Remote only. No computer, no cables, no rooting. About five minutes.
TuneLoft isn't in the Amazon Appstore yet, so on Fire TV you install it yourself — a process called sideloading. It's a normal, supported Fire OS feature: you unlock the developer menu, turn on one setting, install Amazon's own Downloader app, and point it at our download link. Follow the eight steps below in order and you'll be watching in a few minutes.
What you need
A Fire TV Stick, Stick 4K, Stick Lite or Fire TV Cube on Wi-Fi.
The link to type
dl.tuneloft.tv/firetv
Current version
6.254.2
— the latest build, ahead of the stores.
On current Fire OS versions there is no “Developer options” entry until you reveal it. Don't go looking for it first — start here:
Settings → My Fire TV → About
Go back one level to My Fire TV: Developer options is now in the list.
Now that the menu exists, open it:
Settings → My Fire TV → Developer options
Press the microphone button and say “Downloader”, or search for it from the magnifying glass on the home row. It's the free orange app by AFTVnews, published in the Amazon Appstore. Install it, but don't open it yet.
This is the step most guides skip, and the one that makes installs fail silently. Downloader needs its own permission:
Settings → My Fire TV → Developer options → Install unknown apps
Find Downloader in the list and switch it on. If your Fire OS only offers the single global “Apps from Unknown Sources” toggle from step 2, there's nothing to do here — move on.
Open Downloader. On the Home tab there's a URL box — select it and type, exactly:
dl.tuneloft.tv/firetv
When the download finishes, Fire OS shows the TuneLoft install screen. Scroll down and choose Install, then Done (not Open — see the next step).
Downloader then offers to Delete the downloaded file. Say yes twice — the app is installed, the file is just taking up space on a device that hasn't got much.
Sideloaded apps don't appear on the Fire TV home row. Go to Apps (or Your Apps & Channels → See All), scroll to the bottom where TuneLoft sits, press the menu button (☰, three lines) on your remote and choose Move to Front. It'll be on your home row from now on.
Open TuneLoft and add a source: an M3U playlist URL, Xtream Codes credentials, a Plex server, a DLNA server on your network, or local files. TuneLoft ships with no content of its own — you bring your own sources, and your credentials stay on the device.
Typing a long URL with a TV remote is miserable. Two ways around it: install the Android Companion on your phone and pair it, or subscribe to TuneLoft Plus and activate the Fire Stick at tuneloft.tv/activate so your sources sync down on their own.
Sideloaded apps don't auto-update. To get a new version, open Downloader,
enter dl.tuneloft.tv/firetv
again and install over the top — your sources and settings are kept. Worth
doing every few weeks; this page always serves the newest build, which is
typically ahead of what the stores are carrying.
You have an older TuneLoft on the device that was signed with a different key. Uninstall it first (Settings → Applications → Manage Installed Applications → TuneLoft → Uninstall), then install again. Your sources will need to be re-added — one time only.
That's the normal state of a Fire TV out of the box — the menu doesn't exist until you unlock it. Do step 1: Settings → My Fire TV → About, highlight your device's name and press select seven times. If the presses don't register, make sure you're on the row naming the device itself and not on Storage or Network, and press at a steady pace rather than as fast as possible.
Downloader doesn't have permission to install. Go back to step 4 and switch Downloader on under Install unknown apps.
Re-type it carefully — dl.tuneloft.tv/firetv, lowercase,
no https://, no trailing slash. If it still
fails, check the Fire Stick is actually online (open any streaming app), and
note that some VPNs and DNS filters block the download.
Fire Sticks fill up fast. Uninstall an app you don't use, and make sure you deleted the APK file after installing (step 6).
Enable ADB debugging in the same Developer options menu, note the
Fire TV's IP under Settings → My Fire TV → About → Network,
then from your desktop run
adb connect <ip>:5555 followed by
adb install tuneloft-firetv.apk, using the APK
from the download page.
Is sideloading allowed? Yes. Fire OS ships the setting and Amazon documents it. TuneLoft is a media player — it plays sources you supply, and it comes with none of its own. You are responsible for the content you connect it to and for its legal compliance in your country.
We've submitted TuneLoft to the Amazon Appstore. Until it's listed, this guide is the way in — and even afterwards, the build on this site will keep landing before the store version does.
