"iPhone could not be restored because the firmware file is not compatible"
Hi Everyone,,,hopefully someone can help me as my 3GS iPhone is unsuable...
First of all I managed to get locked out of it...dont ask me how...so I need to restore, but I would like to be able to JB it again....currently it is jb-ed and on 3.0(7a341), bb 04.26.08 and 06.04 bootloader. I wanna go to 3.1.2
1. using pwnage I created a custom ipsw
2. on iTunes 9, on my pc, I connected via DFU method and my phone comes up ok
3. holding down SHIFT and clicking restore works but it barks at me that "iPhone could not be restored because the firmware file is not compatible
4. i tried under iTunes 8.1 also - no luck either
