I finally got an S19, but it turned out to be an S19i. The Braiins download page lists it as supported, but it doesn't work and isn't mentioned elsewhere in the docs! I tried the SD, "Unknown variant of am2-s17 platform". The file/software should maybe-kinda reflect that it's for an S19, btw. 
Tried the Toolbox, "Unsupported". I contacted support, but after doing some digging, that seems like a wasted effort now, as I've seen others mentioning that it still doesn't work. I ended up using Vnish, just to get some control over it. I've even read a bit of the mudslinging back and forth between the two on here and it certainly doesn't fill one with confidence, lol. I'd prefer to be using Braiins, but they don't seem to care about the little guys and things appear to be slipping! 
I had even replied back to their feedback email last year, which got read a couple of times, but totally ignored. Not even a token "Thanks", which sadly isn't a first either.
Simply put, if Vnish works and Braiins doesn't, that's egg on the face.
