Hi all, i bought a second hand asus motherboard that for some reason has the non-wifi bios (v2603) on it (maybe some tech flashed the bios with a SPI), my question is, how can i revert that, and how secure will be that procedure??

My Motherboard is the Asus TUF z390 Plus Gaming (Wi-Fi), and yes, it has the Intel CNVi card installed in the back, so im 100% sure is that one.

Thanks in advance.
 
Thanks for the repply, Tried that but didn't work, what else i can do?

Update bios to the latest would undo whatever they did.


Copy extracted file to fat32 formatted usb stick, no folders, just copy file to usb stick. No need to rename the file. Then run the bios flash utility in the bios.
 
Guess the only way is to use it like this, or flash it back with a SPI. But I'm sacare to death hehehe.

In the other hand, what's the risk on updating to the latest firmware version? Right now I'm using the 2603 and at the Asus website are 7 up ahead mine.

What do u think?
 
Are you running Win 11 currently? If not, updating bios for that reason alone would be advised.
Right now I'm using Win 10 22H2, and my GPU doesn't support Res bar, so won't be able to use that functionality, should I upgrade to Win 11 ?

I'm Cuban by the way.
 
Your board supports Win 11, for when support for 10 ends later this year. Installing/upgrading to Win 11 requires tpm to be enabled in bios, if not enabled manually already, latest bios would have it enabled by default.
