    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

    5. Use a spudger to disconnect the connector and then remove the flex cable.
  8. Removing the battery

    1. Bend the remaining flex cable to the side using your finger. Then slowly soften the glue underneath the battery by heating the battery with a heat gun.
    2. Use a broad spudger to carefully lever out the battery from all sides until it comes out easily.

    Distribute the hot air evenly and heat the same spot several times instead of risking punctual overheating of the battery. You shouldn't need too much force for the spudger.

  9. Inserting the battery

    5. Press down the black battery flex cable to make it stick. Do not connect the battery yet!
    6. Connect the large flex cable with the arrow to the motherboard.
