Disassembly/Repair of the mobile device Xiaomi Mi 11 Lite (Xiaomi Mi 11 Lite M2101K9AG) 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.

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.

Using a screwdriver (Philips 1.5 mm PH000), unscrew 13 screws.

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

Disconnect the battery connector as soon as possible.

ℹ️️ The Xiaomi Mi 11 Lite model has a battery BP42 with 4250 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.

Remove the loudspeaker assembly with antennas.

Pry up the connector and remove the long serpent cable with a holder for cards.

Disconnect the inter-board cable connector.

Pry at the edges, turn over the sub-board. Disconnect attached to the sub-board the coaxial cable connector and remove the board.

ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, spring contacts for the speaker, 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 and remove three rear cameras and one front (selfie) camera.

Pry up the connectors of power volume buttons cable, display module cable, inter-board cable, and two 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.

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.

ℹ️️ In the display frame remained: the earpiece speaker, battery, and vibration motor.
