Hello, I sideloaded Nougat beta on to my US MiBox (to fix stuttering on Netflix) and now I can't upgrade to Oreo. Tried factory restarting but it kept me on 7.0. I found a downgrade but it seems like it only works on the international version :(
tl;dr MiBox is stuck on Nougat beta, want to upgrade to Oreo
The US version of the Mi Box is the international version.
You have two options:
Though to be clear, there is no public release of Oreo on the Mi Box , simply a closed beta for those who are part of the original (pre-release) Mi Box beta program. If you're seeing updates, it's likely because it's trying (and failing) to install a more recent MM build.
