Switching off your device
Switch off your device. Press and hold 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
2 × 2,8 mm P1 Pentalob-Schrauben

Unscrew and remove the two screws at the bottom of the device that keep the enclosure closed.
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.
