Restore to 1.1.2 OTB from 1.0.2
I have a week 46 phone (7U746), that I got off Ebay ...was told it was 1.1.2 unlocked, but reality hit and they sold me a phone that was jailbroken, but not SIM unlocked.
The phone is running 1.0.2 code, has Baseband 4.2.13G showing (thus I assume it was a 1.1.2OTB dye to week 46), but it has anySIM 1.0.2 on the phone and I have run it!!!!
Will running AnySIM 1.0.2 on the phone have damaged the baseband, such that I can't put it back to 1.1.2 and use a TurboSIM to use the phone?
Phone currently functioning on WIFI, but I need some pointers on how to restore it back to OTB condition, such that I can use the TurboSIM, and downgrade to 1.1.1 to jailbreak and bring back up to 1.1.2.
