tried this on my girlfriend’s new phone but was in a hurry (deadline to meet) and forgot to enable usb debugging. Kernel flashed okay according to Odin but now I just get a black screen. Tried flashing official ICS Kernel to see if that fixed it, same thing. Can’t find the official 2.3 kernels for the phone anywhere. She’s going to kill me.

  9. Chris says:

    This was the rom that got me into flashing! I got so pissed of at samsung for having ‘swipe to unlock’ locked on the startscreen, and telling me there was no way around it!?! So I went from here to ressurection remix pro 1.0

    Big thanks!

    same problem as bill please help

  12. Dave says:

    Also hit same issue as above. Joys of rushing things. A quick read could have avoided. Luckily you can boot in to CWM and flash what ever ROM you like.
    But does any one know if/how to recover contacts from the ROM that is now stuck in not booting?

  13. Mike says:

  14. mike says:

    can this one support my SGS 2 I1900 G version ?

  15. Xavier says:

    CF Root is awful any chance of normal root method as some apps do not like CF installed. ie get errors as sd card is not mounted. Proper Superuser (in green icon) didn’t give me this error.

    Thanks Zee

  20. Bünyamin says:

    I have a problem, I rooted my phone, and backed-up my android 2.3.5, now I have put an ICS rom, but I want to unroot my phone, but when I wanted to restore my 2.3.5 back-up it says that there is no file!
    Can someone help me?

  21. Dan says:

    Hey. Great site. Great vids. Question to this rooting. Under my phones settings i read that the kernel running is:
    3.0.15-I9100XXLPQ-CL223505 se.infra@SEP-94 #3

    In the instruction the zip-file is called:

    What im trying to say is, its different. Works with XXLPQ/stock-ics as well? Aiming to be able to backup my phone and slowly start flashing.

    • Dan says:

      Aha. My fault of being nonchalant. Hehe. Now read “XEO_LPQ”. But then another question. With this rooting, am i then still able to download Samsungs updates via KIES? Presuming of course that i only root (and not start flash).

  22. Amanjeet Singh says:

    i did till the part where the .tar file is flashed (thats the term i guess)…and then after the screen with the yellow triangle my screen goes black….kindly help me asap! …

  23. NeXt says:

  34. Diogo says:

    My kernel is I9100BOLPD. Can I install another kernel version or should I look for this exact one?
    Sorry for being such a noob.

    • Ybother says:

      It depends on the ROM you are using, some kernels require a certain version. Thoravukk on XDA work with many. Read the kernel and or ROM threads on XDA. Ask if necessary to find the best combinations.

  35. Ybother says:

    An easier way of rooting SGS2 on ICS is by holding Vol up, Menu & Power buttons and flash Busybox installer then CWM through the update from zip from your SD card. Odin not needed.

  36. ram says:

    hi i installed as video instructed but when came to clicking super su on phone it says installation failed please help

  37. ram says:

    also wifi functionality doesnt work it doesnt pick up my wifi now…any advice please

  38. elqqqqqqqq says:

    I can run ODIN on Linux O_o .ok i just dowloaded WineHQ so i could run odin on linux. so CF root also works on linux.

  39. Maarten says:

    Does not work. SG2 won’t start up after I installed it.

    I have ICS installed (I9100XXLPH):

    Do you know what I have to do to root the phone ?

    Thanks in advance for all the good work.

  40. Christian says:

    All you faggots which got a blackscreen after doing this, PLEASE first check if you already have ICS installed. If not do that first (you can install an official version without root acces) and THEN and only then use this tutorial.

  41. jalal says:

  42. Oscar Gatta says:

    Worked perfectly on 4.03. Very easy to follow, only took 10 minutes. Thanks.

    • Oscar Gatta says:

      Actually, my SD card doesn’t work any more? Wont let me install apps to it, the apps that were there don’t work, and I can’t access my music. Any ideas how to get this working?

      • admin says:

        Hmmm, not sure on App2SD, will look into this but your music should be all there.

