Secure a suction handle to the bottom edge of the screen, as close to the edge as possible.

If the screen 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 phone assembly with the suction handle to create a small gap between the assembly and the back cover.

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 in a steep angle into the gap you created. This might require some force.

Slide the opening pick to the bottom right corner to slice the adhesive and release the plastic clips holding the back cover in place.
