The world of Android rooting is vast and complex, offering users a plethora of options to customize and enhance their device’s performance. One of the most popular tools in this realm is SuperSU, a superuser access management tool that allows users to grant or deny root access to other applications. However, the installation process of SuperSU can sometimes encounter issues, leading to the frustrating “Supersu installation failed” error. This article aims to provide a detailed and step-by-step guide on how to fix this issue, ensuring that you can successfully install SuperSU and enjoy the benefits of rooting your Android device.
Understanding The Supersu Installation Failed Error
Before diving into the solutions, it’s crucial to understand the possible reasons behind the “Supersu installation failed” error. This error can occur due to a variety of factors, including incompatible device firmware, insufficient permissions, corrupted system files, or conflicting applications. Each of these factors can prevent the successful installation of SuperSU, requiring different approaches to resolve the issue.
Checking For Incompatible Firmware
One of the primary reasons for the “Supersu installation failed” error is incompatible device firmware. Outdated or modified firmware can lead to compatibility issues with SuperSU, making it essential to check and update your device’s firmware before attempting the installation. You can check for firmware updates in your device’s settings under the “About phone” or “Software update” section. Ensuring your device is running on the latest firmware can significantly improve the chances of a successful SuperSU installation.

Enabling USB debugging in your device’s developer options and ensuring that your device is properly rooted can help alleviate these issues. Additionally, granting root access to the installer is crucial for the successful installation of SuperSU.
Step-by-Step Solutions To Fix Supersu Installation Failed
Now that we’ve explored the common reasons behind the “Supersu installation failed” error, let’s proceed to the step-by-step solutions to fix this issue.
Method 1: Reinstalling SuperSU
The first method involves reinstalling SuperSU from scratch. This approach can help resolve issues related to corrupted system files or conflicting applications. To reinstall SuperSU, follow these steps:
- Open the Google Play Store or the SuperSU official website and download the SuperSU installer.
- Enable USB debugging on your device and connect it to your computer.
- Open the command prompt or terminal on your computer and navigate to the folder containing the SuperSU installer.
- Execute the installer using the appropriate commands (e.g., “adb push SuperSU.zip /sdcard/” followed by “adb shell su -c ‘tar -xvf /sdcard/SuperSU.zip'”).
Method 2: Using TWRP Recovery
Another effective method is using TWRP (Team Win Recovery Project) recovery to install SuperSU. TWRP offers a more straightforward and user-friendly interface for installing recovery flashables like SuperSU. Here’s how you can use TWRP:
- Download and install TWRP recovery on your device using Fastboot or another compatible method.

Advanced Troubleshooting Techniques
If the above methods fail to resolve the “Supersu installation failed” error, it may be necessary to employ more advanced troubleshooting techniques. This can include manually editing system files, using ADB commands to push and install SuperSU, or utilizing other root management tools as alternatives to SuperSU.
Manual System File Editing
Manual editing of system files can be a risky but effective method to resolve deep-seated issues. This involves editing the su binary permissions or manually installing SuperSU by pushing the necessary files to the system partition. However, this approach requires a thorough understanding of Android system files and the use of ADB commands, making it more suitable for experienced users.
Using ADB Commands For Installation
Using ADB (Android Debug Bridge) commands can provide a more controlled environment for installing SuperSU. By pushing the SuperSU zip file to the device and then executing the installation script via ADB shell, users can bypass certain compatibility issues. This method requires the Android SDK to be installed on the computer, along with USB debugging enabled on the device.
Conclusion And Recommendations
Resolving the “Supersu installation failed” error requires patience, persistence, and a clear understanding of the underlying causes. By following the step-by-step guides and troubleshooting techniques outlined in this article, users should be able to successfully install SuperSU and enjoy the enhanced functionality and customization options it provides.
