How to disassemble LeEco Le Max 2, Step 1/1 How to disassemble LeEco Le Max 2, Step 1/2 How to disassemble LeEco Le Max 2, Step 1/3 How to disassemble LeEco Le Max 2, Step 1/4

Step 1. Open the tray

⚠️ Before disassembling, don't forget to turn your phone off.

Using the Key tool (aka Needle) or Paperclip, open the SIM and Memory cards (Micro SD) tray and take it out.

⚠️ Pay attention! The tool must be inserted into a special hole on the edge of the phone's housing. Do not press too hard. It may break the tray ejection mechanism.

Step 2. Open the display module

⚠️️ 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.

ℹ️️️ The surface of the display module must be heated to soften the adhesive underneath. The approximate heating temperature is 50 ° C.

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.

⚠️️ It is important not to get a film between the touchscreen/glass and the display module, which will damage the module.

⚠️️ Look in advance at the picture of the places where the touchscreen and display cables pass under the display module to avoid accidental damage.

Step 8. Open the cover

Remove the cover with antennas and earpiece speaker that 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.

ℹ️️ On the cover, you can see the metalized coating on the plastic in the form of tracks and contact pads. These are Wi-Fi, Bluetooth, and GPS antennas.

⚠️ It is important while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.
