Here we explain how to allow "Unknown Sources" on your FireTV device.
Since we will be sideloading apps like 6IPTV or SmartIPTV on FireStick, we need to enable “ Apps from Unknown Sources ” security option first in FireStick settings. Follow the steps below:
Step 1: You must be on the home screen of your FireTV Stick. From there, navigate up and select the “ Settings ” ( gear ) option.

Step 2: Go to My Fire TV option in Settings.

Step 3: Please select the " Info " option.

Step 4: You should now be presented with 4 options, with the top option being the FireTV Stick.

Step 5: Press the options button of your FireTV Stick about 7 times until the message " No need, you are already a developer " appears.

Step 6: Please go back to the " My Fire TV " options tab. The next option you access is the "Developer Options ".

Step 7: Now please activate the option “Apps from Unknown Sources” / “Apps from Unknown Sources”.
You only need to enable this if it is currently disabled .

Step 8: You will be prompted with a warning message that it is not safe. The message appears because activation can also install apps that cannot be found in the Amazon Store. Please activate the option. We only recommend user-friendly apps. So nothing to worry about.
Please click on “Activate / Switch on” now.

Once you have enabled Apps from Unknown Sources, you can start installing the apps on the Amazon FireTV Stick.
