⚠️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device Xiaomi Mi 11 (Xiaomi Mi 11 M2011K2G) with each step description and the required set of tools.
Step 2. Remove the tray
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.
Step 3. Open the back cover
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.
Step 5. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 3 screws.
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. Open the cover
Pry up the connector and remove the cover with antennas, flashlight, NFC tag.
Step 7. Disconnect the battery connector
Disconnect the two battery connectors as soon as possible.
ℹ️️ The Xiaomi Mi 11 BM4X model has a battery TLp030K7 with 3000 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.
Step 9. Remove the loudspeaker
Pry and turn over the loudspeaker assembly carefully because the coaxial cable is attached from the inside.
Step 10. Remove the small board
We need to remove the loudspeaker, but the coaxial cable is attached to the small board which is fixed to the loudspeaker. So, there are two options for us.
The first one is to disconnect the connector and release the cable attached to the small board.
The second one is as we did, unstick the small board, and put it into the display module frame (coaxial cable still attached to the board).
Step 11. Remove the inter-board cables
Carefully, preferably from the edge, disconnect the connectors and remove two inter-board cables 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.
Step 12. Disconnect the connectors
Disconnect the coaxial cable connector, under-screen cable, 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 13. Remove the daughterboard
Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.
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.
Step 14. Remove the battery
Please read the description on the brown tag. First pull out tags A and B, then pull UP! the tag A.
Step 16. Unscrew one screw
Using a screwdriver (Philips 1.5 mm PH000), unscrew one screw securing the motherboard.
Step 18. Remove 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.
