If you can still enter the BIOS, do it there. It's the old fashioned and most reliable way

 

You can flash an older version of the BIOS, with the same procedures as flashing a new version of BIOS.

Guys, I just plugged my USB, and in Ez flash. It doesn't see the file. (but It can see the sandisk drive in Bios)

 

Does this mean that Asus prevents us from downgrading to lower version? Is it still a good Idea to downdrage via USB flashback?

 

This is insane.

You need a USB Stick with a version of DOS. AFAIR Rufus can do that.

Then you need the Flash Programm for DOS.

And with that it should be doable.

With the internal tools, yes they do.

But there is the good old way usually.
