I need confirmation if my mobo is bricked or not after I downgrade from 4.50 to 3.31 using Instant Flash. The problems that I faced after the downgrade is that it won't POST after restart and there's only 1 long 3 short beeps. I understand that it's a sign of RAM-related error so I took out one stick but there is no changes. Still with the same beeps but when I try put both sticks out, there is no beep and the system will enter restart in loop. So if anyone thinks that it is totally dead let me know as soon as possible.

Perform a full CMOS clear:
http://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal If that does not work then open a support ticket with ASRock and they will advise you on what to do to recover your board: https://event.asrock.com/tsd.asp I always recommend against back flashing to older versions unless absolutely necessary and never when there is a major version number change (4.xx to 3.xx in your case).

I did actually cleared the CMOS according to said suggestion but hopelessly to no avail.
I never downgrade BIOS in any motherboards since Athlon days until now. The reason that made me do this is the board stuck on POST in each restart which needs to be solved by manually forcing it to turn off and back on again. This prompted me to downgrade. By the way, I used Instant Flash and the process completed with no error and only after reboot, it would not POST again like usual. |
