i had a Roku TV set up for using the antenna tv only for my elderly next door neighbor. I told her I could get her more channels with the Roku fully set up. Now the antenna and Roku live tv app are combined and she doesn’t like all those channels. She wants it back to how it was before. I tried to reset to factory settings and it asks for a PIN. I tried the only one I knew and it doesn’t work. I don’t know what to do.
