It does work properly, I love it! I can cast my screen, stream photos/videos and apps to my tv.
These are the steps:
1. Download Mirrorenabler from OP link
2. It will prompt you to download SQlite installer. Download it and install within that app the required binary file
3. Open Mirrorenabler and switch it to 'enable'
4. Make sure you grant SU permission for both Mirrorenabler and SQlite installer
