The other night I tried updating my BIOS from 2.03 to 2.05 via the Windows batch file. I started by resetting my BIOS to default options, except for enabling the M.Socket3, so that I could launch Windows. An error I got then and continue to get now, unless I run as an Administrator, is an "Incorrect BIOS Image, Please download correct BIOS". I get this error in both Windows and UEFI. I was able to get by this error by running as an administrator, but it appears that it bricked my BIOS on switch 1 as my computer would restart every one second after powering on. 
 
After a little bit of research, I discovered my mobo has a switch for 3 different BIOS. I didn't realize what caused my issue the first time, so I tried the same thing on BIOS 2. Before restarting my computer, the update process resulted in a "Error 317: Hardware sequencing failed. Make sure that you have access to the target flash area!. FTP Operation Failed." Upon restart the mobo would give F2/F9 error codes before failing to post. 
 
After more research, I set my BIOS to 3, swapped the selector to switch 1/2 and tried to update to BIOS 2.03 instead. i had to run both as an admin. BIOS 2 will now power on and display an error '0d' code, with no other activity. BIOS 1 first gave an error "Unable to detect ME disabled", and asked if I wanted to proceed with the flash write operation. Upon doing so, BIOS 1 also gets the '0d' error code and no other activity.
 
Looking through the latest BIOS Update thread, it appears that several people have also had similar difficulties, and that I may need a new BIOS chip. I'm not sure what else I can try. BIOS 3 is the only switch that works (its set to BIOS Version 1.01 and unable to update). I have read that I may be able to create my own bootable flash utility, but I'm not sure how to go about this on Windows 10. And I would hate to brick BIOS 3.

Unfortunately my mobo warrarenty expired two months ago, and having to purchase a new one would be a big pain in the butt. My PC has a custom dual-loop for watercooling, so a new mobo would require a complete tear down of the system.

Would it damage my motherboard/BIOS if I boot into UEFI with BIOS 3, swap the switch to BIOS 1 or 2, and attempt a BIOS update from UEFI?

No.

Sound almost like you are updating the Bios without first resetting the Bios back to the Default Settings.

One thing I learned was to Not update the Bios in Windows any Version.
For Motherboards that do not have a process to update the Bios from within the Bios I use a USB Flash DOS Boot Drive.
