Help with Rooting S2

Hi All,

As an ex iPhone owner, I am new to Android. I want to root it so I can put on my own ROM.

I have found a straightforward method and already stuckon stage 1. TYPICAL.

I need to find an insecure kernel, but I cant find one. My existing on my v4.0.4 android S2 is

Kernel Version
3.0.15-I9100PBVLPC-CL1020445
dpi@DELL153 #3

Anyone know how I find one for this?

Thanks
