Your device or computer might have a hardware issue that stops the update or restore from completing.

1. Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
2. Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
3. Make sure that your security software and settings are allowing communication between your device and update servers.
4. If you still see the error message when you update or restore, contact Apple support.

If you still see the error message, check for outdated or modified software.

Press Sleep/Wake and Home buttons and hold them for at least 10 seconds.

As a final step, try the recovery mode. Turn your device off, then plug it to your computer with the home button pressed.

After that on your computer you should see the iTunes window saying your iPhone needs to be restored to factory settings. Click on the restore button.
