With the beta firmware v6.2.5(_G) Zidoo updated Home Theater to version v4.0.53
I’ve created a modded APK for the Android 6/7.1 devices.
To get the Google Play Services you have to download Gappsinstaller from the Zidoo Application page.
Zidoo introduced a new system library libzidoomusic2.so with Music Player v6.9.3. I’ve copied libzidoomusic.so and libzidoomusic2.so from firmware Z9X v6.0.60 to my Z9S and it didn’t boot anymore. I’ve had to recover it.
