1. Amazon Fire TV Stick & Fire TV Cube (via Downloader)
Amazon does not list third-party Xtream players directly on the home screen, so the cleanest way to install your player on a Firestick is with the free Downloader by AFTVnews utility:
- From your Firestick home screen, select the Find / Search icon, type Downloader, and install the orange app published by AFTVnews.com (full developer documentation is available at aftvnews.com/downloader ↗ or on the Amazon Appstore ↗).
- Open Settings → My Fire TV → About, highlight your Fire TV Stick model name, and press the center select button on your remote 7 times until it confirms you are a developer.
- Press Back once, open Developer Options → Install Unknown Apps, and toggle Downloader to ON.
- Launch Downloader, enter the APK URL for your preferred player (such as IPTV Smarters or TiviMate), and click Install.
- Open the player, choose Login with Xtream Codes API, and enter the Server URL, Username, and Password from your Trex IPTV welcome email.
