No, my friend, FF code in power on means total fault
Hardware is not in fault, 100% sure
Excuse me for asking... but are you sure that the .BIN file is not corrupt?
I have error with official awdflash.exe and video message "Wrong BIOS size - Bios don't fit in this EEPROM" is very very strange, what do you thing?
I have compared original and mod BIOS: 512 KB (524.288 byte) = identical size!
