After you restore your iPhone with iTunes or erase it using iCloud, the way to proceed depends on whether you have an iTunes backup, iCloud backup, or no backup. Follow these instructions after you see the white Set Up screen on your iPhone. If the screen is dark and you’re not sure if the restore is finished, press the Home button on your iPhone. If you see the Set Up screen, move on.
If you backed up your iPhone to iCloud before it was disabled and you used iTunes to DFU restore your iPhone, unplug your iPhone from your computer. (It’s already unplugged if you used iCloud to erase your iPhone). Choose Restore from iCloud Backup during the setup process on your iPhone.
If you backed up your iPhone to iTunes before it was disabled and erased it using iCloud.com, choose Restore from iTunes backup during the setup process. If you restored your iPhone using iTunes, choose to restore from your iTunes backup using the Set Up screen in iTunes.
If you don’t have a backup, I recommend you unplug your iPhone from your computer (it already is if you used iCloud.com to erase your iPhone) and set up your iPhone while it’s disconnected from iTunes. You can sync your iPhone with iTunes after you set it up, if that’s what you want to do. (I don’t.)
