While the desire to restore functionality is understandable, it is crucial to acknowledge the dangers of this pursuit. Searching for "Smart TV YouTube 6.17.391 download latest" leads users away from official app stores into the wild west of APK mirror sites. The risks include:

LG does not allow native APK installation. However, advanced users can use "Dev Mode."

Step 1: Go to LG Content Store and download "Developer Mode" app. Step 2: Register your TV as a dev device (requires a simple sign-up). Step 3: Use a laptop on the same WiFi to push the YouTube IPK file (converted from 6.17.391) over SSH. Step 4: Restart the TV. Warning: This voids the warranty if misused.

Even after installing 6.17.391, the Google Play Store will detect an update available. Do not update it, or it will revert to the new version. You may need to turn off "Auto-update apps" in the Play Store settings.

If the Play Store is not offering the update yet, you can manually install the YouTube 6.17 391 APK. This is legal because YouTube is a free app, but you must be careful where you download the file.

Smart YouTube TV version 6.17.391 is a legacy third-party open-source client designed specifically for older smart TVs and Android TV boxes that no longer receive official updates. While it is no longer the "latest" version of the app—having been succeeded by SmartTube (formerly SmartTubeNext)—it remains a popular "fix" for users with aging hardware. Key Features & Performance

Legacy Hardware Support: This specific version (6.17.391) is highly valued because it supports Android versions as old as 4.0 (Ice Cream Sandwich), allowing many "frozen" smart TVs to access YouTube again.

Resolution & Playback: Supports up to 4K resolution and is optimized for TV remotes, unlike the standard mobile YouTube app.

Google Services Independence: It does not require Google Play Services to function, making it ideal for generic Android boxes or devices with limited software ecosystems.

No-Ads & Customization: Historically, this client provided built-in ad-blocking and background playback features that are not available in the official YouTube for Android TV app. Version Comparison (April 2026)
