    How did you manage to do that? Nvflash should block flashing vbios with different device IDs. The nongsync is 13D7 and gsync is 1617. This plus the original board ID mismatch should have completely blocked a flash.

    Getting a board ID mismatch but not a device ID mismatch does not make sense, and I can't figure out what you managed to flash onto your card.

    Must have used a flag to ignore mismatch ID.

    That can only be done on special versions of nvflash. Standard versions downloaded from say techpowerup can't do that. The -4 -5 -f flags have not been supported on the standard release in years.

    Need to break out a Skypro Hardware programmer and 1.8v adapter, and a Pomona clip and some jumper cables.
    Then force flash the card back. This always works.

    Drawback is it costs you money.

    Then you can bypass NVflash and just force flash any Bios or the original backup at will.

    (This will not bypass checksum protection of modded Bioses with incorrect checksums, but WILL bypass "falcon" protection from NVflash itself).
