Hi all I hope im doing this correctly,
I need a firmware dump for the Nuvoton NCT6687D‑M controller (EC flash chip: W25X20CLNIG) used on the MSI B660M Mortar DDR4 (MS‑7D42, revision 1.1).
I acquired a ch341a black to reflash my bios, and was so excited to use it that I tested it on the W25X20CLNIG 3.3v chip as I didn't have the 1.8v yet for the bios chip itself.
Being a total newbie I straight up corrupted the EC flash chip, and now the power button does nothing, PS_ON# does not change, and when I manually short the PS_ON# pin it immediately turns off when I stop shorting.
The chip still works, after trimming the cheap soic8 clip I now have a reliable connection.
If anyone has a working dump from the same board, I would be very thankful.
