  3. Apply a suction cup to the heated edge of the back panel by pressing down on it to create suction, as close to the edge as possible. If your back glass 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 panel.
