There are many advantages to an unlocked root Android smartphone, but also some disadvantages. The main advantage in unlocking Android, especially in unlocking the bootloader, is that of being able to install a custom ROM such as Lineage OS or Miui, of those that can make an old smartphone return new and that add functions absent on the normal Android.
At the same time, however, root Android is an operation that opens the system to any type of vulnerability and allows apps authorized by the permission manager (usually called SuperSU), to function as malware, send personal data to the external or spy on passwords and private data.
It is therefore a good idea, after unlocking the bootloader of the device, rooted it and installing a new version of Android or an update, to relock Android with the reverse procedure of Unroot which is really simple.
There are two easiest ways to reset root permissions and remove unlocking .
1) Using the SuperSU app
SuperSU is the application that manages access with other Superuser rights (the system administrator).
This application, which must always be installed after a root, also includes the possibility of "complete unroot".
Then open SuperSU and go to the Settings tab.
Scroll down until you find the full Unroot option.
At this point you can read the warning and press Continue to clean up the root permissions and relock the Superuser user on Android.
Restart the smartphone or tablet that will work without problems, except for apps that required Root permissions, visible from SuperSU to the app tab.
2) Using the KingoRoot or NExus Root Toolkit program
KingoRoot and Nexus Root Toolkit are two of the best programs with which you can Root any Android device in a super easy way, with a click.
Similarly, you can also remove the root.
Then download Kingoroot for Windows PC, connect the Android smartphone or tablet to the computer with the USB cable and make sure that the USB Debug option is enabled in the developer settings.
If the connected one is a Rooted device, Kingoroot will immediately show the button to remove the root, which is just a click away.
Through this program you can get and remove the root of Android with a click as many times as you want, without ruining anything and without problems, on the supported devices (almost all).
