Step by Step Guide
Step 1: Install the Signmitra app

Open the Amazon Appstore on your Fire TV Stick, search for Signmitra, and install the app. Launch it once installed.

Step 2: Enable Developer Options

From the home screen, go to Settings → My Fire TV (or Device) → About.

Select your Fire TV model name (e.g. “Fire TV Stick 4K Max”) and click it 7 times.

Note- When you see “No need, you are already a developer,” Developer Mode is enabled.

Go back to My Fire TV → Developer Options and turn ADB Debugging to ON.

Step 3: Find your Fire TV Stick IP address

Go to Settings → My Fire TV (or Device) → About → Network.
Note the IP address shown on screen (e.g. 192.168.10.38).

Step 4: Download ADB Platform Tools

Download Platform Tools from the Android developer website.

Choose the correct version for your operating system (Windows or macOS) and extract the files to an easy-to-find folder.

Step 5: Connect to Fire TV Stick and run ADB commands

Windows

Open File Explorer and navigate to the extracted platform-tools folder.
Right-click inside the folder and choose Open in Terminal.
On older Windows versions, hold Shift and right-click, then choose Open PowerShell window here.
Run the following command to start the ADB daemon:
adb devices
If successful, you will see the ADB daemon start.
Connect to your Fire TV Stick using its IP address (replace with your actual IP):
adb connect 192.168.10.38
On the Fire TV Stick, a prompt will appear asking to allow USB debugging. Check Always allow from this computer, then click Allow.
Verify the connection:
adb devices
You should see your device listed:
192.168.10.38:5555 device
Run the permission command (replace 192.168.10.38 with your Fire TV Stick IP address):


macOS:
Open Terminal and navigate to the extracted platform-tools folder:
cd ~/Desktop/platform-tools
Run the following command to start the ADB daemon:
./adb devices
If successful, you will see the ADB daemon start.
Connect to your Fire TV Stick using its IP address (replace with your actual IP):
./adb connect 192.168.10.38
On the Fire TV Stick, a prompt will appear asking to allow USB debugging. Check Always allow from this computer, then click Allow.
Verify the connection:
./adb devices
You should see your device listed:
192.168.10.38:5555 device
Run the permission command (replace 192.168.10.38 with your Fire TV Stick IP address):

Step 6: Launch Signmitra

Return to the Fire TV home screen and open the Signmitra app.
The permission error should now be gone, and Start at boot and auto-boot should work normally.
