“Help! Which file do I use?”
Go to Settings -> About phone -> Kernel Version. Note the string present there:

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

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 ?
best

I am trying to Root my Samsung Galaxy s2 and website says look for letters and numbers after Kernal Version numbers and all i have is this 2.6.35.7 What do I do?
my phone is nit rebooting after flashing kernel…
I can not start it or go to boot loader – I can only go to download mode – phone freezes with starting screen Samsung Galaxy SII and yellow triange with exclamation mark…
USING THIS METHOD ERASED MY PHONES IMEI #, BASICALLY ITS IDENTITY,
IT DID ROOT AND INSTALLED SUPERUSER , BUT WIPED MY WHOLE SERVICE
AS IF IT WAS ON AIRPLANE MODE!!! WHY WHY WHY
I think that if it failed that it is youre own risk and if it failed and now you cant start up your phone thn youre a big nub
hi i followed all your steps to the detail, except i had to find XWKDD somewhere else, but when i open up superoneclick and press root it freezes…why is that?
