What are you using to remove the solder? I sometimes find that I need to use a combination of solder removal techniques. Most often I use an electric solder pump that heats the solder and sucks it out. Other times I have to use solder wick. Sometimes both.

Is it double-sided PCB? Does it have a solder mask (i.e. a coating over the traces, usually green)? Are the holes still filled with solder? If so, you might try adding a bit of solder to the pad and then removing it, along with the old solder.

Feel old, blind, and like shit.

Don’t. It happens. A lot.
