Rest the heated right edge of the phone on something that is about 0.5 inches (13 mm) thick. This angles the phone for the opening tool.
Brace the left edge of the phone with your fingers so that the phone won't slide. Pull on the suction cup with firm pressure.
Press the edge of an opening tool into the seam between the back cover and the frame.
Slide the opening tool back and forth along the seam a few times.
