Like the previous root methods i was posted here .. this method also simple and secure as it is not using any root tools or insecure kernel.

The method is simple .. just install the provided zip package from stock recovery. The zip package is created by XDA senior member PhilZ.(thanks for making this).Please check the firmware details..... if your phone have the same firmware below then you can install this zip in your phone..otherwise don't try it.

Must Note:
- This root package is only for International Galaxy S2 I9100 Android 4.1.2 XWLS8.
- Backup Impotent Data.
- Battery Charge Must be 60% or above.

* Rooting may void warranty or it may brick your phone ..we are not responsible for anything at your risk.

Root Galaxy S2 Official Jelly Bean 4.1.2 XWLS8

1. Download 4.1.2 XWLS8 Root zip package from here (v4.0 B22)
2. Copy the downloaded zip package to external SD card.
3. Switch off your phone and wait till vibrate.
4. Boot in to stock recovery ( Volume up + Home + Power )

    I have rooted my i9100 with cwm 4.0.15 that is more buggy. I want to root it with cwm6 as u posted. How can I do that any idea.

    29 January 2013 at 05:51

    CWM is not root its a custom recovery ... if you have bug with CWM then you can install CWM6 or any version....which Android version currently you have in your S2?

    29 January 2013 at 07:32

    Currently my device is on JB 4.1.2 xwls8 which u have posted earlier thanks for that..

    I had spent the past 4 days searching for ways to root my S2 after upgrading it to jellybean without the trouble of using odin. And then this lifesaver happened. Now with the power of root I can again hack the gold in dead trigger and resume with my zombie massacre. Yeeehaaaaa!!!
