I am afraid is not possible to roll back to 0132 or earlier BIOS version:
“Due to structural changes in this BIOS version, once a board has been converted to this version or later, it will no longer be possible to downgrade the BIOS to version 0132 or earlier."

Is it possible to see if the Intel® Processor Diagnostic Tool can identify the version properly after a complete uninstall – reinstall process of the latest version?
