iphone 3Gs with baseband 05.15.04
Good morning my friends,
I have run into 2 iPhone 3G running baseband that were accidentally upgraded.
I own a small repair shop, and I have a collection of IPSWs I compiled using Pwnage Tool.
I have a special IPSW that contains the iPad baseband, that I used many times for these bricked iPhones (3G) that worked perfectly for a long time.
But recently I have tried pushing the IPSW into the iPhones and it results in error 1015, apparently the process stopped on the moment the baseband was to be upgraded. The result is that I have to use iRecovery to put the iPhone back working, and the baseband is not upgraded.
I wonder what I am doing wrong, or, if Apple has somehow upgraded iTunes or the restore process, so to stop us from doing the baseband upgrade.
I will be very thankfull to read your comments, Thanks,
