Impactor Universal Unroot

Impactor Unroot is the ultimate-generation unroot tool, created for your Android device.
This software allows the user to perform a stable, complete and fast unroot. It will analyze and detect which parts of your operative system have been changed from the stock version and what should be fixed, by removing root access, busybox, extra unix binaries, startup daemons, and other root-managing utilities.
Impactor also offers a data wiping feature, for some old rooted devices having trouble wiping data from the built-in settings app.

Main features:
• Unroot (Permanent elimination of root access)
• Erase (Permanent elimination of user data)
• Full Reset (Unroot and userdata elimination)
• Rebooter (Advanced restart menu)

Warning: even though this app is very well tested and has successfully unrooted thousands of devices, use this software at your own risk.

Impactor is open source and the code is available at https://github.com/cioccarellia/impactor
