Step 2. Remove the tray

Use the Key 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.

ℹ️️ Remember the location for the SIM and Memory card (Micro SD) trays so that nothing is confused when reassembling.

⚠️ 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.

Step 3. Open the back cover

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it. 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 cable and fragile buttons are straightforward to damage.

⚠️ Look in advance in the picture for the cables’ location for inter-board, touchscreen, display, buttons (if any) under the cover to not damage them accidentally.

Step 4. Unscrew the screws

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 10 screws at the phone's upper part.

⚠️ Try not to touch the camera. The camera is quite fragile! If you leave prints or other marks on the lens, it will be difficult enough to clean the lens, and the quality of the images may deteriorate.

⚠️ Also, be careful not to damage the protective shell of the phone battery in any way. This battery MAY CATCH FIRE OR EXPLODE.

ℹ️️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Step 6. Disconnect the battery connector

Disconnect the battery connector as soon as possible.

ℹ️️ The Huawei Honor 9S DUA-LX9 model has a battery HB405979ECW with 3020 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. Disconnect the coaxial cable connector, cables to the mainboard, and inter-board sub-screen cable on the daughterboard.

⚠️ 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).

Step 10. Remove the sub-board

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

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

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