Android OS has many functions and features not accessible to everyone. To access these functions, you will need to be rooted. This is also called super-user permissions.
iRoot was formerly vRoot. It allows users to root a device with their computers, and gives them super-user access to various functions that normally are not available. iRoot allows users to uninstall all bloatware and pre-installed apps.
Simply connect your device with the USB cable to the computer and then wait for it to be recognized by the program. Follow the instructions to complete the operation. This program may not be compatible with the most recent Android versions.
