Hello, I bricked my bios when the spi flasher disconncted mid libreboot install. I've tried multiple bios files from this thread and changing the mac address etc but nothing works, the power button just blinks 3 times when connecting charger, any help with getting a working bios would be much appreciated.

Thanks in advance...