      • admin says:

        Your SD Card is under /EMMC

        • Dean says:

          I have the same issue, root went ok, but the SD card stopped working properly, i can still access pics and music but moving apps to it doesn’t work, just says ‘couldn’t move app’, and some apps wont even download from the market unless i unmount it.

          Also all apps that were previously on the sd card don’t work.

  43. Sreekanth Chaladi says:

    It worked like a charm for me on my Latest ICS 4.0.3 BVLP build on Galaxy SII.

    Now building app data and re-configuring apk’s that suits my style and nature.

    Thanks for allowing me to root my ICS early.

    Ice Cream For you Mod + Dev


  44. mats says:

    Pls update choice of kernel to CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5.tar as V5.3 makes some apps refuse to be installed. e.g. RealVNC ans Svampguiden……

  45. JaumeI says:

    Everything went smooth, but now the apps I have in my SD won’t work, and if I download any app that installs directly to the SD card, i get an error. How can I fix this?

    • Ybother says:

      Your SD card is probably /emmc, a different location than previously. You could try installing an older ROM. Might need to reinstall the apps.

  46. Sumit says:

    I had Updated unrooted galaxy s2 to android 4.0.3 officialy via kies. Now I used this method to root. Worked nicely but I cant move my apps to memory card via apps 2 sd

    hey my phone not start…stuck on samsung galaxy s2…damnnn

    • Ybother says:

      If you can boot into download mode, go & search xda for either a stock ROM or Resurrection Remix if you have root. If not follow my previous post. Resurrection has a brilliant community to help you if you have problems.

    • admin says:

      do you have i9100?

  49. Lem.Cruz says:

    thanks man. easy as pie.

  50. Harshit Kukreja says:

    Help pleassseeee.. i tried to root via your instructions , got stuck at the step where the phone is suppose to reboot . Get stuck on the screen with the symbol of samsung galaxy s2 and a yellow triangle with an exclamation mark. Odin says that pass and then disconnected. Help plsssssssssss

    • Max says:

      you do have i9100 on ics?

      • Harshit Kukreja says:

        no.. i have gingerbread.. 2.3 … and i think i forgot to put the phone into usb debbuging mode..what should i do??

    • Ybother says:

      If you have a SGS2, your question has already been answered earlier in the thread. Have a read or visit xda.

    • Antonio says:

      Use Odin v1.7, flash CF as in this tutorial, and see if it boots. If it goes after the yellow triangle but doesn’t boot completely, flash a stock firmware with Odin 1.7 to get it back alive. 🙂

  51. Vijay Roy says:

    I am running {ICS version 4.0.3}
    Kernel Version {3.0.15-I900ZWLP7-CL340913dpi@DELL134 #3}

    Please tell me if i also can root my phone using the above method.

    I am worried if this will not work for my kernel version.

    Thanks in advance.

  52. JM says:

    Really straight forward, took me two minutes! Thanks for the tutorial.
    One thing I wasn’t sure about and read about on other tutorials was whether to check ‘USB Debugging mode’ before starting because your tutorial doesn’t say to do that. I did it just in case and it worked fine so *thumbs up* 🙂
    For those interested, original kernel was – 3.0.15-I9100XWLP7, stock ICS version 4.0.3

  53. mats says:

    PLS update guide with CF-Root-SGS2_XX_XEO_LPQ-v5.4-CWM5.tar
    v5.3 as in guide do not allow several apps to be installed.

    Otherwise the guide is great

  54. nick says:

    hey mate, i am having a galaxy s2 i upgraded the firmware from GB 2.3.3 to official ICS 4.0.3 using kies,

    can you help me in rooting it ???

    following are the details

    MODEL NO -GT-I9100
    baseband version-I9100DDLPA
    kernel version-3.0.15-I9100XWLP7-CL340913 dpi@DELL134 #3

    many thanks in advance

  55. David says:

    Guide works fine, but there is one annoying thing after it’s done.

    My phone keeps on askim me to do a system update (probably due to kernel update) and I cannot get rid of the message. At most i can delay it for 1 day. Even if i go to settings and turn of system updates, the message is still there. How can I get rid of it? If I do update the phone that way, the root is gone and I have to re-root it again and I’m back with the same message again.

