Step 1.
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.
ℹ️ 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.
Step 2.
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.
Step 3.
Using a screwdriver (Phillips 1.5 mm PH #000), unscrew the ten screws.
Step 4.
Pry over the edges. Move an opening tool along the edge detach the clips and remove the cover with antenna pads and tracks.
Step 5.
Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.
ℹ️ The Xiaomi Mi Note 2 model has a battery BM48 with 4000 mAh capacity (aka rechargeable battery).
⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.
Step 6.
Using a screwdriver (Philips 1.5 mm PH #000), unscrew the eight screws.
Step 7.
Pry over the edge and remove the loudspeaker.
Step 8.
Pry up the connectors of the side buttons cable, display module cable, inter-board cable, and coaxial cable.
⚠️ 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.
Step 9.
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.
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.
Step 10.
Disconnect connectors on the motherboard and remove the main and front (selfie) cameras, and assembly with an earpiece speaker, microphone, proximity sensor.
