FC: MillivoltOSD v2
RX: R-xsr
VTX: TBS Unify 5v 

I had a flying quad with FlightOne on board. Everything was ok, but I wanted to try FalcoX, so I flashed the board and installed it. Right after powering up with FalcoX on board my VTX start to emit red, solid light. Also had problems with buzzer, and that my modes and VTX settings wouldn't save. 

So I flashed FC back to FlightOne...but my VTX is still on channel A1 and has solid, red light on. I am trying to push and hold the button on Unify for a few seconds - red led turns off. But with every new power cycle it turns on again. It's not a PIT mode, because I can move away for 10-20 meters and still have vision in goggles. When I connect the battery with button pushed, PIT mode turns on (as I can see from about 1m range.

I can't change the channel by FlightOne software now (it was possible before flashing it). 
For now I have horrible experience with that software... and it is soooo poor documented. 

Can anybody help?

Here is my dump.

I don't really know anything about FlightOne, but could these lines be the problem?

vtx_power=0 means it's the first option so 25mW, but I will try set it to 1.

I just checked with spare FC (the same MillilvoltOSD) which is not configured (and that hasn't been flashed at all). Unify still shows red light.

EDIT:
Yeah, nothing changes. It looks like a problem with VTX. It's bricked in some way, but it works on A1 still.

Small update:
Red and blue LEDs indicates unlocked VTX. So FalcoX automatically unlocks it.

Next thing: current beta of Falcox (4 10.0.4.1220) has many problems like buzzer always beeping and as my case shows - problems with configuration save. Tried alpha version instead and gained control over VTX by OSD and Smart Port. No idea about switching channels through a button on Unify - I don't want to change anything too soon if it works. Will try for a few days
