If you see error 9, 4005, 4013, or 4014 when you restore your iOS device

When you try to update or restore your iPhone, iPad, or iPod touch, you might see one of these messages in iTunes.

Try to update your iOS device again

If your iOS device disconnects during the update or restore or if iTunes couldn't tell the device to restore, you might see one of these messages: 

  • The iPhone [device name] could not be restored. An unknown error occurred (9).
  • The iPhone [device name] could not be restored. An unknown error occurred (4005).
  • The iPhone [device name] could not be restored. An unknown error occurred (4013).
  • The iPhone [device name] could not be restored. An unknown error occurred (4014).

Try these steps:

  1. Install the latest version of iTunes.
  2. Force your device to restart:
    • On an iPhone 7 or iPhone 7 Plus, press and hold both the Sleep/Wake and Volume Down buttons for at least ten seconds, until you see the Apple logo.
    • On iPhone 6s and earlier, iPad, or iPod touch, press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.
  3. Connect your device to your computer using a USB cable. 
  4. When iTunes ask you to update or restore, click Update (not Restore) to reinstall iOS and keep your personal data.

If you can't update, try these steps

If you can update, but your device starts up in recovery mode, follow the steps above again. On step 4, choose Restore instead of Update. After the restore completes, you need to set up your device from a backup.

If you continue to see an error during the update:

  1. Check for updates to your Mac or PC. If you restart your computer for an update, check for updates again after you restart.
  2. Try to restore your device using another USB cable.
  3. Try to restore your device on another computer.
