I bought a mintypi v3 kit. Assembled it and found that I had no sound, no select button, and the right direction was not working. Most of the issues were my soldering.

After redoing a few pins with the "wire poke" technique, my sound was back and the select issue ended up being a membrane issue.

The test pad for the right direction and ground had continuity though. I ended up trying to resolve the pins but the connection stayed. I desoldered my pi zero from the minty pcb and cleaned it up but the connection is still happening. I've been told that I messed the minty pcb up and cause a internal short to ground or something. I'm wondering if I can just run a new pad with a wire to the pi zeros pin without it affecting anything?

There is a GND pad right below the RIGHT GPIO pad so somehow it is making contact. What I would do since I think you might have pushed the iron tip through the Right GPIO pad into the GND plane on the other side of the board (this thing is super thin).

Could have also been the "wire poke" that did it would be to use some solder braid to suck any solder on the surface of that pad to see if there is any kind of tiny hole, and if there is then remove a little of the copper around the hole to isolate it from the rest of the pad.

Then you can skip soldering that GPIO (after you test continuity to be sure it isn't grounded anymore) and solder a wire from the GPIO to the Right Test pad and that should solve it.
