I can't update my ipod touch 5th generation to iOS 6.1.2
iTunes says it has detected my an error and need to restore. I tried to restore few times, it give me the same messages.
Maybe:
Restore loop (being prompted to restore again after a restore successfully completes)
Troubleshoot your USB connection. If the issue persists, out-of-date or incorrectly configured third-party security software may be causing this issue. Please follow Troubleshooting security software issues. .
Next try placing in DFU mode and then restoring.

Then try restoring on another computer.
Last, make an appointment at the Genius Bar of an Apple store.
