Use a T3 Torx screwdriver to remove the sixteen 5.0 mm‑long screws securing the back cover.

Use your fingernails, or angled tweezers, to remove any stuck screws.

The screws are secured tightly in the back cover, so you might not be able to remove all of them. If you can't remove a few screws, don't worry! Move to the next step and follow the guide normally.
