This was a new-in-the-box MiBox and it's in Chinese from the very first start. I managed to get the language changed to English using a guide on Youtube, but the OS is clearly not AndroidTV and it's still got Chinese text and apps all over it. Is there a way to get this to the US version's OS? I tried the system update, but it says it's up to date.
Should I just return it?
Just return it. What you got wasn't the correct one.
