@Techguy2024 while it's certainly possible your Roku has finally died, it also could just be the remote. One way to test it is to see if the Roku app on a phone or tablet connected to the same network can control it. If the app works, then it's probably your remote.
However, I have to point out that a new voice remote is going to be $20-30, and a new Roku Express 4K+ is currently on sale for $30. So for roughly the same cost of a new remote you can get a new player that supports 4K/HDR and is miles newer and better performing than your 4200 (which is now more than 11 years old). My guess (and that's all it is) is that Roku will drop support for the 4200 within the next year, and an upgrade will likely be necessary at that time.
I believe the way it works is X it came in a brown box sold online, R was retail in store in a pretty box, and I think B was refurbished. They are all the same thing.

Nope, I have X models that came directly from Roku, and pretty sure I have at least one X that came from a retail store. RW was Walmart, although I'm not certain any of these are still applicable.
