Here's a complete guide on how to use Screen Stream Mirroring without having root access.
From your computer download our startup tool.
Choose the archive corresponding to the operating system of your computer (Windows, Linux, or MacOSX) and UNZIP entire content.
Check that the "USB debugging" option is enabled on your Android device.
Method 1
Use the "USB debugging option" menu/shortcut from the application, find and enable USB debugging option.
Method 2
On devices running Android 4.0 and newer, you can find the option under Settings > Developer options.
Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options, find and enable USB debugging option.
Connect your device to your computer with USB cable and make sure your device is recognized.
For Windows users, now that USB debugging is enabled, if not already installed the system will need ADB drivers for your device. Read bellow or go to FAQ if you need help about ADB drivers.
Start Screen Stream Mirroring application on your Android device.
From your computer run the program "startService".
Authorize your computer if a confirmation dialog appears on your Android device.
If the application restarts and shows a "Mirroring available at..." message, then you are ready and it should work with your unrooted device.
Please note that if you restart your device you will have to run again the startup program to use the application. If you don't restart your device Screen Stream Mirroring will continue to work normally.
First
Check that you authorized your computer if a confirmation dialog appeared on your Android device.
Second
For Windows, check you have proper Windows ADB drivers.
