Fire TV Stick 4K Select — Jellyfin Not Supported / Sideload Blocked - ca2ju - 2025-11-23 Hi everyone, I want to report a compatibility issue that affects the new Amazon Fire TV Stick 4K Select (2024/2025). This device cannot run Jellyfin OR any sideloaded Android media apps, and they are also blocked in the Amazon Appstore. ❗ Symptoms confirmed Jellyfin shows: “Not compatible with your device” Downloader app is missing from Amazon Appstore Developer Options do not appear Apps from Unknown Sources is removed/hidden APK sideloading is blocked or fails silently This affects more than just Jellyfin — multiple streaming apps outside Amazon’s whitelist fail to install. 🔍 Likely cause Community findings indicate that Fire OS 1.1 (on the 4K Select) is not full Android anymore, but a restricted fork (often called Vega OS). It seems Amazon is applying: Stricter DRM/certification requirements Blocking of unapproved media apps Major sideloading restrictions Multiple users report this is part of a new crackdown by Amazon. 📡 Sources / community reports https://www.reddit.com/r/fireTV/comments/1omjapk/amazon_to_start_blocking_sideloaded_piracy_apps https://www.reddit.com/r/fireTV/comments/1onr28w/firestick_4k_select https://www.reddit.com/r/Stremio/comments/1p1m0em/new_firestick_os_doesnt_allow_for_sideloading 📌 Tested devices Device ResultFire TV Stick 4K Select (Fire OS 1.1) ❌ Not compatible Older Fire TV Stick 4K ✔ Works normally Region tested: Canada Server connections: Local + Remote both tested ✔ Temporary workaround Use Jellyfin via browser: Silk Browser → http://YOUR-SERVER-IP:8096 Works for playback, but missing the full Android TV UI. 🧭 Purpose of this thread Centralize info for Jellyfin users/devs Prevent others from buying unsupported hardware Track status if Amazon/Jellyfin adds compatibility later Share any successful sideload workaround if discovered 🙏 Request for updates If anyone has: Found a safe way to enable sideloading on Fire OS 1.1 Managed to run Jellyfin on the 4K Select Additional technical details about Vega OS Please share here so we can keep users informed. Thanks! This research and testing was done by me (a human), but the final text was written with AI assistance for clarity.
