    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.

    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.

  10. Inserting the battery

    Make sure that all required small parts (seals, etc.) from the old display are installed and that the protective films are removed.

    1. Lift the flex cable to insert the battery into the new display.
    2. Press down the battery on the adhesive strips.
  11. Connecting the flex cables and the antenna cable

    • Antenna cable
    • Flex cable 1
    • Flex cable 2
    • 1 × Phillips

    Make sure that all connectors are properly in place before you press them in, or they might get damaged.

    1. Place the large flex cable with the arrow between the two circuit boards.
    2. Connect the connector to the lower circuit board. Make sure the arrow shows up (towards the motherboard).
    3. Place the bracket plate over the connector, latch it in, and use the Phillips screw to fasten it.
    4. Connect the antenna cable to the lower circuit board. First lead it around the vibration motor. Then position the plug straight over its socket. Then press down the plug using a spudger until it snaps into place. (Repeat this step at the other end of the antenna cable, if it isn't connected.)
    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.
    7. Connect the middle flex cable to the motherboard.
    8. Place the bracket plate over the connectors of the two large flex cables, latch it in, and fasten it with the Phillips screw.
