    Press the Wake and Home button while still holding them for like eight seconds, then release the Wake button while still pressing the Home button till your computer acknowledges your iPhone.

  • iPhone 7 or iPhone 7 Plus:

    Press the side and the volume down buttons for eight seconds before releasing the side button but continue pressing the volume down button up to when your computer acknowledges your iPhone.

  • iPhone 8 or newer models:
