Disassembly/Repair of the mobile device Huawei Mate 8 (Huawei Mate 8 NXT-AL10) with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.

⚠️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.

Using a screwdriver (Torx T2), unscrew/drive 2 screws out at the end of the phone.

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and turn it over.

Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.

⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cables and fragile buttons are straightforward to damage.

Pry up the fingerprint sensor connector and remove the back cover. Please use a non-metal or plastic tool because the motherboard is still battery-powered. 

Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw and remove the bracket securing the connectors.

Disconnect the battery connector as soon as possible.

ℹ️️ The Huawei Mate 8 NXT-AL10 model has a battery HB396693ECW with 4000 mAh capacity (aka rechargeable battery).

⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.

Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.

Using a screwdriver (Philips 1.5 mm PH000), unscrew three screws and remove the bracket securing the inter-board cable connector.

Carefully, preferably from the edge, disconnect the connectors and remove the inter-board cable connecting the mainboard to the daughterboard (also known as the sub-board).

⚠️ Be careful when removing the cables from the connectors. The cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.

ℹ️️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.

Disconnect the coaxial cable connector, cable to the loudspeaker.

⚠️ Do not pull on the cable or pry it with a sharp tool. The connectors are pretty weak and break easily, or the cable falls out of the end (lug).

Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.

ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, spring contacts for the vibration motor, and an antenna unit.

⚠️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.

Using a screwdriver (Philips 1.5 mm PH000), unscrew two screws securing the loudspeaker.

Remove the loudspeaker assembly.

Using a screwdriver (Philips 1.5 mm PH000), unscrew 7 screws. Also remove the bracket holding the rear camera connector.

Pry up the connectors of power volume buttons cable, display module cable, rear camera, and coaxial cable.

⚠️ Be careful when removing the cables from the connectors. The cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the board.

⚠️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.

Carefully remove the rear camera. The camera is glued to the display module frame.

Pry up the connector and remove the front (selfie) camera.
