Gear 360 (2016) firmware updates

The two Samsung Gear 360 models (SM-C200 in 2016, then SM-R210 in 2017) are now discontinued. So I don't think you can download firmware updates for them anymore.

I own the older 2016 model and I was trying to figure-out if it had the latest/final firmware. This is what I found:

Aug 2017 = C200GLU0AQF1 

March 2018 = C200GLU0AQK1 

So, I think the "K1" firmware is the final release for the SM-C200 model
