I need help in de soldering and placing my new replacement ..I can’t seem to find help on this topic i dont want to buy the whole cable with usb port i wanna solder a new one in
will, I suggest you use this teardown to disassemble your phone. It is not a guide, but does give you a general idea on how to get it accomplished. Remove the logic board. Desolder the data connections from the micro USB port on the front. Desolder the four points that hold the port to the logic board from the back. Remove the port and replace with a new one, available at places like this. Reassemble your phone. Hope this helps, good luck.
One quick Q… which are the data pins that are for the ground from left to right?
