Samsung Soundbar Q80 firmware downgrade

[Passenger]

I have an EU version of this soundbar and I had 1007.9 firmware, but I upgraded it via USB to 1008.0. Now I want it back to 1007.9 (last official release for my country) but when I plug USB with firmware 1007.9 nothing happens because there is newer version 1008.0 (which causes me some troubles, maybe because it's for the USA).

Is there some way to force firmware downgrade?

Bump, same question!

I would like to know too.

I'd also like to know. By the way, could you share your FW file (I'm from France, so this probably is the same I had before upgrading) ?
