Remove six silver .3 centimeter screws from the top, bottom, and sides with the T4 Torx screwdriver.

One silver screw will be hidden by the sliding mechanism. Once you have removed the screw visible on one side, slide the mechanism over to reveal the other one.

The four screws on the top and bottom may not be visible. If your phone is new or has not been taken apart before, the four screw tops will be hidden by little circular stickers. These can be peeled off with tweezers.
