microUSB charging port needs to be replaced

Droid mini is older, I can see the pins of the micro USB charging connector bent/worn under a microscope. First, i was able to get it working by denting the male part of the cable, but that only lasted a few weeks. I see on other directions how the motherboard is removed. Do you have some words on the unsoldering/resoldering of the connector ?

Also, I seem to have a hard time finding a part number and where to order it. I had no problem with finding it for my Droid Razr (also broken, will use as a test case)
