I followed the button sequence, I assume it worked because I got the prompt to download, etc. It did the restarts, went to a screen that said something like, current software version is S614 Downloading guide data with a percentage status. When that was done it went to the usual sleep screen. I left it for about an hour in total without touching it. I then checked it, no Carbon UI. I read that disconnecting joey's might be a thing to try, that I did not do. I'll try that next when I have some more time to fuss with it and report back unless anyone has better thoughts.
