Hi! So the story is. The laptop's battery is dead, so I have tried to update BIOS from recovery mode. Extracted the .fd file from official BIOS updater with WinRaR, placed it on a FAT32 pendrive, and started the laptop with END key + plugging in power adapter to get in recovery mode. When the beeps finished, I have tried to turn it off with pressing power button, but it won't react. So waited for about 15 minutes, still nothing, pulled out power cable. After that, the laptop didn't do anything, can't turn it on, can't enter recovery, it's fully dead, just there is power on USB ports. I have disassembled it, flashed downloaded dumps to the SPI chips, and tried to turn it on. Still nothing. What I have missed, why it's not working? Any help is really appreciated.
flash with spi programmer the bios chip and a good .bin dump. ohh u have.. umm did you make a backup.bin of original broken ? what programmer?
The BIOS chips were empty, so I have tried many dumps, none of them worked. Programmer is flashrom with rayer_spi. Is it possible to reflash KB9012 using the USB ports? The programmer doesn't detect it after connecting to keyboard connector.
rayer spi.. unstable. Kb9012 not sure.. likely needs Rt809F programmer or something better than rayer home made.. try ch341a cheap
