Gigabyte AX370 Gaming 5 Motherboard Issue after BIOS Update

[jas.folsom]

I'm having an issue with my Gigabyte AX370 Gaming 5 motherboard. It started out with my Main BIOS not posting after updating to the latest BIOS. I ended up switching over to the Backup BIOS and it worked fine. The mistake I made was accidentally updating the Backup BIOS instead of the Main BIOS so now neither one boots. I've tried clearing the CMOS, unplugging the battery, etc. Nothing seems to work. Anyone have any suggestions. I'd really love if I could figure this out and didn't have to request an RMA.

You may want to try and describe the method you used to flash the BIOS and someone may be able to tell you what step(s) you did wrong.

or you could try flash it straight on bios chip or solder chip and use spi programmer. do you know is it a 8pin chip?
