Hi, So I got iPhone 3g on version 2.2 locked on T-Mobile. I've made a custom ipsw 4.2.1 with pawnage tool and restored iPhone. Then I wanted to unlock it BUT I have baseband 2.28.00 that can't be unlocked (I think) on 4.2.1 so I want to downgrade iPhone to 4.0 and then again restore it with custom ipsw on 4.2.1. Now my iPhone is in DFU mode and it can't be downgraded to 4.0, WTF? I am getting errors like: The iPhone "iPhone" could not be restored. This device isn't eligible for the requested build. and Click for large view - Uploaded with Skitch What should I do??? Please HELP ME!
