Yea, tried to discharge the motherboard, taken out CMOS battery too, it didn't help. I don't know if this is programmer related or not, I have reflashed 2 types of BIOS SPI chips with it, EN25QH16 and W25Q32BV. But these chips are maybe different from KB9012's debug interface. I can't get a CH341A for now, maybe some months later. It would be good to recover the laptop if it's possible with the tools I have currently, but not very urgent. Here is the programmer's config, if it helps: https://github.com/flashrom/flashrom/blob/master/rayer_spi.c
