Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap you created.
