Agree with Apple’s terms and the update process starts. The firmware is first saved on your device. When ready light up the display and hit Install Now to start the process, or wait until the 10-second countdown elapses. The device will verify the update and start implementing it. It will automatically restart when the process is completed. Type your Passcode and you’re ready to go!
