Disassembly/Repair of the mobile device Xiaomi Black Shark 3 with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

⚠️ Pay attention!

Steps 2 to 5 are about removing the display module. We need it when we want to remove the motherboard.

If you don't want to remove the motherboard, please, skip to step 6.

⚠️ 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.

ℹ️️ 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.
