Part 7: FAQs – Smart TV YouTube 6.17.391

Q: Is version 6.17.391 the absolute latest?
A: No, Google periodically releases 6.18.x and 6.19.x, but many users revert to 6.17.391 because newer versions have introduced banner ads on the home screen or broken casting. Hence, 6.17.391 is considered the best stable version.

Q: Will I lose automatic updates if I sideload?
A: Yes. Sideloaded apps do not receive automatic Play Store updates. You will manually need to check for future stable versions. To re-enable auto-updates, uninstall the sideloaded version and reinstall from the Play Store (though you may get an inferior newer version).

Q: Does this work on Fire TV Stick 4K?
A: Absolutely. Fire OS is a fork of Android. Use the same APK. On Fire Stick, go to Settings > My Fire TV > Developer Options > Apps from Unknown Sources > Turn ON. Use the "Downloader" app same as Method 1.

A: No. An APK is a sandboxed application. It cannot modify system firmware. The worst-case scenario is the app fails to install or crashes, which is fixed by uninstalling.

The Anomaly of the Numbers

Let’s start with the obvious. The official YouTube app on Smart TVs (Samsung, LG, Android TV, Roku, etc.) does not use the version number 6.17.391.

For Android TV/Google TV: The current versions are in the 2.x or 3.x range, or the 1.x range for older models.
For Samsung Tizen: Version numbers are usually in the 1.x or 2.x range.
For LG webOS: Version numbers are entirely different.

The string 6.17.391 belongs to the mobile Android version of YouTube from roughly 2016 or 2017. Why would anyone be trying to install a 9-year-old mobile app onto a modern television? They wouldn’t. Unless they are trying to trick you.
