Roku Stick stuck in an update loop but not connected to wifi
I'm trying to connect a new-to-me Roku streaming stick but repeatedly getting an Error 003 "Can't Update" message after it starts up. The options I'm able to select on this screen are "try updating again" and "cancel." I haven't been able to connect the stick to my wifi so of course it can't update. If I select "cancel" a purple screen appears with the Roku logo quite small in the upper left corner of the screen and nothing else. From here there is no onscreen response to any remote commands although I can hear the button push registering--the little doot noise sounds on the tv speakers with each button push.
The very first time I booted it all up I was taken through the correct set-up screens but my wifi wasn't functioning properly and roku couldn't connect. It was at this point that it attempted to update and got stuck in this loop.
The device is not yet associated with my account and I have no IP address for it because it's not connected to internet. I'm unable to access settings or any other function via the tv. I've rebooted it a good 15 times with same outcome and taken the batteries out of the remote and repaired it a few times too just for good measure. No dice. Anyone familiar with this? Anything else to try?
