1. Install the Downloader app
On the Firestick home screen, go to Find and type "Downloader". Install the app with the orange icon from the Amazon Appstore. You use it to fetch the player app, because most IPTV players are not in the Appstore itself.
2. Allow the installation
Open Settings, choose My Fire TV and then Developer options. Under "Install unknown apps", switch Downloader on. If you do not see the developer options, go to My Fire TV, About, and press the name of your device seven times.
3. Download the player app
Open Downloader and enter the link our support sends you for the player that suits you, for example IPTV Smarters or TiviMate. Choose Install when the download finishes, then delete the installer file to keep space free.
4. Log in and watch
Start the player app, choose to log in with Xtream Codes and enter the server name, username and password you received after ordering. The channel list and TV guide take a minute or two to load the first time. Connect the Firestick to 5 GHz wifi if you can, or use an ethernet adapter for the most stable picture.
