iPhone 3GS 3.1.2 will not reboot after unlocking with Sn0w!

[dozer123]

Hello,
I need some help here if you folks don't mind. I have an iPhone 3GS running 3.1.2. I jailbroke the phone with Blackra1n and it worked perfectly. Downloaded Cydia and Rock from the Blackra1n app. Those worked fine. Well, then I decided to install Sn0w and it installed and went back to my springboard but could not find service. So.... I restarted the phone and now, it's just the black screen with the silver apple and it won't do anything else. Tried plugging it back into the computer and the computer doesnt even recognize that the iPhone is plugged into it. I have done a soft reboot and it's still the same thing. Anyway, PLEASE help me! Thank you so much!

re-run Blackra1n

Just tried that but it just says waiting for device like it doesn't recognize the phone is plugged in

Putting it in DFU mode will not do anything. In fact, Blackra1n does not work in DFU mode, since the hack used requires exploiting a USB weakness in iBoot.

DFU Mode Worked!!

Putting it in DFU Mode made iTunes recognize the phone again!! It restored to it's original settings and backed up my phone from a previous sync. Thank you so much for your help!

Oh, and I used Blackra1n again to jailbreak and installed Cydia and Rock, and everything is working perfectly. I'm just not going to use Sn0w to unlock it.

The OP did not jailbreak his phone in DFU mode.

You two seem to have a "thing" going at each other.

Neither of you needs another time out !

I apologize. Perhaps I misunderstood. Since your comment was in response to the OP's inability to run blackra1n, I assumed you meant to run it in DFU mode.
