This in not fun work. I used powerful magnification, and the smallest soldering tip imaginable. I turned my heat down to the lowest effective setting. Slowly, I established a solder droplet on what part of the traces that remained. then, get solder on the connector pads. Plop the connector on top and sneak the soldering iron onto the conductors one at a time while pushing on the connector with a screwdriver. Give yourself a few hours -do not rush It can be done.
