Report Flirc + Fire TV and URC MX-990 Finally WORK!!! in Remote Controls Posted April 23, 2018 I started this thread, but having moved from Amazon FireTV to Roku Ultra for streaming, I'm no longer using Flirc. I recall lots of difficulty getting Flirc to work with Amazon FireTV but finally did get it to work. Unfortunately,, it came undone over time - not sure why. I am constantly tinkering with a fairly elaborate home theater gear rack, so might have been moi. Decided to abandon FireTV for Roku . . . wish I could help, but am now out-of-the loop.