  56. Matt says:

    Okay, I’m using a Galaxy S II GT-I9100T running ICS 4.0.3, updated legitimately from whatever i bought it with. Will this work for me? Seeing all these people who have fucked it up kinda makes me cautious.

    • Matt says:

      Also, do you need any other information?

      • Ybother says:

        There’s always a risk. I have flashed a lot of ROM’s. A few haven’t booted AFTER flashing& I have restored my backup. Only twice have I needed a PC, rooting from Gingerbread (no alternative and once a soft brick (bad download). I don’t use Odin if I can help it (more to go wrong). People who have messed up have probably not followed instructions.

        Best to follow the instructions on XDA (listed above). Backup with cwm or clockwork. Then flash a good ROM like Resurrection Remix after downloading the 3 (total) files onto your SGS2.

        Good luck.

      • Ybother says:

        BTW the only difference between yours & the international version is the modem. Everything should work, any problems flash another modem, search xda for them.

  57. Jeffrey says:

    Works good m8, ty!
    Only got 1 problem, i cant move apps to sd-card.
    sd-card itself works, i can open the music on it, but why can’t i move apps to the sd-card?

    • Jeffrey says:

      Allready solved. Reflashed the stock kernel, got rid of the yellow triangle and sd-card works again.

      • camboja says:

        Where can I get this stock Kernel and how to re-write it back again? With Odin?
        Some apps just won’t install on my device!

  58. one111 says:

    and if you don’t see the SUPER USER icon ?? bricked??

    I’ve done all the steps as stated above , but i’ve got one question. After rooting and starting up , some of my apps doesn’t appear or start up. What’s wrong ?

  60. erall says:

    Need request urgentlly,

    Hi, I have a little problem ther. I allready installed KIES and the computer recognize my SGSII ICS but Odin didnt recognize. So i uninstalled my usb ports chekd ones more again but windows recognized my mobilephone ad installed driver but no hope from Odin app. The problem is I allready put my SGSII on download mode. What can I do to solve this prob. Thnk u for your attencion. Sorry for my English.

  61. anothernoob says:

    hi. i have a GT-I9100 on android 4.0.3 (unrooted and updated to ics through kies)
    kernel: 3.0.15-I9100DXLP7-CL233393dpi@DELL166#3

    my questions are:
    1) can i use the above method and the above kernel to root my phone?
    2) are there compatibility issues between kernels? for example my DXLP7 can only be flashed with a rooted version of DXLP7? or i can use any other kernel?
    3) how can i identify which kernel will work on my phone?

    • Max says:

      The CF Kernel is compatible across all i9100 on ICS regardless of your kernel/software version. You can also use any other ICS kernel to get root.

      • anothernoob says:

        Ok thanks!

        I’m still a bit apprehensive/scared. Any idea why those guys above bricked their phones?
        What are the common causes of bricking an s2 during rooting? ( I just wanted to avoid their fate)

        Should I enable usb debugging?
        Any other settings/steps i should do before doing the above stated steps?

        sorry for all the noob questions 🙂

        Great work and more power!

        • Max says:

          They may have “soft bricked” which isn’t brick and recoverable. Just follow the directions one at a time and it should be fine.

  62. anothernoob says:

    Ok thank you again!

    Hey, tried the method using heimdall 1.3.2

    SALAXY S2 GT-I9100
    ANDROID 4.0.3
    Kernel Version 3.0.15-I9100XXLPQ-CL223505

    I used the CF Root provided and all seemed to work fine. It rebooted with the ‘exclamation’ mark. Titanium could not gain root access. Also I could not install any apps from the Google Play ‘Couldn’t install on USB storage or SD card”.

    I am stuck and not sure where to go.

  67. Paul says:

    Does this erase the phone or reset it?
    ie will the root process leave the current apps and data

  68. Paul says:

    Where is the latest CF root, which fixes the SD card problem ? ie CF root 5.4 or 5.5?

