Updated manualy with update_zip method and it works. Even less lag after standby and I can finally turn of CEC on Mi Box S 4K.
Otherwise with CEC on standby problem was solved on old release, but sound would go crazy. For example, turning down volume in MiBox would also turn down volume on my receiver. And by this it got out of sync very quickly. Finally its completely fine.
Thanks.
ok thanks
What about the original mi box will it get android 9 update 🥺
Everyone please be careful when updating. We all now far to well from the Android 8 Update how unstable new Mi Box Builds can be, there could be a reason why Xiaomi isn't really pushing it out yet.
