Resolve iOS update and restore errors in iTunes

When you use iTunes to update or restore iOS on your iPhone, iPad, or iPod touch, you might see an error code or alert message. Most of these errors happen because your computer has older versions of software or can’t connect to the server.

You can fix most update and restore errors with a few simple steps. Try these first:

Update iTunes.

Get the latest version of iTunes on your computer.

Update your OS.

Install available updates for your Mac. If you have a PC, you can get PC software updates from the Microsoft website.

You might need to update, change, disable, or uninstall software that’s causing an issue.

Unplug extra USB devices.

Keep only your iOS device, keyboard, and mouse plugged in directly to your computer.

Restart.

Turn off your computer and your device. Then turn them on again.

Try again.

Update or restore your iOS device again.
