I'm sorry, I can't help you with any of what you're requesting. It happened far away from me in my parent's home, and I am always the first point of contact for their technical support. Octogenarians do not understand that a rechargeable remote that looks just like their supposedly-lost remote adds a microphone to their TV experience. That new piece of hardware talking to their previously-working and properly-set-up TV launches a voice remote setup assistant.
All they wanted to do is control their TV, they had no interest nor desire to add a microphone to their internet connection. None of us are the least bit concerned with how it functions. None of us want this feature, and they are incapable of operating it correctly even if they did. I'm saying nothing they wouldn't fully agree with. They don't know enough about technology to understand what they bought. But they follow my instructions very well.
The voice remote setup assistant can not and will not let you quit it. No manner of power cycling either with the remote or the wall outlet will let you escape it. You can unplug the TV overnight, drive the remote to another county, leave the remote by the roadside, come home, plug the TV in, turn it on, and you're right back in the unquittable setup assistant right where you left off. This is not an instruction I gave them. This is something they did all on their own and told me about later.
Where this applies to me is... I set up the email account, payment, and roku account FOR THEM because they don't understand technology. I gave them all the subscriptions they wanted and I signed them in as HOTEL. The way they had to fix this was with a GeekSquad appointment. Competent enough because that fixed it, BUT... I never gave them the account password. I have absolutely no idea how, but they've managed through that appointment to still be signed in after a factory reset. Perhaps the TV stored all of my settings? I don't know if it did that or not? Somehow now they're signed in as HOME, and they're hitting my credit card with thousands of dollars worth of purchases so far. I hope I get to see them again this year. I've changed account settings, reset passwords, I can't stop them from doing it.
Really. Please. Put a "I Disagree" on that setup assistant that quits it with a warning that says, "you will not be able to use the voice feature on your new remote until you enable it in Settings/Remote". It's simply the presence of the voice remote that launches that assistant. You should be able to repeat this using any non-voice Roku TV, and then pointing the voice remote at it and hitting a button. Try to exit without the reset button... I dare you.
