Unplug all cables from your phone.

Completely power off your phone.

-
Adhesive secures the perimeter of the back glass to the frame.

Place a suction handle at the bottom edge of the back glass, as close to the edge as possible.

Push down to attach the suction cup.

-
-
Pull up on the suction handle with strong, steady force to create a small gap under the back glass.

Slide the opening pick back and forth along the bottom edge to separate the adhesive securing it.
-
-
-
Remove the back glass.

Now is a good time to test your phone before sealing it up. Power it on and check that it works. Power it back down before you continue reassembly.
