I purchased a Roku Steamibng Stick 4k this morning. This is my second such stick in my home. After plugging it into my TV and the power into the TV's USB port the display prompted me to enter my Wi-Fi password, which I did and it was accepted. It then progressed to a setup menu that is in Spanish. I don't speak Spanish. I am unable to get to a Settings menu because the device is apparently still trying to link to my TV and or my remote. I see an option "Obtenar Ayuda".
How do I get to the Setting menu to change to English?
Since you're just starting with the setup, press and hold the reset button on the edge of the stick with the power connected for no less than 30 seconds. That should get it to factory reset and you can try again.
As a note, some TVs can't supply enough power through their USB ports to power Roku devices, so in the event that any weirdness occurs, the first thing to try is using the supplied power adapter plugged into the wall.
