- Then you must locate the charging port, in our experience there are only two possible configuration modes. The first where the port is integrated into a small flexible plate made up of other elements. In the second, the port is soldered to the motherboard of the cell phone.
First flexible plate method.
It is very simple to change this plate, you must remove and place the one you bought new. It may be a bit expensive, but it will be worth it.
Second method port integrated to motherboard.
This case is more complex than the previous one, however, if you have patience and you follow the steps you can do it yourself.
You must have work tools as a fine tip tin soldering iron and heat gun. You will need to get the following items: gel flux, tin, Kapton thermal tape (this will protect the cell phone circuits from heat), and a mesh to desolder tin.
You will proceed to protect the close connections to the port with the tape completely covering them. The connections between the plate and the port will be covered by the flux and then you will proceed to supply heat with the gun, this will melt the tin. Subsequently, the port is removed with the forceps, very carefully. The excess tin on the plate is cleaned, for this you must use the flux and the desoldering mesh applying the tin soldering iron.
Now, you can solder the connections one after another by placing the port in its original position. To avoid interference you should check the neatness of the work. Done this, you will assemble the cell phone again.
