Mobo stuck on postcode AA, how to flash BIOS directly?

When new mobo arrived, it started once, I normally entered UEFI and then restarted to reinstall OS. And it beeped a few times and stuck on postcode AA with blank sreen. HD spun up and PC restarted after pressing random keys. After a week of trying and killed GFX, I've decided to go for extreme measures - to flash mx25l6406em2i-12g chip. What IC programmer I should use or maybe something else wrong? Unfortunately, RMA isn't possible.

Take out the CMOS battery for 5-10 minutes and then put it back in. It's the circle sized thing left to the postcode, about the same size of a coin.

Only on beginner level. Anyway, I got it to boot(pulled out CMOS battery for half an hour) and it again jumped straight into BIOS. After that - same problem. Maybe it wants boot device? Also, chipset is Q77
