I get error message (-1) when I'm trying to update an iPod Touch that had belonged to someone else. I cannot erase the software.
Mac mini (Late 2012), OS X El Capitan (10.11.4), cannot update iPod Touch
You may need to do a Update or Restore on the iPod touch using recovery mode
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
Error (-1)
Try on another computer
Also see:
iOS: If you can't back up or restore from a backup in iTunes
Then see:

If still problem that means a hardware problem. In that case make an appointment at the Genius Bar of an Apple store.
