Can I make that be more like what Google wants Android TV to be? Launcher, Android O, voice search, etc...? Probably everything EXCEPT for the important stuff like proper DRM and security support. That means no Netflix, Chromecast or other streaming vehicles that will soon require DRM. Your best bet is buy Xiaomi Mibox and get everything legit in same package https://appsync.biz/abcya/ https://appsync.biz/adam4adam/] https://appsync.biz/pof/
This thread is about the Zidoo X20. If you want to discuss Xiaomi boxes, i am sure they have their own forum for this but here it’s off topic.
