Disassembly/Repair of the mobile device Huawei P30 Pro (Huawei P30 Pro VOG-L29) with each step description and the required set of tools.

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

We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.

ℹ️️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.

Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.

Do not use a lever or any force for separation that could damage the elements inside.

Do not let the liquid get inside the smartphone. The process can be seen in our video entirely so as well as in detail, at the end of the instructions.

⚠️ Look in advance at the picture of the places where the touchscreen and display cables pass under the display module to avoid accidental damage.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the 10 screws and remove the bracket holding the connectors.

⚠️ Try to control and perform all actions carefully so as not to accidentally touch or short circuit anything on the printed circuit board.

If the screws are different: 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.

Remove the cover with an NFC tag and antennas that protect the printed circuit board (PCB). Try to lift the covers by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

ℹ️️ On the upper cover, you can see the metalized coating on the plastic in the form of tracks and contact pads. These are Wi-Fi, Bluetooth, and GPS antennas.

⚠️ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.

Disconnect the battery connector as soon as possible.

ℹ️️ The Huawei P30 Pro (VOG-L29) model has a battery HB486486ECW with 4200 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 (Phillips 1.5 mm PH000), unscrew 7 screws at the lower part of the phone.

Remove the cover protecting the daughterboard (aka sub-board). Try to lift the cover by the edges and do not push anything between the cover and PCB to not accidentally touch or short-circuit anything on the board.

Carefully, preferably from the edge, disconnect the connectors and remove the inter-board cable with a charging port 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 cables connectors, cables to the fingerprint sensor, and loudspeaker cable connector 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).

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.

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 microphone, 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.

Carefully remove the loudspeaker.

Pry up the connectors of the display module cable, coaxial cables.

⚠️ 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.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw securing the motherboard.

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.

Remove the bracket, disconnect connectors and remove the rear cameras and one front (selfie) camera.
