Root And Unroot Samsung Galaxy S II With a Single Click [S2 Root]

Samsung Galaxy S II got rooted within hours of it’s release. Most of the folks opting to root their devices weren’t really comfortable doing it with CF Root kernel, as their was danger of device bricking etc. One click rooting solutions like GingerBreak weren’t applicable as S II mostly shipped with patched Android 2.3.3 Gingerbread on board. But when it is Android, there surely is a way and now you can easily root your Samsung Galaxy S II [S 2] with a single click using S2Root Application. The credit for developing this easiest rooting program for Galaxy S II goes to lyriquidperfection at XDA forums. The application comes integrated with Unroot option as well.

S2Root

Here is what the developer has to say about this release:

S2 Root – For Samsung Galaxy S II
Here is my One Click Root and UnRoot solution for Samsung Galaxy S II.
It has a very nice interface and offers options to reboot your device Normally, Into Download Mode or Into Recovery Mode after Rooting.

You can download Galaxy S2 Root Version 1.0 from here and then connect your phone to the computer, flash an insecure kernel and enable USB debugging to root your phone. The interface is pretty simple so there’s extremely less chance of getting lost. For more information regarding this rooting application, please consult the official XDA thread here. It is important to understand that rooting your phone voids warranty.

  6. This may sound like a stupid question. but have you been doing a full memory wipe when you flash the ROM? Of not that might help.

    • same as Adnan, but for me i downloaded the stock firmware used osin to flash it, but now every time i turn on the phone it never finishes ‘booting, and wont fully turn on. i previously flashed litening v5.o, and that installed fine, i have tried cognition, and viliian roms, but these never boot either, please help me, as i would like to install the stock firmware back on for my warranty.
      i can still put my fone in download mode, and it says samsung official firmware, but why wont it boot, and how come litening is the only room booting?? 😛 cheers

    • You need to make sure that the kernel is in a .tar format.
      That done, you should have the latest ODIN on your system and the Samsung drivers installed.
      Download the latest insecure kernel (and extract it) from: http://forum.xda-developers.com/showthread.php?t=1101671

      1. Put your phone in download mode (Hold the vol. down button along with the home button and press the power button.)
      2. Run ODIN and click on PDA. You would be prompted for a file, so select the insecure kernel (.tar).
      3. Connect the phone to the PC via USB and once it shows connected in ODIN (make sure re-partition is unchecked), hit the start button.

      That would be it, the kernel should be installed.
      Hope this helps.
