How to Root Samsung Galaxy S 2 i9100 – Tutorial

Pre Root Instructions:

  • Warranty will get void once you root Samsung Galaxy S2 GT I9100, though warranty can be claimed once you un root your device.
  • In an unlikely event you may lose all the data which is present in your Galaxy S2, so it’s recommended to create a backup of all the data like call log, messages, applications, music, videos and other data which is present in the phone, so that you can restore the same once the rooting process is completed.
  • Ensure that you have the installed the latest framework in your computer or also you can install the latest version of KIES which is dubbed as KIES 2 so as to ensure that all the required drivers are installed successfully.
  • It’s very important to maintain a minimum battery power of 50% so as to facilitate the smoother rooting process or else there is a high possibility that your device may end up turning completely off in the process of rooting.
  • Since the process of rooting will be taking place, all the APN settings with which you access the Internet will be wiped off completely, so ensure that you have noted all the required settings for accessing the internet so that you can configure them again back once the device gets rooted.
  • Don’t proceed to the rooting process if you have not updated your phone’s firmware to XWKDD as this may create un necessary force close errors in the phone which would require you to completely wipe the device which is bit of a tedious and unwanted process.
  • Last but not the least follow the below mentioned instructions carefully so as to save your phone from being turned into an expensive paper weight.

    I have the Samsung Galaxy SII since October, 2011. Yesterday, I was trying to open a web page, it froze and the phone got heated up near the camera area and got switched off by itself. Since then, I cant switch on my phone and whenever I try putting it on charge, it displays a low battery and yellow danger sign..Can I please be given advice on how the problem can be solved?

    Thanks for the very detailed guide, but I’m running in to an issue getting it rooted with SuperOneClick. I’ve updated the phone using your guide, which was successful, but I’m unable to get the phone to be rooted. When I run SuperOneClick it keeps hanging (stopping) on “Rooting Device…..- Step #6”. It completes steps 1-5, but it just freezes on 6. Phone is in Debugging mode, XWKDD has been installed exactly as the guide says, etc… I’ve lost everything on my phone (apps, contacts, etc..) after upgrading, so I’d really like to be able to root this thing after all the work of setting my phone back up. Thank you

    • Reply NeaL Pradeep August 8, 2011 at 2:28 pm

      yes you can root by following the article which is mentioned above

      • Reply Michael Corsi August 8, 2011 at 3:14 pm

        But, that is the problem. Following the guide it continues to just stop on “Rooting Device…..- Step #6″ in SuperOneClick. After which SuperOneClick crashes. I’ve now tried this 4 times with the same results. I’ve tried re-downloading SuperOneClick and the XWKDD_insecure.tar file, but still the same. My firewall and antivirus software is off, so I’m just really confused as to what is wrong.

        • Michael Corsi August 8, 2011 at 4:11 pm

          Ok, I got it to work finally. I used ODIN v1.83 this time instead of v1.85, not sure if that was the problem or not. Thanks for the fast response BTW! One question though, is their a way to remove the yellow caution triangle on reboot? I read through the responses, but couldn’t really find an answer.

        • NeaL Pradeep August 18, 2011 at 10:56 am

          no, its a bug which will not affect you!

        • NeaL Pradeep August 18, 2011 at 11:50 am

          close the kies and then try!

      • Reply Tralf August 15, 2011 at 9:22 am


        I am getting the exact same problem as Michael. Having successfully loaded XWKDD using Odin, SuperOneClick hangs at Step #6. In your reply to Michael you say that the phone can be rooted by following the manual (non-Newbie) procedure. I am a relative Newbie in the Android world, so I am having trouble following that manual procedure.

        When I do the “adb root” command, I get the response “adbd is already running as root” (which I guess is a good thing).

        You then say to do an “adb shell”, which responds with “#”, presumably waiting for me to enter the next shell command.

        You then say to manually push “Superuser.apk /su, Busybox”. This is where I get confused. Presumably that’s two separate commands “adb push Superuser.apk /su” and “adb push Busybox”. Is that correct?

        I am party confused because at that point I am at the “#” prompt inside the shell (which is presumably running on the phone). So shouldn’t I be doing a “pull” rather than a “push”?

        If I do either a “pull” or a “push” from inside the shell, I get “adb: not found”.

        If I try to do the “push” from outside the shell, I get “failed to copy ‘Superuser.apk’ to ‘/su’ : Read-only file system”

        Would it be possible for you to post a listing (or a screen shot) of the exact commands and responses involved in the manual method?

        All help gratefully appreciated.

        • NeaL Pradeep August 16, 2011 at 10:45 am

          since there will be more than 1000 commands, it will be difficult so kindly let us know which command you are exactly looking for?

        • Tralf August 17, 2011 at 1:25 am


          I was referring to your instructions prior to mentioning SuperOneClick:

          “As soon as the device is rebooted you will have to use the “adb root” command”…..through to…..”manually push the superuser.apk /su, Busybox”.

