    1. Put your iPhone 5c on a soft, clean surface to avoid scratching the back.
    2. To lift the front panel, you need a suction cup and the hard plastic pick. If the screen is severely cracked, cover all of it with packing tape.
    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 plastic frame and the display frame and press down the plastic 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 (see figure 3), you have to carefully work your way around the outside until it’s loosened on both sides (see figure 4).
