The new Unifi STB does not require root to install apps from unknown source. You can just sideload those apps' APK file via USB flash drive...but, you need at least a file manager installed from Google Play Store to help in installing the APK. Use OI File Manager from OpenIntents available from Google Play Store (use this successfully from Unifi STB last time with WIFI dynamic IP setup.)
