So I am using a Smart TV box (ACT4K1007 from Skyworth) provided by my ISP. Its using certified Android TV. In last OS update they included Prime Video but an old version of the app (4.14.2). I can see the latest version in playstore on the box and an update option but when I try to update it, the installation fails with an error without much detail.

I then tried to download APK and install separately, then I got to know that the version installed along with OS update is placed in system core location hence unable to update it.

I am able to update other pre-installed apps(for ex Netflix) which show up under system apps but not the ones which show up as System Core apps.

I tried to uninstall using ADB but it doesnt delete the package without root and cant install newer version without that.

I am tryi g to find a way to either uninstall/update the existing package (but unable to find a way to root my device) or may be install a different version by using app clone etc. But couldnt make App Cloner work on Android TV.

Any suggestions how do I go about this? Any way to update the app under system core or any app cloner/dual app APK which works for Android TV?

Appreciate any help/responses.
