    1. Put your iPhone 5s 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 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. Do not lift the display more than two centimeters to avoid tearing the Home button cable below it.
    5. 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).

    If the display is disconnected, only lift it a little bit. The Home button cable connects the display to the Lightning connector. This cable can tear if you lift the display too much.

    1. Remove the silver cover over the Home button connector by placing the pointed tip of the spudger slightly below the cover and lifting it out (see figure 1).
    2. Now you have to disconnect the contact from the connector.Carefully pull it off using the laboratory spatula or spudger.
    3. Once the cable is disconnected, you can lift the display at the Home button. Note that the LCD/touchscreen cables are still connected to the logic board (see next step).
