Got this box for my parents to watch Netflix. Netflix needed an update that wouldnt work on the old version of android. So I gotta update android and dont know how.
I tried looking it up and I'm lost. Also looks like the newest firmware I can find is from 2017 which I think it already has.
Is this android box too old to update?
That's kind of outside the scope of this sub. We specifically discuss boxes that run Android TV (Google's official TV-focused Android distribution) here, and your device doesn't seem to be one of those. You might try /r/androidtvboxes or /r/androidbox for people that might be more knowledgeable.
Generally, I (and most people here) recommend against non-Android TV boxes, specifically because of the type of problem you're having here. They're generally hacked-together, buggy, have issues with common apps, and come with little to no post-sale support. You're extremely unlikely to get a new official firmware for this thing.
