iPhone 4.0 -> 4.1 Preserve Baseband
I was using Tiny Umbrella to do a 4.1 upgrade while preserving a baseband (don't need an unlock but would like it for resale eventually). So i follow the directions from here:
Update iPhone 4 on iOS 4.1 Without Upgrading 1.59.00 Baseband to 2.10.4 [Guide] | Redmond Pie
The phone starts to restore. iTunes gets to 99% "Restoring Iphone Software" and iphone's status bar gets to about 75% and just hangs there. I left it for over 20 minutes and it does not make any progress.
I tried doing the restore from DFU mode w/ the same results.
