I just recently got a Xiaomi Mi Box in the living room and was thinking about grabbing a second one to put in my bedroom. However, I was digging through some drawers full of old tech and came across a Remix Mini that I bought about 3 years ago and pretty quickly forgot about.
Is there anyway I can remove Android Remix OS on the Remix Mini and replace it with Android TV? Remix OS just isn't really suitable for how I want to use it.
Check Freaktab to see if there is a custom ATV ROM for your box. If not, and your box is rooted, you can also gain most Android TV functionality, with the exception of certain things like casting...
Shoot me a msg if you have root and are interested in manually setting things up. I wrote a guide a while back.
Again, it's not perfect, but a good way to salvage old electronics.
