Attempt to put your iPhone into DFU (Device Firmware Update) mode and then restore it using iTunes or Finder. Here's how to enter DFU mode:

  • Connect your iPhone to your computer and launch iTunes (on Windows) or Finder (on Mac).
  • Press and release the Volume Up button, then press and release the Volume Down button.
  • Press and hold the Side (or Power) button until the screen goes black.
  • While still holding the Side button, press and hold the Volume Down button for 5 seconds.
  • Release the Side button but continue holding the Volume Down button for about 10 seconds. If the screen remains black, you've entered DFU mode.
  • Follow the prompts in iTunes or Finder to restore your iPhone.
