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

If your screen 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 handle. If all else fails, you can superglue the suction cup to the screen.

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

Insert an opening pick into the gap between the midframe and the screen, to the right side of the earpiece speaker cut-out.

Leave the opening pick in place to prevent the adhesive from resealing.

Don't try to move this opening pick to the top right corner of the screen. There's a plastic pin on its rear side holding the display in position and blocking the way of the opening pick.
