i picked up the bios file from
https://www.asus.com/fr/support/(https://www.asus.com/fr/Motherboards/ROG-STRIX-Z370-H-GAMING/HelpDe... and i downloaded the .zip file on the downloads folder and extracted it with right click extract to usb which was previously formatted as fat32 using diskpart --->format fs=fat32. i also tried with winzip to check if it wasn't the extraction of the file the rootcause.
At this time i m not sure from where to download the bios file and also if i m at the correct bios website. I also have heard i should use 7zip to extract the bios file.
the bios thats currently flashed on the system is the 1801 and i would like to flash the 1704 but apparently it is impossible to downgrade. I m nearly certain i have a bad bios file on the system i should be able to reflash….
I hope i ve given enough information,
with kind regards,
Arnaud
PS: i m flashing using the utility in the bios itself. if you know another method then i ll be glad to know it thank you
