Installation Guide

Step-by-Step: Install NetMirror on Firestick

Follow these 5 steps exactly. Each step includes detailed instructions for every Firestick model.

①

Step 1: Enable Apps from Unknown Sources

Since NetMirror isn't available on the Amazon App Store, you need to allow your Firestick to install apps from other sources. This is a standard Amazon setting — here's how:

For newer Firestick models (2022+):

Go to Settings (gear icon at the top of your home screen)
Select My Fire TV
Select Developer Options
Select Install Unknown Apps
Find Downloader and turn it ON

For older Firestick models:

Go to Settings → My Fire TV → Developer Options
Toggle Apps from Unknown Sources to ON
Confirm the warning prompt by selecting Turn On

Can't find Developer Options? Go to Settings → My Fire TV → About → click your device name 7 times rapidly. Developer Options will now appear in the My Fire TV menu.

②

Step 2: Install the Downloader App

Downloader is a free, trusted app that lets you download files (including APKs) directly to your Firestick. It's available right from the Amazon App Store:

From the Firestick home screen, select the magnifying glass (Search) icon
Type "Downloader"
Select the app with the orange icon by AFTVnews
Click Download or Get
Wait for installation to complete

💡 Alternative: You can also use your phone to send the Downloader app to your Firestick. Open the Amazon app on your phone, search for "Downloader", and select "Deliver to [your Firestick name]".

③

Step 3: Download NetMirror APK

Now use Downloader to get the NetMirror APK file:

Open the Downloader app
In the URL field, type the NetMirror download URL
Press Go
Wait for the download to complete (usually 30-60 seconds on WiFi)

Download NetMirror APK for Firestick

Version 6.0 • 28MB • Compatible with all Fire TV devices

Get Download Link

④

Step 4: Install and Launch NetMirror

After download completes, Downloader automatically prompts installation
Click Install
Wait for "App installed" message (10-20 seconds)
Click Open to launch NetMirror
When Downloader asks to delete the APK file, select Delete to save storage space

That's it! NetMirror is now installed on your Firestick. You can find it in your Apps list on the home screen.

⑤

Step 5: Install a VPN (Strongly Recommended)

Before you start streaming, install a VPN for privacy and security. NordVPN, ExpressVPN, and Surfshark all have native apps on the Amazon App Store — no sideloading required:

Search for "NordVPN" (or your preferred VPN) in the Amazon App Store
Download and install it
Sign in to your VPN account
Tap Quick Connect to connect to the nearest fast server
Now open NetMirror and enjoy private streaming!

💡 Remember: Always connect your VPN BEFORE opening NetMirror. Read our Best VPNs for Streaming comparison for detailed recommendations.

Tips to Get the Best Experience on Firestick

🔌

Use Ethernet

For the most stable 4K streaming, use an Amazon Ethernet Adapter ($15). WiFi can fluctuate, but Ethernet provides consistent speeds and eliminates buffering, especially on the older Firestick models.

🧹

Clear Cache Monthly

Firestick has limited storage. Clear NetMirror's cache monthly: Settings → Applications → Manage Installed Apps → NetMirror → Clear Cache. This frees up space without losing your watchlist.

📱

Use Phone as Remote

Download the Amazon Fire TV app on your phone. It provides a virtual keyboard (much faster for searching), voice search via Alexa, and touchpad navigation. Available on Android and iOS.

🖥️

Adjust Display Settings

Go to Settings → Display & Sounds → Display → Video Resolution. Set it to match your TV's capability (1080p or 4K). Also enable "Match Original Frame Rate" for smoother movie playback.

🔄

Keep Everything Updated

Update your Firestick OS: Settings → My Fire TV → About → Check for Updates. Also update NetMirror when new versions release — newer versions have better performance, fewer bugs, and security patches.

⚡

Restart Regularly

Firesticks don't fully shut down — they go to sleep. Restart weekly: Settings → My Fire TV → Restart. Or simply unplug the power for 30 seconds. This clears memory leaks and improves performance.