          As I read it, that is a manual procedure that is an alternative to using SuperOneClick. I was wondering if you could give a step-by-step guide to that manual procedure with the exact commands and what you would expect to see on screen in response to each command, so I could know if I am doing it properly and it’s working as expected (because SuperOneClick doesn’t work for me).


        • Tralf August 20, 2011 at 10:08 am

          OK – I found the solution to this. Instead of SuperOneClick, use the application here

        • Tralf August 20, 2011 at 12:36 pm

          The link I included in the post above got edited out. Basically, instead of using SuperOneClick, there is a specific program for rooting the Galaxy S2. You can find it by doing a Google search for “xda developers Galaxy S2 root”. The first result should be “S2 Root v1.2”. Follow all of Neal’s instructions, but use the program from that site instead of SuperOneClick.

          If you Google for “official i9100 firmwares” you will find another page on the XDA website that has all the stock versions.

          The procedure I followed in the end was:

          I already had Samsung Kies installed so the right USB drivers were present.
          Download Odin and the specific S2 rooting tool mentioned above.
          Put the phone into download mode (as described by Neal)
          Use Odin to load an insecure kernel
          Use the S2 rooting tool to assign permanent root privileges
          Installed Galaxy S2 SIM Unlock from the market and ran it (and noted down the number it gave me).
          Use Odin to re-install a stock kernel which I found via the official firmwares page (mentioned above).

          I have not yet put a “foreign” SIM into my phone to check that the unlocking code works, but I see no reason why it wouldn’t.

    I tried this on my new S2, the Odin part workd fine but the super one click just says ‘waiting for device’ and never comes back, phone seems to work ok but do get the yellow triangle and i also keep getting a ‘driving mode’ activation message.

    It appears the phone has not been successfully rooted as I cant get the unlock codes using unlock app as it says phone is not rooted.

    Since I did this my phone also doesnt appear to be recognised in Win 7 or Kies.

    I did this to unlock it but it appears I have probably just violated my new warranty with no reward 🙁

    I had the same problem as redshift
    I followed all the instructions exactly, but after flashing the kernel with Odin and XWKDD_insecure.tar, then the phone rebooted, it showed the yellow sign and then went on a loading loop (just keeps showing the samsung and carrier logo)
    It didn´t reboot back into its OS as it was supposed to.

    How do I fix this?

    I can turn it off and it shows the recharge icon (when recharging).

    I tried putting into download mode and that does not work, i get a screen saying:
    android system recovery (3e)
    with 4 options:
    reboot system now
    apply update from sd card
    wipe data/factory reset
    wipe cache partition

    Also has a warning
    # Manual Mode#

    e:falied to mount /preload (no such file or directory)
    e: install_application_for_customer: can´t mount/preload

      You dont need root to install non-market apps. You copy them to the sdcard, install a file manager (if you dont allready have one) and click the apk and install it.

      Rooting your phone does not make it faster.

    hi thanks for the tutorial on rooting, just got my tel. today, and have one small question..

    As soon as the device is rebooted you will have to use the “adb root” command

    what is the “adb root” command is that just adb root??? I mean do I put this into the tel. via the computer.?

    so i need a special program to run this command adb root.. can you please be more specific.. Sorry for the silly questions.. just dont want to brick my new tel.
    thanks for any help

    Samsung Galaxy S2 – After applying ‘XWKDD_insecure.tar’ using Odin and the the one click root (which all worked fine), I have the bios boot screen with a large yellow triangle, but the phone loads up just fine.

    Nothing was cleared from the phone… lost nothing.

    The only issue I’ve seen so far (thank fully) is the EA games no longer install, bit annoying but not the end of the world…

    Would be nice to remove that yellow triangle from the bios boot screen too… I’m guessing the phone has detected an unofficial recovery partition or something.

    Any ideas?

      The yellow triangle iis easily removed using an USB JIG (a mico-usb conector with some resistors inside). Just turn off the phone, plug the USB JIG and voilá!

      You can find them cheap on (I also sell them there, just look for “usb jig” on ebay).

    I had a problem when trying to root my phone. I followed all the instructions exactly, but after flashing the kernel with Odin and XWKDD_insecure.tar, when the phone rebooted, it showed a gray battery with the loading loop, and then started flashing the GS2 logo with a yellow exclamation sign underneath. After using Odin, is the phone suppose to reboot back into its OS?? Now my device is not being recognized by SuperOneClick, so the program just stalls at “Waiting for device…”. What do I do from here? If I turn my phone on, it just flashes the GS2 logo with the yellow exclamation sign, and I have to pull the battery out to turn it off. I can still start it in download mode though, but don’t seem to be able to get it to start in recovery mode. Please help.

      @redshft have you installed the firmware first?

      • Reply redshift May 4, 2011 at 10:28 am

        No, I didn’t update the firmware first 🙁 I was following the instructions on the xda-developers ( forum, and there was no mention of firmware. I tried to update the firmware afterwards, but I get an error about 95% of the way through the install. What can I do to wipe the device, and reset factory settings?

          Install Kies on your pc for drivers
