Media player only — no content included

OTOO does NOT provide, host, or sell any channels, movies, or streams. It only plays the M3U or Xtream playlist you add yourself — you are responsible for the content you play.

Amazon Fire TV

Install OTOO on your Fire TV Stick

OTOO is not in the Amazon Appstore yet, so it is installed by hand with the free Downloader app. It takes about five minutes. Start by checking which device you have — not every Fire TV can do this.

First: which Fire TV do you have?

Amazon now sells two different kinds of Fire TV. The older ones run Fire OS and can install OTOO. The newest sticks run Vega OS, which cannot install apps from outside the Amazon Appstore at all — no setting, no workaround.

Not sure? Check on the device itself

On the Fire TV open Settings → My Fire TV → About. If the software version starts with a 1, you have Vega OS and cannot install OTOO this way. If it starts with 5, 6, 7, 8 or 14, you have Fire OS and the steps below will work.

Device Year System
Fire TV Stick 4K Plus 2025 Fire OS 8
Fire TV Stick HD (1st gen)Wi-Fi 5, squared corners, no "Fire TV" text on the stick. 2024 Fire OS 7
Fire TV Stick 4K Max (2nd gen) 2023 Fire OS 8
Fire TV Stick 4K (2nd gen) 2023 Fire OS 8
Fire TV Cube (3rd gen) 2022 Fire OS 7
Fire TV Stick 4K Max (1st gen) 2021 Fire OS 7
Fire TV Stick (3rd gen) & Fire TV Stick Lite 2020 Fire OS 7
Fire TV Cube (2nd gen) 2019 Fire OS 7
Fire TV Stick 4K (1st gen) 2018 Fire OS 6/7
Fire TV Cube (1st gen) 2018 Fire OS 6
Fire TV Stick (2nd gen)Old and slow, but OTOO installs — the app supports 32-bit devices. 2016 Fire OS 5
Fire TV smart TVs (Fire TV built-in / Fire TV Edition)The settings section has a different name on these — see step 1. 2017+ Fire OS 6–8

These all run Fire OS — OTOO installs on every one of them.

Cannot install OTOO this way Year System
Fire TV Stick HD (2nd gen)Shares its name with the 2024 model. This one has Wi-Fi 6, rounded corners and "Fire TV" printed on the stick. 2026 Vega OS
Fire TV Stick 4K SelectThe first Vega stick. Not to be confused with the 4K Plus of the same year, which is Fire OS. 2025 Vega OS

These run Vega OS, which is not Android and does not allow installing apps from outside the Amazon Appstore. Every Fire TV Stick Amazon releases from now on will be this kind. We are working on a version for them.

The five steps

Everything below happens on the Fire TV itself, using the remote. You do not need a computer or a phone.

The menu names below are written exactly as they appear on the device, in English. Fire TV offers its interface in only a handful of languages, so the names on your screen may not match the language of this page — look for these words as they are printed here.

  1. Show the hidden developer menu

    On recent Fire TV software this menu is hidden. Open Settings → My Fire TV → About, highlight the first line (your device name) and press the select button on the remote seven times. A short message confirms it, then press Back — the menu Developer options is now in the list.

    On older devices that menu is visible already — if you can see it, skip this step. On a Fire TV smart TV the section is called Device & Software instead of My Fire TV.

  2. Install the Downloader app

    From the Fire TV home screen, search for Downloader and install it from the Amazon Appstore. It is free. This is the app that will fetch OTOO for you.

  3. Allow Downloader to install apps

    Open Settings → My Fire TV → Developer options. Depending on how old your Fire TV software is, you will see one of these two things:

    Install unknown apps A list of apps. Find Downloader in the list and switch it on.
    Apps from Unknown Sources A single on/off switch. Turn it on.

  4. Open Downloader and type the address

    In the Downloader address box, enter exactly this and start the download:

    otoo.app/fire

    No “www”, no “https”. The download is about 66 MB, so give it a minute on a slow connection. When it finishes, confirm the install. You can delete the downloaded file afterwards when Downloader offers to.

  5. Open OTOO and add your playlist

    OTOO appears at the end of your app list on the Fire TV home screen — hold the Home button and choose Apps if you cannot see it. Open it and note the device code on the start screen, then add your own M3U or Xtream playlist to that code at otoo.app. Until you do, OTOO shows a small demo library of freely licensed films so you can try the interface.

If something goes wrong

The three problems people actually hit, and what they mean.

The developer menu is nowhere to be found
Amazon hides it on newer software. Open Settings → My Fire TV → About, press the select button seven times on the first line, then press Back. If pressing seven times does nothing at all and the software version starts with a 1, you have a Vega OS stick and it cannot install OTOO — see the table at the top of this page.
Downloader is not in the list of apps
Install Downloader first and open it once — apps only appear in that list after they have been installed. If it is still missing, restart the Fire TV and look again.
It warns about an unknown developer, or says the app was not installed
The unknown-developer warning is normal and unavoidable for any app not installed from the Amazon Appstore — it says nothing about the app itself. OTOO is properly signed. A failed install usually means the download was interrupted or storage is full: free some space, then run the address above in Downloader again.
