Also ensure that your computer runs on the latest operating system that is compatible with your iPhone 12. If all requirements are met, connect your device to the computer using the Apple-supplied USB/lightning cable. Then allow iTunes to sync with your iPhone and backup files, if possible.

  1. Press and release the Volume Up button quickly.

Follow the onscreen prompts to complete the procedure. Do not disconnect your phone and keep it connected until the entire restore process is finished.
