Step 1 — Back Cover

Image description: A Huawei P9 smartphone is shown with a screwdriver being inserted into the bottom edge near the USB-C port.

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.

ℹ️ 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.

Step 2

Image description: Two images show the Huawei P9 being opened. The first shows a suction cup tool attached to the screen. The second shows the phone being gently pried open, revealing internal components.

⚠️ Avoid lifting only the display instead of the whole phone assembly, as doing so may cause damage to the screen.

Use an iSclack or a suction handle to separate the phone assembly from the rear panel.

ℹ️ In case you can’t manage to lift the phone assembly out of the rear panel, you can insert the pointed end of a spudger into the headphone jack opening and press the phone assembly upwards until you create a gap between the assembly and rear panel. Then use the spudger to lever the phone assembly out of the panel.

⚠️ Don't remove the rear panel completely yet. There is a cable connected to it, running from the fingerprint sensor to the display unit.

Step 3 — Fingerprint sensor

Image description: A close-up view of the phone's interior shows a spudger being used to disconnect the fingerprint sensor cable.

Disconnect the fingerprint sensor using a spudger.

Step 4 — Battery

Image description: A sequence of images shows a spudger unplugging the battery connector, and a hand removing a sticker from a screw on the battery assembly.

Unplug the antenna cable.

Remove the sticker that sits on top of the screw.

Step 5

Image description: Two images show the removal of a metal plate securing the battery connector. Screws are removed, and then tweezers are used to lift the plate.

Unscrew the two Phillips #00 screws that hold the metal plate in place.

The plate, which covers the battery connector, has two small hooks on each side. Use a tweezer to free them and unhinge the plate by carefully moving it upwards.

Step 6

Image description: A spudger is used to unplug the battery connector. Another image shows an NFC antenna being carefully peeled off the battery.

Now you can unplug the battery connector and bend it aside.

The EVA-L09 model has an NFC antenna adhered onto the battery.

ℹ️ If you are just removing the battery to get to the display, you can leave the NFC on the battery.

Mark its place on the battery with a felt pen for reassembly. Carefully peel it off and make sure not to rip or crease the antenna.

For reassembly, place the NFC antenna on the battery where it was before so its contacts align with their counterparts.

Step 7

Image description: Fingers are shown carefully pulling the adhesive pull tabs from the battery.

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

Step 8

Image description: Multiple images demonstrate the process of pulling the battery out using adhesive tabs. A final image highlights the location of cables beneath the battery.

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

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

ℹ️ 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 stretch release adhesive strips, double-sided tape, or pre-cut adhesive strips.

Step 9 — Display

Image description: The motherboard is shown with several Phillips #00 screws being removed, and flex cables being disconnected.

Remove the other five Phillips #00 screws from the motherboard.

Disconnect the motherboard flex cable as well as the power and volume button cable.

Step 10

Image description: The LCD screen flex cable is shown being unplugged from the motherboard.

Unplug the LCD screen flex cable.

You can now remove the complete motherboard easily.

ℹ️ Conveniently, both the front and rear cameras are removed with the motherboard.

Remove the earpiece speaker (mind adhesive underneath).

Step 11

Image description: A heat gun or iOpener is being used to apply heat to the top edge of the Huawei P9's display.

Heat the top part of the glass with a heat gun or iOpener.

ℹ️ The glue used for the display is tough and needs patience and gentle steady force.

Step 12

Image description: A spudger is inserted into the camera bay to pry the display away from the frame. A plastic card is then inserted between the screen bezel and the frame to prevent re-adhesion.

When the glue is softened, insert a spudger through the camera bay in the midframe and push the display away from the frame.

Place a plastic card or two opening picks under the display bezel at the top, between the screen and the frame. This will prevent the glue from readhering.

Step 13

Image description: Opening picks are shown being slid along the side edge of the display to separate it from the phone's frame.

Insert an opening pick approximately 1/16 of an inch and slide it along the side to separate the display from the frame.

ℹ️ You might feel more resistance where the LCD ends on the lower end.

Stop here and take your time to reheat that part and soften the glue.

Step 14

Image description: Opening picks are carefully moved around the bottom corner and along the bottom edge of the display.

When the glue is soft enough, carefully move the pick around the bottom corner.

You can now work your way along the bottom edge.

Leave the opening pick on one side and flip the display over.

Step 15

Image description: The display flex cable is detached from the frame. The old display is lifted away. A small rubber gasket near the speaker grill is highlighted.

On the back side, detach the display flex cable from the frame.

Now you can lift the display away from the frame.

Check for any small parts like the rubber gasket at the top behind the speaker grill.

To reassemble your device, follow these instructions in reverse order.
