If you have decided to unroot your Android smartphone or tablet, for example, if you have decided to sell your device and want to remove the root access from it, there are quite a few methods for removing root access from your device. Here is a very simple method that anyone can easily follow.
In this tutorial, we are going to use SuperSU app (a must have app after rooting your device) for removing root access from your phone or tablet. The latest version of the app has such an option to remove root access.
1. Run the SuperSU app (if not installed, install it from Play Store).
2. Tap on the Settings tab on the top right corner, and then tap “Full Unroot” option. Confirm by taping ‘Continue’. It’ll take few minutes to complete the process.
3. Once this process is done, reboot your Android device.
4. Finally, uninstall SuperSU from your device. That’s it!
Please note that, some Android kernels automatically re-root at booting. By using the Root Checker app, you can confirm you no longer have root privileges on your device.
