In the last post, I labeled the ch341a backwards by accident because I was sleep deprived, and now I feel embarrassed at myself for making people feel decieved when looking at my post for help. So, I'm reposting to fix the image diagram. This motherboard has a Windbond 25Q128JVSQ chip. I put a multimeter to the proprietary SPI interface pins from the motherboard (left of the chip) so you don't have to. You only need 6 pins to read and write to the chip. Ch341a black V1512 was used. With it connected, you can downgrade, mod, or update your firmware, etc.
