Disassembly/Repair of the mobile device Xiaomi Redmi Note 8 Pro (Xiaomi Redmi Note 8 Pro M1906G7E) with each step description and the required set of tools.

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.

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.

ℹ️ 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 the 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.

Pry carefully up the bracket holding the fingerprint sensor connector.

Pry over the edge and remove the cover protecting the cameras. Also, in this cover integrated the fingerprint sensor.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 10 screws.

Remove the cover with antennas. The cover protects the printed circuit board. Try to lift the cover by the edges and not push anything between them to not accidentally touch or short-circuit anything on the circuit board.

Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.

ℹ️ The Xiaomi Redmi Note 8 Pro model has a battery BM4J with 4500 mAh capacity (aka rechargeable battery).

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

Using a screwdriver (Phillips 1.5 mm PH000), unscrew five screws.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew two long screws.

Pry over the edge and remove the loudspeaker and cover with antennas.

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

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.

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

Disconnect the coaxial cable connector.

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

The sub-board, also, may be attached with attachments like latches or hooks, be careful.

ℹ️ The sub-board contains a charging port (Micro-USB), microphone, headphone jack, spring contacts for the speaker, 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.

Pry up the connectors of the display module cable, sensor cable, 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.

Pry up the connectors and remove the four rear cameras.

Disconnect the connector on the motherboard, and remove the front (selfie) camera.

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 circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.

The motherboard, also, may be attached with attachments like latches or hooks, be careful.

⚠️ 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.

ℹ️ In the display frame remained: the earpiece speaker, battery, coaxial cable, and vibration motor.
