As I am well aware this topic might have already been discussed, I also apologize for posting this again.
I am not too experienced with rooting, flashing phones and so on. All I look for is to install supersu on a Galaxy S2 (gt-i9100) so that I can move a few apps in system.
Browsing for a few hours I have found a few one-click methods and also a lot of complicated ones. The thing is I do not need to flash the ROM or change the kernel, I just want supersu to work, that's it!
So far, the link I have found the closest to my requirement is the one on ibitimes link that says it's using the framawork app.
The guy who posted this says that it is taken from this site but I do not seem to find details on it.
I do not necessarily want to use it especially, I just look for a similar method. Please give me some suggestions if you could.
