Apply a suction cup to the center of the screen's top edge, as close to the edge as possible.

If your screen is badly cracked, cover it with a layer of clear packing tape to help the suction cup adhere. Alternatively, you can pull using very strong tape instead of a suction cup. If all else fails, try supergluing the suction cup to the broken screen.

Insert a Jimmy in the earpiece speaker cutout at a downward angle.

Pull up on the suction cup with strong, steady force while simultaneously prying up with the Jimmy until the Jimmy slides under the digitizer.

Significant force is required on the suction handle—you don't need to pry hard with the Jimmy. If you're having trouble, apply more heat and try again.
