Smart Youtube Tv 617 740 |top| May 2026

⚠️ Important Safety Warning

Version 6.1.7.40 is an older version. Smart YouTube TV is developed by independent developers (first by Yuriy L., and later forks by others). Because it is not on the official Google Play Store, you must be careful when downloading APK files.

  • Recommendation: Always try the latest version first (currently in the v7.x or v8.x range), as it fixes bugs and supports newer YouTube features.
  • Why use 6.1.7.40? Users typically seek this specific older version because it runs smoother on older hardware (older TVs or boxes with limited RAM) or because newer versions were experiencing buffering issues on their specific device.

User Setting Toggles (in 740 Settings menu):

  • [x] Enable Chapter Badges
  • [x] Show High-Res Preview Thumbnails
  • [ ] Auto-Skip Silence (Smart Jump)
  • [ ] Voice Seek Assistant

7. Recommendation

Do not use version 6.17.740 or 6.17.617 — they are obsolete.
Instead, install the latest SmartTube (current active project) from its official GitHub:
https://github.com/yuliskov/SmartTube

The modern version has better performance, more features, and works with current YouTube APIs.

What If The Error Isn't An Error? (Search Intent Clarification)

It is worth noting that the keyword "smart youtube tv 617 740" is sometimes used incorrectly. If you typed this looking for a specific model number—for example, a Samsung TV model code ending in 617 or 740—please double-check your sticker. No major Smart TV manufacturer uses "617 740" as a model number. smart youtube tv 617 740

Alternatively, if you saw this string in a YouTube video title or description, it may be a timestamp (6:17 and 7:40) or a manual activation code for a third-party YouTube client (like SmartTubeNext for Firestick). In that case, treat it as a referral code, not an error.

4. Comparison with Modern Versions

Current active version of SmartTube (successor) is v20+ (as of 2026).
Version 6.17.740 is very outdated and may not work properly because YouTube’s API changes frequently.

| Aspect | v6.17.740 | Modern SmartTube (v20+) | |--------|------------|--------------------------| | YouTube API compatibility | Broken (likely fails to play many videos) | Fully compatible | | SponsorBlock | Basic | Advanced, with voting | | Return YouTube Dislike | No | Yes | | DeArrow (clickbait titles) | No | Yes | | HDR / AV1 support | No | Yes | | Android TV / Fire OS | Works on old OS | Works up to latest OS | ⚠️ Important Safety Warning Version 6

Do not install 6.17.740 today — it will probably show “error 400” or “video unavailable” on most content.

What is Smart YouTube TV?

Smart YouTube TV is an unofficial, third-party application designed for smart TVs (especially LG webOS and Samsung Tizen models) that cannot run the official YouTube app due to outdated firmware or regional restrictions. It acts as an alternative client to watch YouTube without ads and with additional features like background playback.

5. Security and Legality Notes

  • Not on Google Play Store — must sideload from GitHub or third-party sources.
  • Open-source — code can be audited (no known malware in official builds, but fake sites exist).
  • Legal status — Does not violate DMCA (no decryption of DRM), but it violates YouTube’s Terms of Service (ad blocking). Users have reported no legal action against individuals.
  • Risk — Older versions like 617/740 may have unpatched security issues.

The New Feature (For v740):

A redesigned seek bar that combines AI chapter detection with visual timeline previews. User Setting Toggles (in 740 Settings menu):

Key Capabilities:

  1. Chapter Badges on Timeline: When a video has chapters (from creator or auto-detected), small labeled markers appear directly on the seek bar.
  2. Frame-Accurate Preview Window: As you scrub, a large, high-resolution preview image appears above your thumb (configurable size), matching v617's performance but with 60fps smoothness.
  3. "Smart Jump" Button: A single button that skips over "dead air" (silence, long intros, static scenes) based on audio waveform analysis.
  4. Voice Seek: Hold the "OK" button and say "go to 12 minutes 30 seconds" or "jump to the review section".

If you wanted code to create a custom feature branch:

# Simulate branching from v617 to create v740 feature
git checkout smarttube-v617
git checkout -b feature/740-voice-navigation
# Add new voice command handler
echo "class VoiceSeekEngine  fun parseCommand(\"go to 10:30\") = 630000 " > VoiceSeek.kt
git commit -m "Feature: Voice seek (build 740)"
