11 steps

Switching off your device
Turn off your device holding down the power button until a menu appears. Select “Power off” and tap again to confirm.
Removing the SIM card tray
Insert your SIM tool into the little opening on the tray to unlock the tray.

Remove the SIM tray and, if applicable, the SIM and microSD cards.
Removing the enclosure screws
Unscrew and remove the two screws at the bottom of the device that keep the enclosure closed.
2 x 3.1 mm T2 Torx screw
Lifting the display
Put the suction cup as far down on the display as possible, for example where it says “Huawei.” If the glass is too cracked for the suction cup to generate a vacuum, you can cover the display with tape.

Pull on the suction cup while using the pick to push the back cover against the table. As soon as a gap appears between the display and the enclosure, you can carefully insert the pick.

Also move the pick along the edges to disconnect the display on the sides. Continue to pull carefully on the suction cup.

The fingerprint sensor is installed in the back cover. A flexible flat cable connects this sensor to the motherboard. Be careful when you take off the display to avoid damaging the cable or board.

Carefully lift the display. Slowly open the device at the short upper edge like a book. Now you should be able to see the connection cable.

Disconnect the cable from the motherboard by carefully inserting the spudger below the contact and disconnecting it.
Disconnecting the battery contact
Remove the two screws that hold the black plate in place.
2 x 2.3 mm PH00 Phillips screw

Disconnect the plate from the motherboard. The plate is hooked on in three places. Insert the tweezers below the plate and carefully unhook it.

Disconnect the battery contact from the motherboard. Carefully insert the spudger below the contact and disconnect it from the socket.

Removing the control buttons
Disconnect the plug contact for the control buttons from the motherboard.

The control buttons are glued to the display frame on the side. Insert the steel laboratory spatula between the frame and the cable to detach the glue. Start with the individual button. The cable’s very delicate.

Then disconnect the other two buttons from the frame.

Remove the cable.
Installing the control buttons
Stick the control buttons back on the enclosure frame. Make sure the little openings in the cable go over the tabs on the frame.

Press the entire cable firmly onto the side of the frame so the glue will stick.

Connect the plug contact to the board.
Connecting the battery contact
Connect the battery contact to the motherboard again by carefully pressing the contact into the socket with your finger until you hear it click into place.
Battery contact

Put on the black plate to hold the contacts in place. Hook it onto the board.

Fasten the plate with the two screws.
2 x 2.3 mm PH00 Phillips screw
Installing the display
Put the back cover at the short upper edge of the display and carefully connect the fingerprint sensor’s contact. You have to hear the contact click into place.

Close the device by folding down the back cover and pressing on the display.
Fastening the enclosure screws
Use the two screws on the bottom of the enclosure to close the device.
2 x 3.1 mm T2 Torx screw
Installing the SIM card tray
Put the SIM tray and any cards back in your device. Make sure the tray is positioned properly.
