Back speaker and vibration not working after USB board replacement

Hey, I replaced the charging connector’s USB daughter board, and after that, the vibration and the back-speaker, which are both connected to this board, don’t work.

However, charging works fine.

I’ve tried with 2 different aftermarket replacement boards, and I’ll keep trying more as long as this seller sticks to their “replacements only” policy.

Any tips?

(Also, it’s the M01, not the A01, but we don’t have the M01 listed on this site yet.)
