Once the screen is warm to the touch, apply a suction handle to the bottom edge of the phone.

If the phone's screen is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

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

Insert an iFlex between the midframe and the screen to create a bigger gap. Leave the iFlex in the gap to prevent the screen from resealing.
