This only works for certain motherboards that have support for flashing the BIOS from USB without a even a cpu or memory populated.
I'm not sure, but think that functionality requires at least some part of the previous BIOS to be intact.
If this solution doesn't exist/work, you will need to go the route of finding the (often undocumented, sometimes unpopulated) SPI flashing header, and using an external device to directly write a working BIOS onto the SPI flash chip.
