Install on Amazon FireTV Stick ​

This guide walks through installing the Lumicast Digital Signage Player on the Amazon FireTV Stick. It was written using the FireTV Stick 4K MAX.

Installation prerequisites ​

  • A physical display with HDMI input
  • Power
  • Wi-Fi

FireTV Stick setup ​

  1. Plug the FireTV Stick into the display and connect power.
  2. Follow the on-screen setup steps.

Install the Lumicast Digital Signage app ​

Go to the app store: Find (🔍) > Appstore > Search. Search for "Lumicast", scroll to the APPS AND GAMES category, select Lumicast Digital Signage Player and install.

Before keeping the FireTV running 24/7, disable the screensaver:

Settings > Display & Sounds > Screensaver > Start Time > Never

Open the Lumicast player again and connect the display to Lumicast.

Autostart Lumicast on device boot ​

You want Lumicast to launch automatically after a power cycle.

  1. Open the Lumicast menu (press M on a keyboard, or OK/Enter on the remote).
  2. Navigate to Launch on boot and enable it.
  3. Reboot via Settings > My FireTV > Restart.

In many cases the Amazon stick blocks this auto-start flow. If Lumicast doesn't come back on its own, continue below.

Grant permissions via ADB ​

You'll need Android platform-tools on your computer. Download from Android Studio command line tools and extract the ZIP.

On Windows ​

  1. Open the platform-tools folder in File Explorer.

  2. Right-click inside the folder (not on a file) and choose Open in Terminal (or Shift + Right-click > Open PowerShell window here).

  3. Start the ADB daemon:

    bash
    adb devices

    Expected output:

    * daemon not running; starting now at tcp:5037 *
* daemon started successfully *
List of devices attached

  4. Connect to your Fire TV (replace the IP with your device's IP):

    bash
    adb connect 192.168.10.38

  5. On the Fire TV, approve the Allow USB Debugging? prompt — check Always allow from this computer and press Allow.

  6. Verify the connection:

    bash
    adb devices

    Expected output:

    192.168.10.38:5555 device

  7. Grant overlay permission to the Lumicast player:

    bash
    adb -s 192.168.10.38:5555 shell cmd appops set lumicast.app SYSTEM_ALERT_WINDOW allow

  8. Launch the Lumicast player. The permission error is gone and auto-start works.

On macOS ​

  1. In Finder, locate the extracted platform-tools folder.

  2. Right-click it and choose New Terminal at Folder.

  3. Start the ADB daemon:

    bash
    ./adb devices

  4. Connect to your Fire TV (replace the IP):

    bash
    ./adb connect 192.168.10.38

  5. On the Fire TV, approve the debugging prompt — check Always allow from this computer and press Allow.

  6. Verify:

    bash
    ./adb devices

  7. Grant overlay permission:

    bash
    ./adb -s 192.168.10.38:5555 shell cmd appops set lumicast.app SYSTEM_ALERT_WINDOW allow

  8. Launch the Lumicast player. Overlay permission is now in place.
