Apply a suction cup to the display, near the middle of the left edge.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

If the screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool.

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.
