Introduction

This guide shows you how to repair a defective display for your P9 lite. This fix is necessary if the glass is cracked, no longer responds to touch, or the LCD is black or flickers.

Back up all your data before the repair, and touch something metal, like a radiator to get rid of any static charges.

30 steps
  1. Switching off your device

    P9 lite - Switching off your device 02

    Before the repair, you should switch off your device to avoid short circuits during the repair.

    1. Press and hold the standby button until the shutdown dialog appears on the screen.
    2. Tap to confirm.
  2. Removing the back cover

    P9 lite - Removing the back cover 04
    P9 lite - Removing the back cover 05

    The back cover of the Huawei P9 Lite is clipped in all around the display unit.

    1. Attach the suction cup relatively far down. Then pull on the suction cup to lift the back cover.
    2. Then insert the pick between display unit and backcover and pry them apart.
    3. Release the back cover clip for clip around the entire device. If it doesn't work the first time, you can use a second pick or pull it a little harder with your fingers.
    4. The back cover is glued to the fingerprint sensor. You can use a heat gun to slightly heat the back cover and soften the glue.
    5. Once all the clips are released, you can remove the back cover.
  3. Removing the mainboard cover

    • 9 × Phillips
    • Fingerprint sensor
    • NFC connector

    There is a humidity indicator over one of the screws. You can try to remove it and put it back later, but it usually breaks. So you can simply pierce it with a screwdriver.

    1. The cover is secured with Phillips screws. Unscrew all screws and store them safely.
    2. Lift up the cover a bit.
    3. Attention: Several cables are attached underneath.
    4. The cover is clipped in, once at the camera and once at the side. Gently move the cover to release the clips. Then unfold the cover to the side.
    5. Using a spudger, carefully pry off the connector of the fingerprint sensor flex cable.
    6. Remove the glued contact of the NFC antenna. If necessary, heat it gently using a heat gun and then carefully pry it off using a spatula.
  4. Disconnecting the battery

    P9 lite - Disconnecting the battery 01
    • Battery connector

    Now disconnect the battery to avoid short-circuits.

    1. Use a spudger to carefully pry off the connector of the battery flex cable.
  5. Removing the speaker

    P9 lite - Removing the speaker 02

    The screws have two different lengths. Store the screws separately to insert them correctly afterwards.

    1. Remove the Phillips screws on the plastic cover.
    2. Carefully remove the speaker and the attached cover: Slide a thin tool into the opening on the lower edge of the device and pry out the speaker.
    3. Now you can take out the speaker.

    2. Pry very carefully, or you might tear off the sockets from the PCBs!

    3. Remove the antenna cable.
    4. Use a spudger to carefully pry off the connectors on both sides of the large flex cable with the arrow.
    5. Remove the flex cable.
  7. Removing the battery

    P9 lite - Removing the battery 01
    P9 lite - Removing the battery 02
    1. Slowly soften the glue underneath the battery by heating the battery with a heat gun. Never heat the battery directly.
    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 use too much force for the spudger and don't pry from one side only, as this will bend and break the battery.

  8. Removing the SIM card tray
