Disconnecting the connector is strongly advised to prevent any potential short circuits during disassembly.
Additionally, make sure to carefully unplug the connector for the rechargeable battery without using a metal tool.

We heat the phone cover, the temperature is about 70° C , to facilitate disassembly

Turn off your phone before beginning disassembly.
Step 2:

Use the paperclip or key tool (also known as a needle). Pull the SIM and Memory card (Micro SD) tray out by inserting the tip all the way into the hole till the tray ejects.
Keep an eye out! On the edge of the phone's housing, there is a hole that the tool must fit into. Keep your pressure moderate. The tray eject mechanism could become damaged.
Step 3:

We advise utilizing a specialized heating tool such a heating mat, heat gun, or separating machine. It will make the procedure simpler. You can use a hairdryer at home, but you'll need to manufacture or have on hand a special nozzle to gently heat and concentrate the heat flow where it's needed.
To loosen the glue below, the back cover's surface needs to be heated.
The heating temperature is roughly 70° C.
For separation, use a pick or a thin plastic film. You can use isopropyl alcohol to speed up the procedure. Passing the tool between the pieces that need to be split is frequently extremely tough. Away from the FFC cables or buttons, pick the far edge.
Avoid using a lever or any other force to separate objects that could harm the components inside.
Step 4:

Remove the 17 screws with a Phillips 1.5 mm PH000 screwdriver.
Step 5:

Carefully remove the speaker and antenna-equipped middle cover.
Step 6:

As soon as you can, disconnect the battery connector.
