If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Once the screen is warm to touch, apply a suction handle to the left edge of the screen and as close to the edge as possible.

Lift the screen with the suction handle to create a small gap between the digitizer and the frame.

Insert an opening pick into the gap between the digitizer and the frame.
