How to Enable Unknown Apps on Firestick & Android TV Using Downloader (2026 Guide)
Installing IPTV players and third-party streaming apps on Firestick or Android TV requires enabling app installation from unknown sources. This allows your device to install APK files that are not available on the Amazon Appstore or Google Play Store.
In this updated 2026 guide, you’ll learn how to:
- Install the Downloader app on Firestick
- Unlock hidden Developer Options
- Enable unknown apps permissions safely
- Sideload IPTV APK files on Fire TV and Android TV

Sideloading refers to installing applications from external sources instead of the official app store. Firestick and Android TV both support sideloading, making it possible to install IPTV players, streaming tools, and APK files manually.
Unlike rooting or jailbreaking, sideloading is a standard Android-based feature supported by Fire TV devices.
⚠️ Important: Only install APK files from trusted websites and verified developers.
Downloader is a popular utility app for Fire TV and Android TV devices that allows users to download APK files directly using links or Downloader codes.
Features include:
- Built-in web browser
- Fast APK downloads
- Simple TV remote navigation
- Direct file installation support
How to Prepare Firestick & Android TV for APK Installation
The Downloader app is one of the easiest ways to install APK files on Firestick and Android TV devices. It allows users to download third-party applications directly using URLs or Downloader short codes.
Step 1: Install Downloader on Firestick
Since Firestick blocks direct APK downloads through most browsers, Downloader is the recommended method for installing third-party applications safely.
Downloader is available directly from the Amazon Appstore and only takes a few minutes to install.

From the Firestick home screen, go to Find and then select Search.

Step 2: Enable Unknown Apps & Developer Options
Amazon Fire TV devices block third-party APK installations by default. Before sideloading IPTV apps or media players, you must manually enable Developer Options and allow Downloader to install external apps.
