I need a little help with my BIOS updating. I was about to update my BIOS on my Maximus IV Extreme-Z (Z68) motherboard from version number 0210 to the latest version, which is number 3603. So I downloaded the 3603 BIOS update, formatted my 512MB USB stick to FAT32, extracted the BIOS update file (the .ROM file) onto the USB and restarted my computer and got in to the EZ Flash 2 utility. But when I was going to select the .ROM file, it said that "Selected file is not a UEFI BIOS".
I thought that was a little strange, so I searched for the problem on the internet, and I contacted ASUS chat, and they all said that the problem was caused by not formatting the USB to FAT or that they forgot to extract the .ROM file. But I did all this already (I have checked, many times), so the formatting or extraction is not the problem in this case. I also have the right BIOS file, because I entered my motherboard serial number onto the ASUS download support thingy, so I know that is not the problem either.
Anyhow, I kept looking on the internet, and I came across the Flashback option. Where you stick your USB to the ROG connector on the rear end of your motherboard, and you flash the BIOS that way. But now, here is the question; should I dare to use the Flashback utility instead of the EZ Flash 2? Will my motherboard brick if I use the Flashback, even if the EZ utility said that there was something wrong with my BIOS update file? Or do you have any other tips on how to update my BIOS?
A little expertise would be extremely helpful!