  69. Eddy says:

    Hey all,

    I’ve got a huge problem. Many other people have got this too.
    I followed these steps and my phone rooted succesfully. Then
    I was trying to install a custom ROM, a Galaxy S2 Recovery from or something.
    After this my phone won’t turn un. When I hold the power button, the normal boot up text appears and a yellow triangle. I tried to clear the hardware via ClockWorkMod, but nothing helps. Everytime I turn my phone on the text and the yellow triangle appear and nothing happens.

    Please help me out,


    • Dave says:

  70. huron says:

    Please help me!
    After following the above instructions the samsung logo appears with the yellow triangle followed by a black screen.
    This is my first Android phone (GT-I9100) and first attempt at rooting. I basically know nothing.
    Am in Jamaica with Digicel as provider.

    Would greatly appreciate some step by step assistance .
    Is my phone a goner?

  71. Justin says:

    Hey man, very nice website. I’ve watched almost every single rom video of yours about the s2. I have a question though. I’m debating if I should install an AOKP wrong on my GS2 right now cause i like how fast it is and the stock google experience. I’m just wondering cause I have an i9100T version of the GS2. would the same rooting method work for it? (BTW this i9100T version that I have is from Telecom New Zealand) I think it’s the same as the international version. only to differentiate it with the Telecom variant hence the T. but I’m not sure. Your answer would really be appreciated.

  72. Iraj says:

    Hi all.
    I install ICS on my GS2 but when I press the power button the phone turned off and also face detection not work. Im sure that the framware is ok becuse I use it on another GS2 and its work well. Please some one help me.

  73. Robert G says:

    oh my god. why… why did i try this? first time and i fuck everything up. fuck you friday the thirteenth.

    damage done : usb will detect phone but not any storage at all. reinstalled drivers, tried different ports, tried debugging mode, nothing. Odin sees the phone but can’t write to it.
    wifi won’t turn on, period.
    can’t access any of the folders that CWM can see, so can’t really change the firmware or anything i think…
    going into settings -> storage results in settings crashing immediately.
    download mode doesn’t seem to work, since odin can’t communicate with it… i don’t know what to do… i’m gonna cry, wtf…

    • Robert G says:

      false alarm. was having all those problems, but i tried running the installer again, selected the options manually for a different kernel and stuff , and it worked, now wifi works, usb mode works, not sure about the others, but upgrading to 2.6.0 right away whilst i’ve got the momentum.

  74. Dave Carr says:

    Okay I’ve now successfully Rooted my Galaxy S II Android ver 4.0.3 ICS using the instructions above now what is open for me to do with my Rooted device.

    CWM & SuperSU were installed as part of the Rooting process.

    With my cell the way it is now would I be able to install custom ROM’s using CWM & when they are installed will it cause the Yellow Triangle to re-appear once again?

    Also if another official version of Android comes out like 4.0.4 ICS or 4.1.x Jellybean & is upgraded either OTA or via Kies will I have to re-root my cell again?

  75. Nikolai says:

    Did everything according to instruction: everything works fine except camera. I mean, I can take pictures and videos but the screen is totally black during picture-taking process. Any ideas how it can be fixed ?

  76. Andres Villalba says:

    I had the same problem of most with the yellow triangle and then black screen. Here is the solution. You have to be sure which version of the CF-root you are downloading. I download the one in this tutorial and it didnt work because I had a differnt kernel version. I had to search in google for the CF-root for my version, in this case: CF-Root-SGS2_XX_OXA_LPJ-v5.3-CWM5 …i have XXPLJ with ICS 4.03

  77. Marcus says:


    • Max says:

      Which i9100 do you have? model number? Make sure you don’t have i9100G.

      • Marcus says:

        i dont understand that but from what i can read at the back is
        model GT-I9100
        ssn -i9100gsmh
        does that help i cant see others because my phone is completely off and black on the screen please help and thanks for the early reply.

    Hey! I am from Mexico and I had actually the original ICS, so I did root my cell phone and it worked. I wanted to erase the mobil company provider softwares but I wasn’t really able, don’t know why. The fact is, if I ever want to sell the phone I will have to unroot it, and I tryed your method but it didn’t worked (my model is i9100), can you tell me how can I unroot it (what do I need to look for)? since I actually never backed up the original software I should do that right away and then root/unroot, change rom etc…

    • Max says:

      Sorry YouTube removed my videos and my tutorial is gone, I am going to try to see if I have it but in the meanwhile you can try XDA Forums for unrooting instructions.

