How to Install NetMirror on Firestick (2026 Step-by-Step Guide)
NetMirror is a free streaming app that lets you watch movies and TV shows on Android-based devices. Because the Amazon Fire TV Stick runs a version of Android, you can install NetMirror on it too, even though it is not available in the Amazon Appstore.
Firestick owners like NetMirror because it turns a regular TV into a big-screen streaming setup. You get the same app experience you would have on a phone, just on a much bigger display, and you control everything with the Fire TV remote.
The process is called sideloading. It sounds technical, but it really just means installing an app file (called an APK) from outside the Appstore. This guide walks you through it in about ten minutes, step by step, with no rooting or complicated tools required. If you have ever installed the NetMirror app on an Android phone, the Firestick version works in a very similar way.
What You Need Before You Start
Make sure you have the following ready. You probably have most of it already:
- An Amazon Fire TV Stick (any model, 4K, 4K Max, Lite, or older)
- A TV with an HDMI port (where your Firestick is plugged in)
- A stable Wi-Fi connection
- The Downloader app (free, from the Amazon Appstore)
- About 5 to 10 minutes of time
How to Install NetMirror on Firestick
Follow these four steps in order. Do not skip Step 1, without it, your Firestick will block the installation.
Step 1, Enable Apps from Unknown Sources and ADB Debugging
First, you need to give your Firestick permission to install apps from outside the Amazon Appstore. From the Firestick home screen, go to Settings > My Fire TV > Developer Options.
If you do not see Developer Options in that menu, it may be hidden on your Fire OS version. Go to Settings > My Fire TV > About, select your device name, and press the select button on your remote 7 times. A message will confirm that developer mode is now on. Go back one screen and Developer Options should appear.
Inside Developer Options, turn on Apps from Unknown Sources (on some versions this is called Install Unknown Apps). Confirm when the Firestick warns you. Also turn on ADB Debugging. This is not always required, but it helps the installation go smoothly and avoids some common permission errors.
Step 2, Install the Downloader App from the Amazon Appstore
Downloader is a free, trusted app made for exactly this purpose: downloading files on Fire TV. From the home screen, go to Find > Search, type “Downloader” (it has an orange download-arrow icon), and select it from the results. Click Download or Get, then wait for it to install.
Open Downloader once. On the first launch it may ask for permission to access your files, accept this, since it needs to save the APK file to your device.
Step 3, Download the NetMirror APK with Downloader
Now open the Downloader app. You will see a URL field on the home tab. Enter the direct download link for the NetMirror APK, you can copy it from our NetMirror download page on your phone or computer first, then press Go.
Downloader will fetch the file and show a download progress bar. Wait until the download finishes completely. A slow connection can make this take a couple of minutes, so be patient and do not close the app.
Step 4, Install the APK and Open NetMirror
When the download completes, Downloader will automatically show an installation prompt. Click Install. If the install button is greyed out, go back to Step 1 and make sure Unknown Sources is turned on, then try again.
After installation, click Done (not Open, for now). Downloader will offer to delete the APK file to save space, you can accept this, since the app is already installed. Then press the Home button on your remote.
To find NetMirror, go to Settings > Applications > Manage Installed Applications and look for it in the list. Sideloaded apps sometimes do not appear in the recent apps row on the home screen. To add it there, highlight the app, press the menu button on your remote, and select Move to front so it stays easy to reach.
Tips for a Better NetMirror Experience on TV
NetMirror was designed for touch screens, so using it with a TV remote takes a little getting used to. These tips make it much easier:
- Install Mouse Toggle for Fire TV. This free app adds a mouse cursor you control with your remote, which makes tapping buttons and scrolling inside NetMirror far easier. You can find it in the Amazon Appstore.
- Keep the app updated. New releases fix bugs and add improvements. Check the latest version page now and then and reinstall when a newer build is available.
- Use a good connection. Streaming on a big TV uses more data than on a phone. A strong Wi-Fi signal, or an Ethernet adapter for your Firestick, gives smoother playback.
- Clear the cache occasionally. If the app ever feels slow, go to Settings > Applications > Manage Installed Applications, select NetMirror, and choose Clear cache. This does not delete your settings or data.
Troubleshooting: App Not Appearing After Install
If NetMirror does not show up after you installed it, do not worry, this is a common issue with a simple cause. Go back to Settings > My Fire TV > Developer Options and confirm that Apps from Unknown Sources is still turned on. Software updates sometimes switch this setting off.
Next, check Settings > Applications > Manage Installed Applications. If NetMirror is listed there, it installed correctly and is just hidden from the home screen, use the “Move to front” trick described in Step 4. If it is not listed, restart your Firestick (unplug it for 10 seconds, then plug it back in) and repeat Step 3.
