[FIXED]3GS can enter DFU but then drops USB connection
Hello - I'm at my wit's end (common I'm sure) with this 3GS. I am not trying to jailbreak, just restore to factory functionality after the phone locked up.
The phone will not enter Recovery mode at all, and in order to communicate with it I have to put it in DFU mode.
When I do, iTunes will see it and tell me to restore. I say OK.
Once iTunes gets to the point where it is "preparing iPhone for restore," the phone will lose its USB connection (dong sound) and never regain it.
Here is, hopefully, a copy of my iPhone updater log file: 2012-03-21 15:48:15.485 [2572:2308]: restore library built Feb 6 2012 at 17:46: - Pastebin.com
Any advice would be appreciated.
Thank you for reading.