  79. Marcus says:

    @ Max Hi am still waiting or your feed back please help

    • Max says:

      does your phone turn on at all? do you see anything?

      • Marcus says:

        @ Max it’s off completely and i can not see anything but when i put it in the pocket for some time it heats and i believe it still has life but how to put it back on i don not know

        • Max says:

          It might be a broken LCD, try puttinng some pressure on different parts of the LCD after pushing the power to turn on the screen see if touch works, do the unlock swipe. If it does, it’s a bad LCD.

          • Marcus says:

            Hi Max i believe the Lcd is fine this started after the the yellow triangle when i was trying to flash it. so i still think the LCD is safe do you think it could be some thing to with the Bootlom?

            • Max says:

              So this happened while rooting? Do uou have ics?

              • Marcus says:

                yes it happened while rooting but i do not have, probably i should be asking what ics you are talking about is it a software oh hardware stuff?

                • Max says:

                  ICS is Ice Cream Sandwich and GB is Gingerbread.

                  If you have Android 4.0+ it’s ICS, 2.3 it’s GB.

                  • Marcus says:

                    okay i have that but can it start my Phone since it’s off completely can it come one with this particular software? thanks Man i am relying on you to have my phone back

    I use to have ICS ROM and one day my friend crash my phone, so I try your method to save my phone. The problem is I connect my phone and finish using odin it does show PASS!!! and I was waiting to reboot. But my phone can only see the “samsung galaxy s2” with a yellow triangle with “!” and then black screen all the time, cant boot my phone. What should I do?

  83. Alex M. says:

    Hello guys. I have rooted my device one month ago, and today i decided to unroot it. So iused Odin and installed stock ics rom. The thing is i can’t root it back. When i connect my device through ODIN, and use PDA CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar, ODIN say’s :
    Odin v.3 engine (ID:7)..
    File analysis..
    Can’t open the serial(COM) port.
    All threads completed. (succeed 0 / failed 1)

    I’ve tried different ways to make it work, like run ODIN in compatibility WIN XP SP 3 in administrator mode. Changed the usb ports, and nothing.
    I want to root the device again to install a custom rom, beacouse i like when i can change anything to my phone.

  85. Thommo says:

    This way is so stupid and a load of utter nonsense
    You don’t even need to flash kernals connect to Pc run this run that – odin mode nonsense

    Download this file from my storage
    copy it to the root of your phone memory NOT SD Card memory
    Switch off your phone press and hold Volume up – Home and then press power – When the Galaxy S2 screen appears release all – On the screen if you get into it – It will say update from external storage – Using volume buttons highlight this option and press power button – On the next screen look for Superuser-3.1.3-arm-signed using volume button highlight this and press power button to install – If it says complete with no red txt saying fail then congrats your rooted simply reboot

    followed the procedure stated on this page as of 19 August 2012. ran into the problem where apps installed on sd card don’t work. did some researching and found out the CF root 5.3 had problems mounting the sd card. there is a newer version 5.5 from the developer. use that and you’ll be fine. here’s his xda link:

      AND don’t just rely on the CF root posted here. go on the xda link i posted and try to match your version…. for me it was LPG, which happens to have a LPG v5.5

  106. steve says:

    OMG I F**cked UP!!!

    I have a SGS2 i9100 and by being a bit of a twat I flashed the wrong root
    I accidently installed the i777 root
    So then I did the correct i9100 root – CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5
    But when I went to super user I got “THERE IS NO SU BINARY INSTALLED. this is a problem”
    So I installed Super SU from Play store
    Now when I go Super SU it says
    “The SU Binary needs to be updated”
    installation failed!

    Also when I go into CWM I get “this version of CWM Manager should be used with CF_ROOT v5.0 or newer. It appears you are running a different kernel. Various features have been disabled”

    Thankfully my phone is still working normally, but it obviously isnt rooted properly.

