Brand new Roku Ultra LT started setup, as soon as we had it connected to wifi it said there was an update. Clicked "ok" and it restarted the set up process but this time the remote will not connect. It keeps trying to pair but it's just an unending circle of "pairing" and no response. I have tried unplugging everything, removing batteries and starting everything over. It is not connected to wifi, so using the phone app won't work either. Never had so much trouble setting up a Roku. Please help.
