Sorry that was a typo. I can't seem to be able flash any modded BIOS with any tools I've found. Flashback doesn't even work with a stock BIOS, I wonder if there is a BIOS setting I'm missing or it's my USB (3.0) drive.
That's what I thought, I'm going mad looking for one as we speak! Will update when I get there. Thanks for your help.
Doesn't work with Flashback. There seems to be some sort of new security implemented... when I try and flash with EZupdate or ASUSupdate in windows (I know I shouldn't) it says something like "The integrity of the bios image has changed" Any ideas what is going on?
