chromecast built in wont work as our devices dont have widevine level 1, thi cannot be changed, look for clock patches maybe help, and try taking libbt-vendor.so from working rom and copy acrossThank you @enerdude for your help. Do you have another advice?.
I tried this but again brick my box after 7% with the USB burning tool. I revived again with the firmware [atvXerience S905W_V2H_FINAL] but I don't like it because not working Clock, Chromecast built-in neither Bluetooth . BTW the Bluetooth work only with this firmware [AndroidTV_7_S905W_Bluetooth_Tue_Minh_20190320.zip a vietnamese].
I'll really appreciate if @aidanmacgregor can give us some light about it.
