The binary SU file needs updating: what to do?

The wide distribution of the Android software platform, under the control of which a large number of various devices - smartphones, tablets, media players, etc., operates, has led to the emergence of a huge number of applications that act as additional components that expand the functionality of the underlying OS.

Customization

All users who do not want to put up with some limitations of the "Android" imposed by device makers are turning to so-called customization - changing individual components of the operating system or expanding its capabilities with additional software packages.

Route Rights

To perform serious manipulations with the software part of the "Android" -apparatus, the user will need superuser rights, as well as software that will manage the root-rights. One of the most popular solutions for managing superuser rights is the SuperSU application. It should be noted that the utility performs its functionality well, but sometimes causes problems, the most common of which is the inability to update the binary SU file. Let's take a closer look at the application itself, and also try to figure it out: if a binary SU file needs updating, what should we do in this case?

SuperSU program

SuperSU application can appear in the user's device in automatic mode after carrying out the procedure for obtaining the root-rights. In addition, many developers of custom firmware add to their solutions already installed SuperSU. If the root-rights are received, and the application for managing them is missing, you can download and install SuperSU from the Google Play Store.

Update SuperSU

Regardless of the way SuperSU was received and installed, after the first startup, the user receives a notification in most cases: "The SU binary file needs updating". Continue the use of the program quite often you can without updating. But still it is desirable to follow the recommendations of the developers and perform the procedures, according to the prompts of the program, when the binary SU file needs updating. It is not difficult to do the necessary actions, just click the "Update" button and select the appropriate update mode.

Emerging problems

It would seem that when using the program under consideration to manage the root-rights, the user should not have any difficulties. What can be easier: when a binary SU file needs updating, update it in three simple steps and continue to enjoy all the benefits that gives full access to the software part of the device.

But, as in many cases with other applications, the uninterrupted operation of SuperSU, unfortunately, is not guaranteed. Very often the following situation arises. After the user receives notifications from the program "the binary SU file needs updating," it tries to execute the procedure according to the prompts on the screen. The procedure is not always successful. Often, after rebooting the device, you receive an error message: "The binary SU file needs updating, the installation failed". How to be in this case?

Solution

There are several ways to prevent the above error. First, we must first take into account that SuperSU should be installed on a clean system that is not "littered" with other applications, especially in our case, those that exercise superuser rights management. 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 obtaining the root-rights, and also to install the SuperSU again.

The second thing that a user should remember is attentiveness and unhurriedness in carrying out the updating procedure. When you receive a notification that the binary SU file needs updating, you first need to try to update it in normal mode. At the same time, one should not forget about the necessity of having a Wi-Fi-connected Internet on the device (a connection via a mobile network in this case is not suitable). That is, after pressing the "Update" button in the SuperSU program window, select "Normal". Then wait for the necessary data to be downloaded from the Global Network and the end of the manipulations by the application itself, and after that - exit SuperSU and reboot the device.

In the case where the previous methods did not work and the binary SU file that already bore the edge must be updated again, we will have to resort to the method of installing / reinstalling the SuperSU via the modified "Android" -review. The most commonly used TWRP or CWM-recovery. To permanently forget about problems with SuperSU, we download from the Web a zip-package containing application files and install the resulting file through custom recovery. Such a cardinal method of solving the problem helps in most cases.

If the above methods do not help to fix problems with SuperSU, the user should think about the compliance of the firmware files and / or its components with the "Android" device. Very often the cause of many problems is precisely inappropriate or damaged installation files, especially if they were obtained from untrusted sources.
