[flashrom] Re: ENE KB9012QF A3 reflash help needed

[Nyúlós Lónyál]

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:
