This is for anyone trying to update their bios using the Asus EZ Flash Utility.
There is an error in the manual, which says rename downloaded bios file to A8R32-MVP. It should actually be A8R32MVP. After using correct name the new bios installed without problem.
Thank you for posting the information.
What is surprising is the fact that Asus have released more than 1 update to the manual to download as a pdf file... yet, as far as the english version, they still include the mistake that you have already seen.
