Problem w/Micro B USB 2.0 5pin female
You have not damaged the PCB, just melted the connector from what I can tell. 

Replace the connector, clean all the pads up with solder braid gently, you want no solder left on them to make fitting the new one as easy as possible, I would probably even remove that LED when you fit the new one, 

When you do get the new connector, ignore the center pad, if all you have is an iron, the edge pads will have to do,

Start by aligning the 5 pins, and then tack one of the 4 edge pads to hold it in place, once your happy, tack an opposite corner,

With all this done, heat from the edge or the top of the usb pins, go slowly 1 at a time, only adding small amounts of solder for each, 

Once that looks good, secure the 4 corner pads with a decent amount of solder and you should be back in business.
