Hi

I have an Intel 14900k and an ASUS ROG Strix Z790-F Gaming WiFi II board.

I have tried to use Flashback to update the board bios before it's powered on.
Nothing in the board just plugged upto the 24 pin motherboard psu cable.

With the bios on a fat32 USB stick renamed the bios file using the bios renamer. The single renamed file is on the root of the usb stick (not in a folder).
Ive tried several usb sticks.
usb 2.0 usb 3.0. Small and large size.
None will work.
When I put the usb stick in the usb port labeled BIOS and power on the psu. Board lights up. I hold the button for 3 seconds. Green icon flases about 4 to 5 times then goes solid.
I've waited over 40 mins and the light doesn't go out. On research a solid green light means a failed attempt.

Can anyone help with this please?

I don't want to boot up the pc without a fixed bios for this chip considering the issues.
And I've no clue if even doing so would damage the chip if booting into bios only to flash the bios the usual way?

Thanks in advance to anyone helping.
 
Just boot to bios and flash it from there , don't worry about the problems as your not putting the CPU under any load and you can check bios what version the motherboard already has.

Just make sure you followed the instructions to prepare the usb drive correctly and try multiple usb ports if not recognised

Thanks. I checked the board and it says 0404. No bios version with that.
Below is what I got with a Google using 0404.

So it's on an early revision.
So I just assume turning on. Straight into bios isn't going to effect any aspect of the chip?
The ASUS ROG Strix Z790-F Gaming WiFi II BIOS 0404 is a 12.88 MB file that was first released on October 17, 2023. Updating the BIOS will also update the Intel ME to version 16.1.30.2264. The ME version will remain updated even if the BIOS is rolled back to an older version.

Just for the future, make sure the usb stick is formatted MBR Fat32 not GPT FAT32, I had the same problem with an ASUS board and this fixed it for me.
