If you see error 9, 4005, 4013 or 4014 when you restore your iPhone, iPad or iPod touch

When you try to update or restore your iPhone, iPad or iPod touch, you may see one of these messages on your computer.

Try to update your device again

If your device disconnects during the update or restore, or if your computer couldn't tell your device to restore, you may 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. Make sure your Mac has the latest version of macOS or the latest version of iTunes.
2. Force your device to restart:

• • iPad models without a Home button: press and quickly release the volume button closest to the top button. Press and quickly release the volume button farthest from the top button. Press and hold the top button until the device restarts. If you're not sure, see which buttons you need to press to restart your iPad.
  • iPhone 8 or later: press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button until you see the Apple logo.
  • iPhone 7, iPhone 7 Plus and iPod touch (7th generation): press and hold both the side (or top) button and the volume down button until you see the Apple logo. 
  • iPad models with a Home button, iPhone 6s or earlier and iPod touch (6th generation) or earlier: press and hold both the side (or top) button and the Home button until you see the Apple logo.

1. Connect your device to your computer using a USB cable. Locate your device on your computer.
2. When you see the option to update or restore, click Update – not Restore – to reinstall the software and keep your personal data.
