Picked one of these up when I was in China but it turns out there's no option to switch the Ui to English! Any thoughts on what I could do with it? I'm happy to flash it to stock Android if possible but I'm not sure how to go about it, there isn't much info out there on this device.
That is not an official AndroidTV tv box (nexus player, shield, Sony smart tv, and Razer ForgeTV) You are not likely to find anyone to help here.
I recommend trying freaktab.com and XDA developer forums.
