@Tomasonx, Hello, what is the problem exactly? just use a soldering iron, use flux and solder and remove the potentiometer.
Or you can use a fan if you have a soldering station... personally I just removed it with a soldering iron. Just fill that potentiometer with melted solder (all 3 contacts) and then just move it away from the board. Hope it helps :)
After it is done solder the wire like on the picture
everything according to the circuit

@Tomasonx, yes only point 3 (Output). You can use a magnifying glass to check visually. You can use a multimeter to check if you don't have a short circuit between VCC, GND, and Output. If you want to check more you can follow that PCB trace (it is probably going to IC), you can test if it has good contact.
I have already tried on 3 pieces of DRV8825.
Can you detail the process and possibly check if the soldering was correct?
