I had my father install a RP-2040 in my V2 switch, because my soldering skills are very bad. But my father did a great job. No bridges everything was good. But it just stopped turning on afterwards, I did insert a rcm jig into the rail (Thats probably what ruined it, im a noob) We have tried to replace the battery, flashed the chip, and the chip does light up but the switch just does not turn on anymore.
