Obtaining superuser rights on a device under control Android opens up almost limitless possibilities for system customization for the owner of a smartphone or tablet. In a typical configuration, Google's mobile operating system restricts access to critical sections of the file system for the sake of security and stability. However, for advanced users, these restrictions often become an obstacle to removing pre-installed system junk, deeply customizing the interface, or using specialized software.
The process of granting superuser status to an application, known among enthusiasts as rooting (rooting), requires care and strict adherence to instructions. Errors at any stage can lead to loss of warranty, blocking of the device, or complete inoperability of the gadget. In this article, we will analyze in detail modern methods of obtaining privileged rights, current tools and precautions that must be observed before starting the procedure.
Preparing the device and understanding the risks
Before you begin modifying the system partition, you need to understand all the consequences of this step. obtaining root access root means tampering with the integrity of the software, which automatically voids the manufacturer's warranty in most cases. In addition, many banking applications and contactless payment services by default refuse to work on rooted devices for security reasons. Google Pay or Samsung Pay by default they refuse to work on rooted devices for security reasons.
The first and most important step is to create a complete backup of all important data. Even if the procedure is successful, there is a risk of accidentally deleting information when unlocking the bootloader. It is recommended to use cloud storage or connect your smartphone to your computer to copy photos, contacts and documents to external media. Ignoring this step may result in permanent loss of personal information.
It is also worth checking the battery level of your device. The process of flashing or modifying the bootloader requires stable power, and suddenly turning off the smartphone at a critical moment can turn it into a brick. Make sure that the battery is charged at least 60-70%, or better yet, connect the device to a power source during all manipulations.
⚠️ Attention: The procedure for obtaining root access is irreversible in terms of warranty status. Some manufacturers, such as Samsung or Huawei, may permanently block the ability to use protected functions (for example, Knox or fingerprint unlocking) even after returning to factory settings.
Unlocking the bootloader
Modern Android devices come with a locked bootloader, which prevents installation of software not signed by the manufacturer. Without unlocking Bootloader obtaining superuser rights is impossible, since you will not be able to write a modified recovery or kernel image to the system partition. Unlocking methods differ radically depending on the brand of your smartphone.
For devices Google Pixel and many models on pure Android, the procedure is simplified as much as possible and is performed through the mode Fastboot. You will need to enable USB debugging in the developer menu, connect the phone to the PC and run the command fastboot flashing unlock. A warning about data loss will appear on the devices, confirmation of which will erase all information from the internal memory and unlock the bootloader.
The situation with devices Xiaomi, OnePlus or Sony is more complicated. Often, registration is required on the manufacturer's official website, waiting a period of 7 to 30 days and using proprietary utilities, such as Mi Unlock. Some brands, for example Huawei or Honor, in recent years have completely closed the possibility of officially unlocking the bootloader for ordinary users, which makes rooting such devices extremely difficult or impossible without the use of paid services.
- 🔓 Unlocking the bootloader always leads to a complete reset of the device to factory settings (Wipe Data).
- 🛡️ After unlocking, the Android security system may mark the device as compromised, which affects the operation of DRM content (Netflix in HD/4K).
- ⏳ For some brands, there is a mandatory waiting period (timeout) between the permission request and the unlock itself.
Choosing a tool to obtain root access
The era of universal applications for one-click rooting, such as old versions KingRoot or Towelroot, is almost over. On modern versions of Android (starting from 8.0 and higher), these methods do not work due to enhanced kernel protection mechanisms SELinux and bootloader verification. Today, the gold standard in the Android modification industry is considered to be a tool developed by top developer topjohnwu. It is unique in that it implements a system-less approach. Instead of directly modifying the system partition, it is embedded in the boot image, intercepting requests for superuser rights on the fly. This allows you to hide the fact of having root access from applications that do not welcome them, using the Magisk, developed by top developer topjohnwu.
Magisk is unique in that it implements a system-less approach. Instead of directly modifying the system partition, it is embedded in the boot image, intercepting requests for superuser rights on the fly. This allows you to hide the fact of having root access from applications that do not welcome them, using the function MagiskHide function (or Zygisk in new versions). In addition, Magisk supports modules that expand the functionality of the system without the need for flashing.
An alternative to Magisk is KSU (KernelSU), which is integrated directly into the Linux kernel on which Android runs. This method provides an even deeper level of secrecy and stability, but requires a custom kernel that supports this function or self-compilation of the kernel for a specific device. For most users, Magisk remains the most accessible and universal solution.
Always download the Magisk utility only from the official repository on GitHub. Third-party sites often distribute modified versions with malicious code that can steal your data.
Step-by-step guide for installing Magisk
The process of installing superuser rights using Magisk requires a computer, an installed driver ADB/Fastboot and the original bootloader image (boot.img) for your version firmware. You can find this file on developer forums (for example, w3bsit3-dns.com or XDA Developers) or extract it from the official firmware downloaded from the manufacturer’s website. An exact match between the version of the image and the installed firmware is critical.
