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.
@ZAKIR MUSTAFA
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?

@Shashwat Kauraw
Bro...why take risk ?...better back up all files
Thanks!
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!!!
Will this method of rooting support CPU control, or apps like SetCPU app??? To minimize battery drain....
@abhayprakashtiwari
