Prop up the heated edge of the phone on something that is about 0.5 inches (13 mm) thick. This will angle the phone so that the opening tool is easier to insert.

Lift the back cover's right edge with your suction cup, opening a slight gap between the back cover and the frame.

This may require a significant amount of force. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

If you're using an iOpener, follow the heating instructions to avoid overheating it, or the gel pack may burst.

Press the edge of an opening tool into the gap.

The rear glass can break if you use too much force or attempt to pry with metal tools.
