Re: GIGABYTE GA-990FXA-UD3 rev. 1.0 BIOS Rollback failure
look at your CPU Supported list for your Motherboard, would you happen to have any of the CPU's listed to work with the F1 bios? if so, pop it in, if not try to borrow one to get your system to post and then update your bios to the newest bios (Or at least greater than F3). second resort would be to try a local computer shop, they should have a spare CPU in the right family, they'll charge you for the service but should be a sure thing.
then failing those then I'd perform the Dual Bios recovery from this post; How to fix "dead" dual BIOS motherboard if flashing failed
reason it's a last resort is if you slip you'll blow your motherboard and possibly also lose the warranty too. if you have steady hands then it's worth a try.
