That is probably a question to ask google for details…
Basically…
* Enable `allow untrusted Apps` somewhere in the TV settings (Security & Restrictions I think)
* Download an app that can read the USB stick (I use X-plore File Manager)
* Download the correct 8.11 apk from the Android TV release Thread (I use the armv7 for my sony)
* Copythe file to a USB Stick
* Uninstall the current Version on your TV
* Insert USB Stick into TV,
* Use X-plore File Manager to Install Version from USB stick
* Turn off Auto Update Apps in TV
But it appears they have pulled 8.12.2 and are working on a fix ASAP
same issue here. Used to direct play all x265 files to my Google TV (new chromecast). Since server update 1.21.2.3943 it either won’t play, or play extremely choppy with static in the sound.
