I have gone through the steps on the troubleshooting page and it did not fix the issue. The remote is completely unresponsive and there is nothing I can do to get past the initial setup screen (and I’m still not sure why it reset itself to factory defaults anyway).
It is currently plugged into a USB 3.0 port in the back of my TV but I tried switching to the wall adapter and the same issue occurred.
The device is a Roku Streaming Stick+. If you honestly need the serial number to try and help, I can provide that as well when I get home this evening.
Do you still have the "Long Range Wifi Receiver" attached to the stick+ like the follow:
The Roku remote will not communicate with stick+ without that attached!!
