Identify broken contact pad in charging port

Hi, I have this motherboard that has a broken contact pad where the charging port is soldered. I wanna try a jumper if its possible, but I am not sure where I should solder the jumpler wire to.

Look at the picture, from the botton up is the fourth contact pad that is missing.

That pad looks like a ground to me. See the large blue trace? Thats usually a ground plane. Just bridge the pad that is left to the ground or put a jumper between 1 and 3 off what is left of trace. 4 and 5 look common as well. Use flux as solder wont stick as your working with it well.

Thanks for your reply, I just edited my question, I wrote third, but is actually the fourth one that is missing.

Since the charging port you can buy the whole daughter board separately I personally would just stock up on these charging ports.

My bad, didnt paid attention I had selected s4, the motherboard is from a SIII, the GT-I9300I. So, I don't have the option to replace just that part.

I soldered the port back and didn't solder a jumper yet. It charges well, and connects to the computer well, too. I am still wondering what that pin is for, I guess it might be ground after all. However, in the picture Ben shared, it goes somewhere else.
