Let‘s get started!

What is Sideloading and How Does it Work?

Sideloading refers to installing apps on your Fire TV device directly, without going through the Amazon Appstore.

You first enable "unknown sources", which permits installing apps from outside the Appstore. Then, you can download an APK (Android application package) file containing the app code. Using a utility like Downloader, you can finally sideload the APK onto your device.

Once installed, sideloaded apps appear in your app library like any other app. You can open them, use account credentials, and access all content as normal.

Here are some key benefits unlocked by sideloading:

  • Install apps unavailable in the Appstore like YouTube, Facebook, Hulu, and over 50,000 more
  • Remove limitations of Appstore apps – for instance, sideload ad-free YouTube
  • Access unique apps developed specifically for Fire OS but not listed publicly
  • Use Android apps designed for phones/tablets on your Fire TV
  • Customize your Firestick with advanced tools for power users

According to Aptoide, there are over 2.2 million more apps available via sideloading compared to the paltry 5,000 in the Appstore. Sideloading vastly expands what you can do with your Firestick.

Next, let‘s look at how to get your device ready for sideloading.

Step-by-Step Guide to Enable Unknown Sources

Before you can install any sideloaded apps, you must first enable "unknown sources" on your Firestick. Here‘s how:

  1. From the Home screen, go to Settings.
  2. Select My Fire TV or Device (depends on model).
  3. Choose Developer Options.
  4. Turn on Apps from Unknown Sources or ADB Debugging (varies by device).
  5. Confirm the warning message by selecting Turn On.

You may be asked to enter your device passcode or Amazon account password before making changes.

Once unknown sources is enabled, your Firestick is ready to install sideloaded APKs. Let‘s look at how to do that using the popular Downloader app.

How to Use Downloader App for Easy Sideloading

Downloader provides the easiest way to find, download, and install APK files onto your device. Just follow these steps:

Install Downloader App

  1. From Home screen, search for "Downloader" and select app.
  2. Download and install Downloader.
  3. Grant requested permissions when prompted.

  2. Type URL of site hosting APK, such as
  3. Find and select the app APK link to download.

For example, to download Terrarium TV:

  1. In Downloader, type
  2. Search for Terrarium TV
  3. Click "Download APK" button

The APK will automatically begin downloading onto your device.

Install Downloaded APK

  1. After download completes, open Downloader.
  2. Select the "Install" button next to downloaded APK.
  3. Click "Done" after installation finishes.
  4. Choose "Delete" to remove the APK file after installing.

That‘s it! The app is now installed and ready to use. Repeat for any other APKs you want to sideload.

Alternative Methods for Sideloading Apps

While Downloader is the easiest way to sideload, here are a couple advanced options:

Using a File Explorer

You can use a file manager like ES File Explorer to find and install APKs:

  1. Install file explorer from Appstore
  2. Locate downloaded APK in storage
  3. Select APK and tap "Install"

This gives you more control over storage and apps. But Downloader simplifies the entire process.

Sideload from a Computer

For full customization, you can sideload APKs directly from a computer:

  1. Connect Firestick and computer to same WiFi network.
  2. Obtain your device IP address from Settings > Network.
  3. On computer, enter IP into file explorer, such as \\\
  4. Drag & drop APK file onto Firestick drive.
  5. Use Downloader or file manager to install APK.

While powerful, this method is time intensive compared to Downloader.

Sideloading Safety Tips and Troubleshooting

Sideloading is a safe process as long as you take precautions. Here are tips to avoid risks:

  • Only download APKs from official developer sites when possible.
  • Scan new APKs with antivirus software before installing.
  • Check app reviews and developer reputation. Avoid shady or unknown sources.
  • Stick to reputable app distributors like Aptoide TV, Apkmirror, Apkpure.
  • Don‘t install apps related to illegal streaming or copyrighted content.
  • Make regular backups in case you need to reset your device.

You may also encounter issues like apps not installing properly. Here are some common troubleshooting solutions:

App won‘t install: Enable unknown sources for that specific app under Settings > Developer Options.

App installed but crashes/doesn‘t open: The APK likely isn‘t compatible with your device firmware. Try a different APK version or re-download.

Apps suddenly missing: Reboot device to restore Appstore apps hidden by enabling unknown sources.

Cannot download APKs: Check internet connection and disable any VPN services temporarily.

For additional support, search for your specific problem online to find specialized help from other Firestick users.

Now let‘s answer some frequently asked questions about the legality and risks around sideloading.
