Using the T5 or T6 screwdriver, remove the six screws from the back of the phone, as shown in the first image.

Remove the back half of the phone by using the plastic opening tool to pry apart the top half from the bottom half. Wedge the plastic opening tool tool around the edge of the phone to dislocate the tabs.

Once the tabs are dislocated, pull the back of the phone apart from the front half.
