Use a suction cup or an iSclack to pull up on the glass and create a slight gap between the glass and the metal frame.

If your display is badly cracked, a suction cup may not adhere. It may help to first cover the display with a layer of packing tape. Alternatively, you can superglue your suction cup to the display.

Carefully insert an opening pick into the gap between the screen and the device to cut the adhesive.

Slide the pick around the sides and bottom of the display to cut the adhesive. Apply more heat as needed.

Work carefully—the glass is thin and will crack easily if you try to force it.

The wi-fi antennas are glued under the screen border along the top edge (on either side of the camera), and can be damaged easily. Use extra care when separating the top edge, and apply more heat if necessary.
