    3. Place the suction cup over the Home button (if possible) or next to it (see figure 1). While lifting the screen with the suction cup, insert the hard plastic pick between the aluminum frame and the display frame and press down the aluminum frame. Also use the hard plastic pick to raise the screen (see figure 2). This usually takes several attempts.
    4. As soon as you can lift the screen a few millimeters, you have to carefully work your way around the outside until it’s loosened on both sides (see figure 3).
