Guide to Installing Android OS on Smart TV

Here is a quick guide to installing Android OC on your Smart TV.

Prepare ADT-3 Developer Kit for Android TV OS.

ADT-3 Developer Kit works essentially as an Android smart TV. Therefore, you need access to its Developer Options to unlock the “Bootloader” and enable “USB Debugging.”

Here is how you prepare the ADT-3 Dev Kit for Android TV OS:

Step 1: Navigate around your Android smart TV home screen using the Askey remote and click the “Settings cog” at the top right of the screen.

Step 2: From the list that shows up, click “Device Preferences” > “About.”

Step 3: Scroll down to the “Android TV OS Build” option. Click on it 7-8 times using the remote, and you will see a prompt reading, “You are now a developer.”

Step 4: Go back to the “Device Preferences” screen and scroll down to the “Developer Options” menu.

Step 5: Scroll down to the option named “OEM Unlocking.” Toggle it ON and then accept any warnings that show up.

Step 6: Scroll further down to “Debugging” > “USB Debugging.” Toggle it on and accept any warnings that pop up on your smart TV screen.

Your ADT-3 Dev Kit is now ready for the Android OS installation.

Install Android OS on your Android Smart TV

This entails the following steps:

Step 1: Connect the ADT-3 device to your laptop’s port using its USB output and open the “Android Flash Tool” in the Google Chrome browser.

Step 2: Select the “Allow ADB Access” button in the prompt that shows up. Click the down arrow from the next menu to choose your device.

Step 3: From the prompt that shows up tap “Allow” to complete the connection. You can tap the “Always Allow” option to approve any future connections. Once the connection is secured, tap the “Add Device” option.

Step 4: Select “ADT-3 – Paired” from the pop-up menu and tap the “Connect” button. Tap on your device name once, and a list of the available Android TV OS builds will open up. Click on any of the available Android TV OS to select it.

Step 5: Click on the “Install build” button to begin the installation process. While you can see the “edit button” to edit a few settings, it is recommended that you work with the default settings.

Step 6: A list of your chosen settings and warnings will show up. Read through the details and tap “Confirm” to start the installation. Click the “I Accept” button to accept the License terms  on the next screen.

Your ADT-3 device will go into bootloader mode when the installation process begins. Be sure NOT to unplug your device from the power source or the USB port.

Step 7: Your ADT-3 tool will ask permission to unlock the bootloader completely. Read through the warnings and tap the “Start” button. DO NOT unplug any device or disconnect from the internet when Android TV OS begins downloading. This will be followed by the Android TV OS flashing and rebooting process.

Step 8: The last step will request you to re-lock the bootloader to complete the installation process. Therefore, tap the “Start” and click “Done” to lock the bootloader and finish the installation process.

You are now done! The ADT-3 Dev Kit will now reboot, and an Android TV OS animation will appear, followed by a one-time setup that you will be required to complete to get to the home screen. You can now unplug the ADT-3 Dev Kit from your laptop or PC.


Although it may seem a complicated process at first, installing the Android TV OS on your smart TV is actually straightforward. All that’s needed is a Google Chrome web browser with a stable internet connection, some USB drivers, and ADT-3 Developer Kit to get the popular Android TV OS installed on your smart TV.
