I have a 4200X-Roku 3 streaming box with an RF remote and today, it reprogrammed itself. It might have been after update to firmware 9.3.0, but I'm not sure.
Press the home button, it launches Netflix, press it again, it launches Hulu, press it again, it goes to home screen. The back button (left arrow next to the Home button), when pressed it no longer goes back to previous screen, it launches Rdio instead. Rdio no longer exists, but there is a function button for it on the remote. Repeated pressing just re-launches Rdio, never does the intended function.
I tried to reset the streaming box and the remote, re-pair it, new batteris etc. per official instructions but nothing helps. Any ideas how to fix this? Only way I can now control the Roku is now via a smartphone app.
Back in the day UEI made radio shack and One-for-all universal remotes use to come down with a scrambled keypad, being so programmable as they were there was fix for those remotes. The roku remote is probably done with, sorry.
