Step 2

Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible.

Lift the rear glass with the suction handle to create a gap between the glass and the frame.
Insert an opening pick into the gap.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
