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.
â ī¸ 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 display module
â ī¸ Pay attention! Disassembly has a maximum 3rd difficulty because the process begins with the disassembly of the display module. If you have no experience or are not sure of your skills, we strongly recommend that you contact a specialized service center.
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.
âšī¸ī¸ The surface of the display module 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.
The process can be seen in our video entirely so as well as in detail, at the end of the instructions.
Step 4. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw and remove the bracket holding the connector.
â ī¸ Should say, this model was repaired before, came to us with one screw at this place, but obviously, there is a second hole. So you may have two screws that need to be unscrewed.
Step 9. Disconnect the battery connector
Disconnect the battery connector as soon as possible.
âšī¸ī¸ The Xiaomi Black Shark model has a battery BS01FA with 4000 mAh capacity (aka rechargeable battery).
â ī¸ 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 11. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew four short screws.
âšī¸ī¸ 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 13. Remove the loudspeaker
Remove the assembly of a loudspeaker, vibration motor with antennas.
Step 14. Disconnect the connectors
Disconnect the coaxial cables connectors, cable to the mainboard, on the daughterboard.
â ī¸ 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 15. 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.
âšī¸ī¸ The sub-board contains a charging port (Micro USB), microphone, spring contacts for the speaker, vibration motor, and an antenna unit.
â ī¸ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 19. Disconnect the connectors
Pry up the display module cable connector. Turn the motherboard over and disconnect the coaxial cable connector.
Step 20. 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.
â ī¸ 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.
