Re: Roku 3 4200x Ultra suddenly stopped working, hard reset fails to clear
Roku model 4200 is a Roku 3, released in 2013. Ultras are different models, all released since then.
In your 3rd item: Roku terms your "hard reset" a "Factory reset". I don't know if it will help, but to initiate a Factory reset you must hold the reset button in at least 30 seconds.
