What’s new in 617.391

Enable "Auto-Update" in your TV settings to never miss a performance boost. Method 2: Sideloading (For Android-based TVs)

Smart TVs have changed how we watch television, making it easy to stream video apps right from our living rooms. However, technology is not always perfect. Many Smart TV users frequently run into frustrating system glitches. One of the most common issues reported by viewers is the YouTube error code 617-391.

While watching a video, navigate to the Settings (gear icon) in the player.

If your TV says you are running the latest version but you are still experiencing issues, or if the update fails, try these steps:

Smart YouTube TV 6.17.391 (noarch) (Android 4.0+) - APKMirror

Supports up to 4K resolution, no root permission required, and a user interface optimized for TV screens. How to Download and Install

Neither SmartTube nor Smart YouTube TV is officially supported by YouTube or Google. While they offer enhanced features, users should be aware of the legal and security implications of using third-party clients.

For users who encounter compatibility issues, prefer a version not yet available in their region's store, or are seeking "extra quality" features such as ad-free playback and higher resolution support, sideloading APK files becomes an option. This method is particularly useful for Android TV boxes or smart TVs that lack Google Services.
