Can't Restore iPad - Error 9
I'm hoping someone can help me. In the middle of syncing my iPad with iTunes, it failed and the iPad began endlessly rebooting. It never got past the Apple logo.
I managed to put it into recovery mode and attempt to restore. When restoring, I got an error 9 indicating a USB issue. I followed all of the troubleshooting steps (http://support.apple.com/kb/TS1286) recommended by our Apple friends. I tried different cables, and I tried a different computer.
I run Windows 7 - 64 bit. All of my software (OS, iTunes) and drivers (Apple mobile USB driver) are up to date. I did not Jailbreak my iPad. I play by the rules.
During the restore process I watched the USB driver in the device manager. I could see it pop in an drop out, and always at key times in the restore process. It dropped out for the last time after the iPad began displaying the progress bar.
My feeling is that it is not a hardware problem since it occurs so predictably in the restore process, and never prior to starting the restore.
I think error 9 is reported by default as the most available error to trap, but I don't think it is the cause.
A lot of people seem to have this problem, but I have never seen a posted solution. Any help is very much appreciated.
Thank you.
iPad, iOS 5.1.1
