You may opt to carry out a standard restore, recovery mode restore or DFU mode restore in iTunes for that matter. In order to get started, you would need to secure a computer, either Mac or Windows PC with the latest version of OS and iTunes software installed.

  4. Click the option to Restore your iPhone to factory defaults or from a previous iOS backup file.

With your iPhone connected to your computer, force restart it with these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side/Power button when you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo since you’ll need to enter recovery mode.

Your very last resort of all else failed to get your iPhone 8 Plus back to life is a DFU mode restore. It’s regarded as the deepest type of system restore you can do on your iPhone.

  3. While your phone is connected, press and hold the Side/Power button for about 3 seconds.
  4. Keep pressing on the Side/Power button then press and hold the Volume Down button for about 10 seconds. If the Apple logo appears, it means you’ve held the buttons too long and that you’ll have to start all over again.
  5. If you see no logo, release the Side/Power button but keep holding the Volume Down button for another 5 seconds.
  6. If the screen stays black afterwards, it means that you have successfully entered DFU mode. At this point, you will be prompted with an alert message on your computer saying that iTunes has detected your iPhone. If you see that message, follow the onscreen prompts to complete the DFU mode recovery process.
  7. If you see the Plug into iTunes screen, it means you haven’t entered DFU mode and that you will need to start all over again.

Note that entering DFU mode requires timing so if you failed on your first attempt, don’t hesitate to try again from the start until you get there.

What to do if iTunes still doesn’t recognize your iPhone 8 Plus even when it’s connected?

If iTunes doesn’t recognize or failed to detect your iPhone, check and ensure your connections are secured. You can try removing and re-inserting both ends of the USB cable or Lightning connector or switch between different USB ports on your computer. If that still failed, then your iPhone needs service.
