    Be very careful during this step.

    1. Place the suction cup as far down on the back cover as possible, for example where it says “Huawei.”
    2. Pull on the suction cup while using the pick to push the display against the table. As soon as a gap appears between the display and the back cover, you can carefully insert the pick.
    3. Move the pick along the edges to disconnect the back cover from the sides. Continue to pull carefully on the suction cup.
    4. The fingerprint sensor is installed in the back cover. A flex cable connects this sensor to the motherboard. Be careful when you take off the display to avoid damaging the cable or board.

    5. Carefully lift the back cover. Slowly fold open the device at the upper edge like a book. Now you should see the fingerprint sensor flex cable.
  5. Disconnecting the fingerprint sensor
