Stick sn 5s4G4J245829
My remote doesn't work after replacing batteries I've looked everywhere for a model number even logged in on my account. the only number I see on the account pertaining to the remote is 5S464J245829
I believe it's a 3600.
Thanks for the inquiry.
As @renojim guessed correctly, your Roku device model is a Streaming Stick 3600X.
