Ok, this subject has probably been beaten to death, but I need some help please. I have s-off. H-boot .77 and baseband 2.15. I am technically still on 2.1 I just downloaded the leaked 2.1 radio and flashed a 2.2 rom. I need to get back to just stock 2.1 without bricking my phone so can download the real 2.2. Please help.