After the file boot.img is received and transferred to the smartphone, install the Magisk application (APK file). Launch the application, click the "Install" button next to Magisk and select the "Patch boot image" option. The application will process the file and create a new, modified image, which is usually saved in a folder Download under the name magisk_patched_[random].img.
Next, put the smartphone into mode Fastboot (usually by holding down the volume down button when turning it on) and connect it to the computer. Open the command line on your PC and enter the command to flash the patched image. Make sure that you are using the correct file name that you received in the previous step.

fastboot reboot
After the device reboots, the Magisk application should appear on the system, which will confirm the successful installation. If your smartphone boots normally, check for the superuser icon in the list of applications. Now you can grant access rights to other apps through the Magisk interface.

Configuring access for applications and modules
After successfully obtaining root access, access control is carried out through the app Magisk Manager. The first time an application asks for superuser rights, a pop-up window will appear on the screen asking for confirmation. You can grant access once, grant it forever, or deny it. It is recommended to grant rights only to apps that you fully trust, since with root access the application gains full control over the system.
One of the key functions of modern rooting is the use of modules. Modules are packages that can change system fonts, improve audio quality, block system-level ads, or emulate other devices. Installation of modules occurs directly from the Magisk interface in the "Modules" tab. After installing the module, you need to reboot the device to apply the changes.
An important aspect is to hide the fact of rooting. Many banking applications use API SafetyNet or new Play Integrity API to check system integrity. To bypass these checks, you need to enable Zygisk in Magisk settings, add the desired applications to the exclusion list (DenyList) and, possibly, install additional modules, such as Play Integrity Fix. Without these settings, Google Pay services may not function.
| Tool | Access type | Installation complexity | Hide from applications |
|---|---|---|---|
| Magisk | System-less | Average | High (via Zygisk) |
| KernelSU | Kernel | High | Very High |
| SuperSU | System | Low (outdated). root access may change with the release of new versions. Always check the official project documentation on GitHub or relevant forums before changing critical settings. | Absent |
| APatch | Kernel | High | High |
⚠️ Attention: Interfaces and names of functions in applications for managing root access may change with the release of new versions. Always check the official project documentation on GitHub or dedicated forums before changing critical settings.
What is Zygisk?
Zygisk is a technology for injecting Magisk code into the Zygote process, which is the parent of all Android processes. This allows modules to work more efficiently and hide the presence of root access from applications that check the system, since modifications occur at the process memory level, rather than system files.
Possible problems and their solutions
When using a rooted device, users may encounter a number of problems, from cyclic reboots (bootloop) to failure of specific functions. If after installing the module or changing the settings, the smartphone stops booting, first try booting into safe mode. On most devices, this is done by holding down the volume down button while the manufacturer's logo appears. In safe mode, all third-party Magisk modules are disabled, which allows you to remove the problematic component.
If the device goes into an endless reboot and does not respond to safe mode, you will need access to Recovery mode. If you have a custom recovery installed, such as TWRP, you can go to the file manager directly in the recovery and delete the folder with modules along the path /data/adb/modules. This will roll back all changes made by the modules and allow the system to boot.
Problems with the operation of banking applications are often solved not only by setting DenyList. Sometimes you need to completely flash the stock boot image without a Magisk patch if you urgently need to use the service and don’t have time to fine-tune the hiding. Remember that system verification may be broken, and in some cases a factory reset is required after removing root access to fully restore all services.
The most common cause of problems after rooting is the incompatibility of installed modules with the Android version or conflicts between them. Remove the modules one by one for diagnostics.
Does rooting void the warranty on a smartphone forever?
In most cases, yes, the fact of interference in the software is recorded at the counter level (for example, Knox on Samsung), which cannot be reset programmatically. However, if you unlock the bootloader and then lock it back and return to stock firmware, some manufacturers may accept the device for repair if the problem is not software related. But you shouldn’t count on it.
Is it possible to get system updates over the air (OTA) with root access?
Usually no. The presence of a modified boot image violates the integrity of the system, and the official update will not be installed or will result in an error. To update, you need to temporarily return the stock bootloader image, install the OTA update, and then patch the new image again via Magisk.
Is it safe to enter bank card details on a rooted phone?
Technically, this is possible with the correct root hiding setting (MagiskHide/Zygisk), but the risks remain. If a malicious application gains root privileges, it can intercept keystrokes or take screenshots. It is recommended to use a separate device for financial transactions or be extremely careful with issuing rights.
How to completely remove root access from a device?
The easiest way is to open the Magisk application, click the "Delete" button and select "Full removal". The application will automatically restore the original boot image and delete all its files. After the reboot, superuser rights will be completely revoked, but unlocking the bootloader may remain unless you manually block it via Fastboot.
