Sideload Lion-OTT-IPTV on Firestick (Step-by-Step Guide)
Streaming has evolved rapidly, and devices like the Amazon Fire TV Stick have made it easier than ever to access a wide range of content. However, not every app is available in the Amazon Appstore, which is why many users choose to install Lion OTT IPTV on Firestick through sideloading.
In this step-by-step guide, you’ll learn how to install Lion OTT IPTV on Firestick quickly and easily, even if you’re new to the process. We’ll also cover setup tips, troubleshooting solutions, and best practices to help you enjoy a smooth streaming experience.

What is Sideloading on Firestick?
Sideloading is the process of installing applications from outside the official Amazon Appstore. Since Amazon restricts certain apps, sideloading allows you to manually install APK files.
This is especially useful for IPTV apps like Lion-OTT-IPTV, which often require manual installation.
Is Sideloading Safe?
Sideloading itself is safe—but it depends on where you download your APK file.
To stay safe:
- Only download APKs from trusted sources
- Avoid modified or “cracked” versions
- Keep your device updated
- Use a VPN if privacy is a concern
Requirements Before You Start
Before installing Lion-OTT-IPTV, make sure you have:
- A Firestick device connected to your TV
- Stable internet connection
- IPTV subscription credentials (M3U or Xtream Codes)
- The Downloader app
Step 1: Enable Developer Options
By default, Firestick blocks third-party apps. You’ll need to enable installation permissions.
Steps:
- Go to Settings
- Select My Fire TV
- Click About
- Select your Fire TV device name repeatedly (about 7 times)
- You’ll see: “You are now a developer”
- Go back and open Developer Options
- Turn ON:
- ADB Debugging
- Apps from Unknown Sources
This step is essential—without it, sideloading won’t work.
Step 2: Install Downloader App
The Downloader app is the easiest way to install APK files on Firestick.
Steps:
- Go to the Firestick home screen

The app is now installed on your Firestick.
Step 5: Delete APK File (Recommended)