    What should I do now, or am I screwed? Thanks

    • steve says:

      Not sure if this is important or not, but when the phone turns on it says gt-i9100 but in Odin it says Epic 4G

    • Max says:

      You should be fine, just re-install CF Root for fix.

      • steve says:

        Ive tried that and it seems to be in a weird half rooted state, I get the yellow triangle, I can install Adfree but it doesn’t work, and when I verify Root access with root checker it says I do not have proper root access.

        I’m not quite sure what I’ve managed to do……..

    • Michael says:

      I’m very new to the whole rooting and installing custom software to my SGS2. And this is the second tutorial I am following from this site and I’m very happy i stumbled across this great library of information.
      Thumbs up man keep up the good work and, I just rooted my SGS2 with ICS 4.0.4. Now, I followed all the directions downloaded everything and it all went as described. I am going to go play around with it and see if I have same problems as the other users. But for now it all seems to be working normally and I got my Super SU icon and CWM icons.

      Note, I did stumble across some scenarios that were not mentioned, that i will mention just to add some information.

      When I opened my Kies just to make sure it was still working it asked to update and it did take like 3 minutes to update it to the most recent version. After that it downloaded some additional files and it was done.

      When The device was rooted and all the process was complete, the phone restarted and the computer said recognized samsung galaxy device and that it would install drivers which it said it failed to install drivers. I will restart pc and try to plug it again see if that works. I will follow up with this when i get to it. Other than that, it all worked, thanks. And happy holidays everyone.

    Finally my i9100G is back alived! I just flash with default firmware and all went smoothlly 😉
    Btw, if you can’t turn your phone in download mode, without USB jig , still can make it happen.
    Just take your battery out, hold the 3 keys and put back in your battery 😉

  129. Adrianmol says:

    I used this site to root my Galaxy S2 and I had no problems. My Samsung Galaxy S2 had been rooted for a year and was running well. I upgraded to ICS via Kies on 10 Nov 2012. The upgrade took away my Root access and returned all the settings to stock Vodafone/Samsung so had re-install all my icons. My S2 was running well but battery life was awful due to all the bloatware from Samsung, Google and Vodafone. With Juice Defender I had been getting nearly 2 days of light use, after ICS was installed this went down to 8 hours max which is hopeless. On start-up I had Social Hub error messages and whenever I went into the App Store Google kept trying to update “Google” apps that I didn’t want and never used.
    So I found this web site and rooted my phone again which enabled me to remove 16 Bloatware Apps plus about a dozen free trial apps which had appeared from nowhere Success I can now make my battery last well beyond 24 hours.
    The only downside is I have about 12 Apps which no loner work in ICS, including most of my 3D Flying games.

    I rooted my samsung galaxy gt-i9100 exactly like you did in your video, but now I am having a problem: when I leave my phone with the screen shut off for 20 minutes or so (sometimes more sometimes less) the phone shuts down, and it doesnt turn on unless I do a battery pull or I push the ON button for about 20 seconds. After I rooted the phone I used an app called “Battery Calibration” to see if it helped thinking it could have been the battery but it did not work. PLEASE HELP ME! Thank you

  154. URSO says:

    Hi I got the GT-I9100 S2 and followed these steps to root my phone on ICS. This process worked and I gained SuperUser access but after trying to enable my Bluetooth, I noticed that is no longer working. Tries to enables but fails. Also when using the native camera app, the viewfinder no longer displays the image the camera is seeing. Its just a black screen.

    Anyone know how to fix this?

  155. BlackDon says:

    Hi URSO & all the other people who gain this problem,

    For a few weeks back, I had that same problem.
    I’ve tried everything but nothing helped.
    At one time it was this far, I accidentally replaced my files by other files because of my root access.
    Of course this wasnt what I wanted.. After it replaced al this files. I triet to unroot it, and I got all of these errors.
    And I tought about the thing I maybe bring this phone back to the restore center who would delete my rom and install the original Samsung i9100 rom back, so this problems with bluetooth the black camera screen and also I had a problem with streaming of video’s.
    But I could not send my phone there if my download counter of odin was still counting up and not null.
    So I decided to root my phone once again. After I rooted my phone again, I looked at my camera, bluetooth and video’s and they where WORKING!!
    But I think the risk is to big because of the instable root rom so I installed triangle away. Inside this app triangle away is an option to set this odin counter to zero.
    But if you do this you will have to take a major risk because if you do you got this change to softbrick you’re phone… but I took the risk and my odin counter on my phone hitted zero.
    Right now I unrooted it again and I watched after this unroot if my counter got up.. but instead of getting up it stayed zero. So i was pretty happy, because my bluetooth, camera and my video’s were still working.

