First things first: check Apple's support documents

If you see any of these error codes when your iPhone won't restore from iTunes or iCloud, try checking Apple's own support documents first to learn what to do. There are a few easy fixes you can perform for yourself.

Force restart your iPhone

Force-restarting can fix so many software glitches, so whenever you face a problem that makes the iPhone not restore, you can carry out this action and see if that will take care of the issue. A force restart won't erase your data, and the way you need to do it varies depending upon which iPhone model you own.

On iPhone 8 and newer: Press and then quickly release the Volume Up button, press and then quickly release the Volume Down button. Then press and hold down Power button. Keep holding the button until you see the Apple logo appear.

On iPhone 7: Hold both Volume Down and Power buttons. When the screen is displaying the Apple logo, release both buttons.

On iPhone 6s and earlier: Hold the Power button and the Home button at the same time until the Apple logo appears.

Update iTunes

It's possible for iTunes to interfere with the normal iPhone restore process. As such, it's worth checking the iTunes and updating it to the latest version if needed. This will help you discover if an old version of iTunes problem is to blame.

  • Open iTunes.
  • From the menu bar at the top of the iTunes window, choose "Help".
  • Click "Check for Updates."
  • If an update is available, follow the prompts onscreen to install the latest version.

If your iTunes is up-to-date but the computer keeps saying your iPhone can't be restored or updated, try the next method.

Restart computer

In some cases, you can also try rebooting your computer to fix an iPhone that won't restore. It's possible that the operating system or a hardware driver has stopped working, which prevents your iPhone from restoring. If that's the case, obviously, a restart is the easiest option.

Use recovery mode

There's a feature inside iPhone called recovery mode that allows you to put the device into the mode to run and connect to iTunes while not totally booting up the iOS. This is really helpful if your iPhone is not restoring.

The method to enter the recovery mode differs between iPhones. Here's how to do:

1. Open iTunes or Finder on your computer.

2. Plug your device into the machine.

3. Wait until the recovery mode screen appears.

  • On iPhone 8 later: Press then quickly release the Volume Up button. Press then quickly release the Volume Down button. Press and hold the Side button until your device gets into recovery mode screen.
  • On iPhone 7 (Plus): Press and hold the Side and Volume Down buttons at the same time until the recovery mode screen appears.
  • On iPhone 6 or earlier: Press and hold both the Home and Side (or Top) buttons simultaneously until you see the recovery mode screen.

4. A window pops up in iTunes prompting to Update or Restore the phone. Choose Update. Then your computer will try to reinstall the iOS firmware onto your device without wiping any data.

Use system repair program

Try a different cable

Another possible reason why an iPhone won't restore is a hardware issue. If you are stuck in a restore and update loop that fails every time, check to ensure that the Lightning cable is plugged in firmly. You might want to try a different Lightning cable. Please noted that not all Lightning cables are created equal, make sure your selection is MFi-certified.

DFU restore your iPhone

If your problem is still not fixed, DFU (Device Firmware Upgrade) restoring your iPhone is your last resort. It's a more difficult and destructive restore option — You will need to press a combination of buttons on your device to enter the DFU mode, and the restore process will delete all your personal files, apps and customizations and reset the device back to clean state.
