I jailbroke my 3GS yesterday with Blackrain and I updated to 3.1.2. Today, my phone just turned itself off and it comes up with the appled logo for about 10 seconds and just goes off. I have tried putting it into DFU and recovery mode but when I try to restore via Itunes it comes up saying failed and then just goes back to recovery mode. I downloaded the iPhone2,1_3.1.2_7D11_Restore.zip file but how to I manually select this via Itunes. I have done where you press shift but how do I save this zip file into a IPSW. Or do I need a custom restore for blackrain...Help I'm confussed.
