Apple has changed the way to restart your iPhone with the release of the iPhone 8, iPhone 8 Plus and iPhone X. This has also changed how you put your device into Recovery Mode since you need to restart your iPhone. Here's how to enter Recovery Mode with the iPhone 8 and iPhone 8 Plus:
- Connect your device to your iTunes-connected computer using your Lightning to USB cable.
- Press and release the Volume Up button then press and release Volume Down button. Press and hold the Side button for ten seconds, continue holding the button even after the Apple logo appears. Release the Side button after the Connect to iTunes logo appears on your iPhone display.
- Launch iTunes on your computer. You will see the message, “There is a problem with the iPhone that requires it to be updated or restored.”
- From here you can choose to Update or Restore your iPhone.
