Can't go to 1.1.1 from 1.0.2, please help!
I keep getting an "Unknown Error (1)" or "Unknown Error (4)" when I try to upgrade to 1.1.1 from a virginized iPhone running 1.0.2. I'm on Windows.
The iPhone was previously unlocked with AnySIM 1.0.2, virginized, upgraded to 1.1.1 and unlocked with anySIM 1.1. Where it worked fine until I tried to use the oktoprep method to upgrade to 1.1.2, after it upgraded AppSnap said oktoprep wasn't installed properly and I was stuck. I couldn't go back to 1.1.1 in recovery for some reason, so I went down to 1.0.2, virginized the baseband again, and confirmed it that the modem version is now proper. Now I can't upgrade to 1.1.1 again, it gives me the above errors when I try do so.
How can I fix this? I really would appreciate your help with this.
Figured it out, the old iTunesMobileDevice.dll was the problem, 7.5 requires its own dll to restore firmware, it won't allow you to use an old dll (which I had put in there to use iBrickr).
