The widespread use of the Android software platform, which runs a wide variety of devices - smartphones, tablet PCs, media players, etc., has led to the emergence of a huge number of applications that act as additional components that expand the functionality of the base OS.
Customization
All users who do not want to put up with some Android limitations imposed by device manufacturers turn to so-called customization - changing individual components of the operating system or expanding its capabilities with additional software packages.
Root
To perform serious manipulations with the software part of "Android" devices, the user will need superuser rights, as well as softwaresoftware that will allow you to manage root rights. One of the most popular superuser rights management solutions is the SuperSU app. It is worth noting that the utility perfectly performs the functionality assigned to it, but sometimes causes problems, the most common of which is the inability to update the SU binary file. Let's take a closer look at the application itself, and also try to figure it out: if the SU binary needs to be updated, what should I do in this case?
SuperSU program
The SuperSU application may appear in the user's device in automatic mode after the procedure for obtaining root rights. In addition, many custom firmware developers add already installed SuperSU to their solutions. If root rights are obtained, and there is no application to manage them, you can download and install SuperSU from the Google Play Store.
SuperSU Update
Regardless of how SuperSU was obtained and installed, after running it for the first time, in most cases, the user will receive a notification: "SU binary file needs to be updated." You can continue using the program quite often without updating. But still, it is advisable to follow the recommendations of the developers and follow the procedures, according to the prompts of the program, when the SU binary file needs to be updated. It is not difficult to perform the necessary actions, just click the "Update" button and select the appropriate update mode.
Emerging Issues
It would seem that when using the program in question to manage root rights, the user should not have any difficulties. What could be easier: when a SU binary file needs to be updated, update it in three easy steps and continue to enjoy all the benefits that comes with full access to the software side of the device.
But, as with many other apps, SuperSU's uninterrupted operation is unfortunately not guaranteed. Very often the following situation arises. After the user receives notifications from the program "SU binary requires updating", he tries to carry out the procedure in accordance with the prompts on the screen. The procedure is not always successful. Often, after rebooting the device, an error message is observed: "The SU binary file needs to be updated, the installation failed." What to do in this case?
Problem Solving
There are several ways to prevent the above error. Firstly, it must be initially taken into account that SuperSU must be installed on a clean system, not "littered" with other applications, especially in our case, those that manage superuser rights. Thus, if the SU binary file needs to be updated again and again, the installation fails and / or other errors occur, the solution may be to reset the device to the factory settings and repeat the procedure for rooting, as well as installing SuperSU again.
The second thing the user should remember is attentiveness and slowness during the update procedure. When you receive a notification that a SU binary needs to be updated, you should first try to update it normally. At the same time, one should not forget about the need for a Wi-Fi Internet connection on the device (connection via a mobile network is not suitable in this case). That is, after influencing the "Update" button in the SuperSU program window, select the "Normal" item. Then wait for the necessary data to be downloaded from the Global Network and the application itself to be manipulated, and after that, exit SuperSU and restart the device.
In the case when the previous methods did not bring results and the SU binary file that has already set its teeth on edge needs to be updated again, you will have to resort to the method of installing / reinstalling SuperSU through the modified "Android"-recovery. The most commonly used are TWRP or CWM recovery. To forget about problems with SuperSU forever, download the zip package containing the application files from the Web and install the resulting file through custom recovery. Such a cardinal method of resolving the issue helps in most cases.
If the above methods do not help to fix problems with SuperSU, the user needs to think about the compatibility of the firmware files and / or its components used by him with the "Android" device. HighlyInappropriate or corrupted installation files are often the cause of many problems, especially if they come from unreliable sources.
