A free program for Android, by Andrea Cioccarelli.
Impactor Universal Unroot is a powerful tool for your Android device. It is a program that will analyze your phone and detect which parts of the operating system are changed and what should be fixed. It can remove root access, busybox, extra Unix binaries, startup daemons, and other root-managing utilities.
The app is very well tested and has successfully unrooted thousands of devices. However, use this software at your own risk, as it is powerful and can cause issues.
If you are using a device with a root-only version of the operating system, you will need to download and install the appropriate drivers for your hardware.
