JB on 3.1.3, remote wipe and stuck at apple logo
With help from this forum, I upgraded by jailbroken 3.0.1 3GS to 3.1.3 using pwnagtool 3.1.5.
Today, IT was testing remote wipe in Exchange 2003, and wiped my iPhone. Big problem is that it rebooted and has stayed at an apple logo for 5+ hours. I can get it into DFU mode, but that doesnt allow me to restore my 3.1.3 custom firmware back (error 1600). From what I know, the custom firmware can only be applied if in recovery mode.
So, how can I get into recovery mode or otherwise get the phone OS restored? This is a 3GS with the older bootrom, original baseband, and it does have SHSHs on file with Cydia for 3.0, 3.1.2, 3.1.3
