Disassembly/Repair of the mobile device Xiaomi Mi 10 Lite (Xiaomi Mi 10 Lite M2002J9G) 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 card 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.

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 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.

Using a screwdriver (Phillips 1.5 mm PH #000), unscrew the ten screws.

Pry over the edges. Move an opening tool along the edge detach the clips and remove the cover with antenna pads and tracks.

ℹ️️ 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.

ℹ️️ The Xiaomi Mi 10 Lite model has a battery BM4R with 4060 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 PH #000), unscrew the seven screws.

Pry over the edge and remove the loudspeaker assembly with antenna tracks.

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.

Pry over the edge and remove the cover for cameras with a flashlight.

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

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.

With extreme care, remove the battery because it is glued from the inside by the manufacturer.

The brown tag has instructions written on it.

Also, we need to remember or look in advance at the location of the flat cables under the battery, so as not to damage them.

Disconnect the coaxial cable connector, fingerprint sensor cable connector.

⚠️️ 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 may be glued to the frame or attached with attachments like latches or hooks, so be careful.

ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, 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.

Disconnect the two coaxial cable connectors. Pry over the edge and unstick the small board.

ℹ️️ In the display frame remained: the earpiece speaker, vibration motor, fingerprint sensor, and three coaxial cables.
