The point on PCB is totally vanished and I cannot solder a wire to it anymore. Even if I somehow stick it the putty terminal doesn't show any serial activity. Is there any alternative TX point that I can use or is there any way to make this point alive? I even tried to rub that portion with a sandpaper a bit but no luck.

Please advice me what should I do now? The router still works in same bricked behavior (all LED's light up).
I've attached an image. The hardware version is V4.21.
