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

Apply a suction handle to the screen as close to the center of the right edge as possible.

Pull up on the suction handle with a strong, steady force to create a small gap between the frame and screen.

The large screen is very fragile. Only create a gap big enough to insert an opening pick.

Insert an opening pick into the gap.

Don't insert the pick more than 5 mm to avoid damaging the screen.
