Inleiding

Use this guide to replace the display assembly including the frame of your Huawei P9.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

  1. First switch off your phone and remove the SIM card tray. Unscrew the two Pentalobe P2 screws located at the bottom next to the device's USB C port. If the screen is cracked you might want to use some tape to protect your eyes from glass shreds and get a better grip to open the phone.

    • Free the ends of the adhesive pull tabs to get a good grip on them.

    • The battery is secured with three pieces of adhesive, a removable pull-tab in the center, and on the SIM tray side. A third piece of adhesive on the button side has no pull-tab.

    • Pull the adhesive tabs in a slow constant movement to free the battery.

    • Should those adhesive tabs snap, you might want to use an iOpener to heat and soften them a little bit so you can pry out the battery with a spudger.

    • There are two cables running directly underneath the battery. Take care not to damage them when prying with a spudger! You can see their position in the last picture.

    • Slowly lift the battery toward the button side and free it from the remaining hidden piece of adhesive.

    • When reassembling your phone replace old adhesive with double-sided tape or pre-cut adhesive strips.

  16. Remove the antenna cable and  the power and volume bottom cable on either side. Inspect the new part carefully and compare it to the old one. There might be some small parts that have to be transferred. On the back of the motherboard there are thermal pads (pink rubber-like gobs) for heat dissipation. If these thermal pads broke, are too dried out or stick to the old display assembly you might need to apply new thermal pads to the new display assembly or the motherboard.
