root a phone It is the most effective method to have full control over our device and modify it to make it work exactly the way we want. However, on a rooted smartphone we may find that some applications and functions do not respond. For this reason, in many cases, it is necessary to undo the work and unroot android
There are some ways to hide root, but it is not always an effective solution. In addition, if what we want to do is update the system, sell the mobile or take it to be repaired, it will be essential to eliminate the root completely, without leaving the slightest trace of the operation.
What is a root and what is it for?
Let's recap. Said very superficially, there are two ways to handle Android: as a simple user or as a Super user, a level that is locked by default so that only the manufacturer can decide to what extent it allows its users to make changes to the system.
The truth is that Android gives its users a lot of freedom (we can install any kind of application on their devices), but when we root we remove all restrictions and, thanks to a specific application, we can become superusers.
What are the advantages of doing this? This operation will allow us to install versions of Android not authorized by the manufacturer, uninstall "armored" applications, install others that may affect the performance of the processor or the battery, and achieve a greater degree of customization.
There are also some risks. For example, in case of having problems, the manufacturer can ignore the guarantee, since we have broken the rules.
On the other hand, the reality is that Android is increasingly optimized, so rooting a phone, as many users used to do before, It makes less and less sense.
Methods to remove root on Android
In any case, there is always the possibility of returning to the previous state, if that is what we need. Here's how to do it:
From the root's own management application
Almost all root management applications have their own removal function. To put it into operation, you only have to access its settings menu and select the option, which is usually called uninstall root, remove root o unroot, depending on each application. Then we will have to restart the system manually.
There are some applications that force us to connect the mobile to a computer to remove the root through it, but despite this, the process is not complicated at all.
With the manual method
If we find that the root management application does not have an unroot or similar function, or if it does not work after having tried it, we will have to resort to the manual method.
For this purpose there are some applications specialized in “unrooting” devices which work really well. One of the best is Universal Unroot Impactor. And it's also free:
However, the safest and most effective is to delete the files on our own. For this we need the help of a file manager with root permission. There are several that can guide us well in this task, such as X-Plore File Manager: Here is your link to the Google Play Store:
The "mission" consists of locate and delete all root access files. They are not always located in the same folders and their names may vary depending on the root management application that we have used. Basically, they are the following files:
/system/bin/su
/ system / xbin / su
/system/app/superuser.apk
reinstall firmware
Our third and last option to unroot Android is also the most logical: reinstall factory software. What happens is that the way to do it is different in each manufacturer. Of course, they all have something in common: it will be necessary download the official firmware and flash it on the device. To do this, we will have to connect our mobile or tablet by cable to our computer.
