Carefully remove the small suction cup from the corner without moving the screen.

Place the small suction cup in the center of the screen and lift to remove screen.

Make sure to separate all glue under the middle parts of the screen as well as the edges - use a thin stiff card to slice through it. Avoid the ribbon cable. Do not attempt to lift the screen until all glue is separated.

The screen is still connected to the rest of the device by a cable, so don't pull the screen up too quickly.
