Not sure if this is the problem or not, I haven't flashed mine since it runs great. Where you downloaded the file at the bottom of thr page it says:
"* Flash utlity may report BIOS part does not
match during flash - this is ok we changed the BIOS part number".
Did you change the update.bat file to match your bin file.
The update.bat file for 8khi1a17.exe file says, (this is the lower part of update.bat):
ECHO Starting flash procedure now.
ECHO Please wait...
ECHO.
AWDFLASH 8khi1a17.bin OLD.BIN /PY /SY /E
ECHO.
ECHO Please restart the computer now!
ECHO Be sure to load "SETUP" or "OPTIMIZED" defaults in the CMOS!
Change the line that says
AWDFLASH 8khi1a17.bin OLD.BIN /PY /SY /E
to
AWDFLASH 8khi2108.bin OLD.BIN /PY /SY /E
And see if that does the trick. If you already did that I don't know what else to suggest.
