Did Not Work

Ok, I had my SGII rooted with the ClockworkMod.Tar thru Odin3 and SuperoneClick. I also OC using Odin3 with galaxysii_OC_V1.tar thru Odin3 again and install setcpu..

I ran this unlock, but it never reboot, so I manually rebooted and check using the dail pad (from post here), and it says that I'm still lock.. I try it a second time and it did not work either..

Any Help will be appricated.. Also, my back button also does not work anymore. My Home button now acts as a back button.. anyone have this problem??:mad:

First make sure your superuser is working. As far as I know, there is no kernel for At&t GS2 that supports OC. Am I out dated?:rolleyes:
