That’s all folks! You should have successfully rooted your Samsung Galaxy S2.

“Help! Which file do I use?”

Go to Settings -> About phone -> Kernel Version. Note the string present there:

2.6.35.7-I9100XXKG1-CL349526

What matters most (KG1) in this case, is in bold. Try to find the matching file under downloads:

CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4.zip

Just find the matching download and use it. ”

You can use CF-Root method by ChainFire or EasyRoot by DoomLord.

Just google it and it will send you to XDA Thread…

I will definately donate to your program,
I recently ordered an new Galaxy s2 . My questions first off. Do I need to activate the phone prior to rooting ? Also i downloaded the XWKDD file thats at the top of the page under “what you need” hope thats going to be ok . One more question , the main reason I do this root is to get free hotspot.
Can you recommend an app ?
