Look for reset button, or pinhole and do a factory reset of the device. If its a stick you will have to re-pair the wifi remote. When the roku is bouncing, start pressing anf holding the pairing button in the battery compartment, when stops bouncing, release for a bit and start pressing again until you get confirmation its paired. First thing it has you do is pick language.
Language choice never comes up. I did all the steps to pair at least 5 times. The language choice still doesn't appear.
How about Settings->System->Language? You should be able to translate what's shown now into those 3 words.
start by downloading the Google translate app. Select camera and walk up to your tv screen to see what menu items say in english
go ahead to that link site, setup account.
then install Roku Phone app and link with that code
find the word “idioma” change to english
Look up on your computer german word for language. Look thru settings and find the language
word in german and change to English, or the same for Spanish to find English. It worked for me, just
took some time, not unlike getting some customer service help that always takes time.
