How do I downgrade firmware version of the mmRH-3608? (How to downgrade instead of upgrading)

[Onin]

Hi ~

I am looking for answers on how to downgrade a version of Lynx Firmware (mmRH-3608). I would really appreciate if I could get help.

Let me explain my situation, I have three modules.
    1) PXIe-5840 (ver: 17073118)
    2) NI-5692 (ver: 17073118)
    3) mmRH-3608 (ver: 17080411)

I did upgrade by using "Lynx Firmware.exe" (ver: 1.0.0.10)
After updating, the version of mmRH-3608 will be upgraded as follows.
    1) PXIe-5840 (ver: 17073118) - same
    2) NI-5692 (ver: 17073118) - same
    3) mmRH-3608 (ver: 18052917) - upgraded

But now I want to revert back to the original firmware version, but I do not know how.

It looks technically possible, but it can make the downgrade impossible by the product or software. It would be best to officially ask the hardware manufacturer.
