Was having issues with, 6400mhz ram, was only stable at 5400mhz max. Reading up and noticed the Bios was at 803, new current was 1505. Using Asus tool flashed the 1505, upon reboot stops at code 10.

Is there a way to recover this motherboard?

As above, try USBflashback with a FAT32 formatted pendrive.

If using EZFlash, make sure the system is at complete defaults. Could possibly be a bad flash.

In researching the Bios flash, opened up the file in a hex app to compare what I flashed it with from the first download to the second download! Sure enough, there was a significant difference in the last bytes. All my previous efforts using Flashback method failed each time, although it appeared as if it completed correctly. But still it would not boot, just showed the red LED flash on 7F then on to 10. This last time, after making sure the downloaded flash was intact, Flashback did work!

Thanks for the response.
