Is there a source link I can add to get the official Kodi Repository ?
The Zoomtak Andriod boxes comes with Helix 14.2 installed, but they are missing the Kodi Repository, only the Kodi PVR repository is installed.
This is strange on why they would do this as I have not seen any box manfacturer do this with an official Kodi build.

Best guess they are probably using a custom build of Kodi that creates compatibility issues with add-ons from the official repo so they have removed it.

My advice with be to compete remove their build and install the official build from the Play Store or sideload the official APK. Whether you can do this will depend on the box and it's firmware. Some of these boxes come with crappy restricted firmwares making this very difficult.
