Samsung Galaxy S2 received the long-awaited Android 4.1.2 official Jelly Bean firmware yesterday. The new update started rolling out for Spain and China. If you have downloaded and installed the firmware OTA or manually via Odin and now looking for a working rooting method, you have just at the right place now.
In the following rooting tutorial, we shall installed an insecure Kernel that would inject the Super User app into your phone and install the ClockworkMod Recovery mode. Having rooted your Galaxy S2 on Android 4.1.2, you will have the CWM Touch Recovery ver. 22.214.171.124. Siyah has packed all necessary tools in two formats- the one with .tar.md5 extension is meant to be flashed via Odin and the other with .zip extension can be installed by booting the phone into the stock recovery mode.
The procedure described here is considered risky and meant only for mature users who understand what it is all about. Neither the developer nor we at Droidviews will be responsible for any damage done to your Galaxy S2. The method has bee well tested and found working, but if do not follow the tutorial to the letter, you might make your phone unusable, and void its warranty too.
You can root your Galaxy S2 using any of the methods (preferably the first). We shall see both of them one by one.
When the phones boots up, it should be rooted with ClockworkMod Recovery installed on it. To verify the root, look for the SuperUser app on your phone. Alternatively, you can download the Root Checker app from the market and run it to make sure that the phoneis rooted properly.
If you want to only root your phone and do not need the ClockworkMod recovery for flashing custom ROMs or mods, use the method given below. The greatest advantage of this method is that it does not give the YELLOW TRIANGLE in return. Moreover the flash count is not increased and you will not void your phone’s warranty.
On booting up, your phone should be rooted. Download and install Root Checker app and run it to verify the root. Later, whenever you need to boot your Galaxy S2 into CWM Recovery mode, turn off the phone, press and hold the Volume Up+Home buttons together and then press and hold the Power key for a few seconds.