    Ater all this.. I installed some random app’s so it would look like this phone was in normal use.
    I called to the center and called my problem that my phone wouldn’t connect with Samsung kies.
    I told them I got an error what tolds me my phone wasn’t compatible with Samsung kies.
    They told me a big crappy story about it could be a software problem and blablablablabla
    So I asked them if they could install new software on my phone and they said yes.
    So I went to the store and I told them I had called, they knew my problem already and 2 hours later I got my phone back with the original software.

    I know this story above is pretty much, and some of you think its crap.. But this is how it go’s with my phone.
    By the way, I’m sorry about my bad english.

    I hope you guys have something to this story.
    If you don’t understand anything please let me know.
    For all the guy and girls who search fast trough this topic.
    There isn’t a propper solution jet for this problem with the black camera, bluetooth or black video’s.
    Its an fault in this ROM and someone needs to fix this.
    But beside the faults in this ROM its a pretty good one.

    Cya all later =)

    Hi Max,

    Can I used a JB custom ROM after I root my ICS kernal? I am currently on 4.0.4 DXLPF and I am thinking of using the new 4.2.2 PacMan JB ROM. Do I need to flash Siyah kernel to be able to use the JB ROM?

    Hi Max,
    currently my almost 2 years galaxy s2 are having problem with its wifi connection (wifi icon stay dim green & cannot detect wifi) which I am sure a lot of galaxy s2 owner out there are also having the same issue.

    I already try almost all the tricks that I can find to solve it but so far no success.

    Now, I want to try to root it by following your guide. May I know whether my wifi connection problem will somehow hinder me to root my phone. Currently on 4.0.3 official JB. Any possibility of bricking? Thanks.

  176. abdellaj says:

    thanks it works on my s2 i9100

  177. Jinner says:

    Easy to follow instructions and worked well, although:
    1. Any apps on my external sd aren’t working – it looks like the card is unmounted (it isn’t, I can still access stuff on it via My Folder). Is there an easy fix for this?
    2. This “CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar” kernel is enough to go on to other steps for changing ROMs now?
    [Sorry – new to all this]

    Hi Max, i wroteted u here because i am not sure if we can contact you via mail even though I’m a subscriber. So i finally decided to flash custom kernel and i encountered problems. I am on a stock 4.1.2 but i have rooted my phone, i have stock recovery (didn’t need CWM because i just wanted to install viper and titanium) and i tried flashing DorimanX kernel 8.43 with odin 1.85 and when phone rebooted after DorimanX boot animation my screen turns black, i waited for a while a nothing happened. So i tried to find solution on xda and someone mentioned to wipe cache,wipe dalvik cache and fix permissions, but then i got boot loop. Then i tried GS2KernelWipeV2.09 script from xda (i maybe shoud mention that i can enter CWM and go to download mode) i tried flashig again and still won’t pass DorimanX animation. I tried with 8.42 version and still the same problem. Then i tried Siyah-s2-v6.0b5 kernel, won’t pass Siyah logo, then PhilZ-cwm6-XWLSD-OXX-4.93.6 and still won’t pass screen with triangle. After that i tried your way (because it had jeboo kernel and people on xda say that DorimanX and Siyah are better), followed all the way but it won’t pass screen with triangle (like the pic below step 8). Every time i flashed odin said pass, phone reboots and nothing. I see a lot off people ask if the usb debbuging should be turned on? Is that my problem? Finally I flashed stock rom and everything is working now but i would like to flash a custom rom in the future so if u could help me I would be very grateful. Thanks in advance!
    P.S. sorry for my spelling english is not my native language
