You don’t understand…
The Homatics R 4k Plus box, which was the ideal box for reading Dolby Vision files with FEL under Android TV 12, has been updated to Android TV 14 for many people, which means there is a new Android Kernel…
So the version of CoreElec NG that worked well on the box with Android TV 12 no longer works on Android TV 14!
We will have to use the NO version of CoreElec to make it work on the box with Android TV 14. And this NO version does not support DV files with FEL (and it never will according to what is said here).
It is possible to revert to Android TV 12 on the box, but it’s not available to everyone and not without risk…
And it is not supported by the brand because it requires the use of pirated firmware.
