How many variants of the Samsung Galaxy S2 are there? Wait, don’t start counting, that’s not the purpose here and will take up too much of your time. The answer, in short, is that are many variants of the Galaxy S2 with different hardware configurations (okay, not that many, but you get the picture). And usually, you’d have to look for a different tool or procedure to root or install ClockworkMod recovery on them.
But no longer will that be needed thanks to the Samsung Galaxy S II Toolkit by XDA Senior Member ajster1989, which guides you through rooting and installing ClockworkMod recovery on any Galaxy S2 device using a single toolkit. Not only that, it also guides your through flashing custom and stock ROMs using the toolkit, and sideloading APKs (install apps manually).
The Samsung Galaxy S II Toolkit (which is in beta stage at this time) can be downloaded from its official development page. Using it is as simple as connecting your phone to the computer then following on-screen instructions in the toolkit. So, give it a try, then let us know how it works for you, in the comments below.
