Getting root access on a device running the Android operating system is a process that opens up almost limitless customization and optimization possibilities for the user. Smartphone owners often face limitations imposed by manufacturers, such as pre-installed system applications that cannot be removed, or lack of access to fine-tuning the kernel. Super user allows you to bypass these barriers, turning your gadget into a powerful tool for experimentation.
However, before starting the procedure, you must be clearly aware of the risks. Tampering with system partitions can lead to loss of warranty, disruption of banking applications and, in the worst case, turning the device into a brick. Modern versions of Android, such as Android 13 and Android 14have stronger boot protection, making the process more difficult than it was a few years ago. However, if you take all precautions and use up-to-date software, obtaining administrator rights remains a completely doable task.
In this article we will analyze in detail modern methods of obtaining privileges, using tools like Magisk and KernelSU, which allow you to hide the fact of interference from applications with security checks. You'll learn how to prepare your device, what utilities you'll need on your computer, and what to do if things don't go according to plan. The willingness to sacrifice stability for complete control is the first step towards freedom of your system.
Device preparation and risk assessment
Before starting any manipulations, it is critical to create a complete backup of all data. The process of obtaining superuser rights almost always requires clearing the internal memory of the device, as it is associated with unlocking the bootloader. Save photos, contacts and documents to cloud storage or external storage so as not to lose them forever.
The next step is to check your smartphone model and firmware version. Not all devices officially support bootloader unlocking. For example, manufacturers like Sony or Xiaomi provide unlock codes, while Huawei or American carrier versions of phones often block this feature at the hardware level. You need to find the exact model in the settings by going to Settings → About phone → Software information.
⚠️ Attention: Unlocking the Bootloader irreversibly erases all user data from the device. Make sure you save important files before executing the fastboot command.
It is also worth enabling USB debugging mode and advanced settings for developers. Without this, the computer will not be able to interact with the phone in low-level access mode. Activation is done by repeatedly clicking on the build number in the “About phone” menu, after which a new section will appear in the main settings menu. Turn on the item USB debugging and confirm permission to access from this computer when you first connect the cable.
Unlocking the bootloader
Unlocking the bootloader - This is a fundamental step, without which installing a modified_recovery_ or direct access to the system partition is not possible. The bootloader is responsible for verifying the system signature when the device is turned on. When locked, it allows the launch of only official images signed with the manufacturer's cryptographic key.
To perform this procedure, you will need a computer with drivers ADB and Fastbootinstalled. Connect your smartphone in the off state by holding down a certain key combination (usually the power button and the volume down button) to enter Fastboot mode. After connecting to the PC, open the command line and enter the command to test the connection: fastboot devices. If the device is displayed, you can proceed to unlocking.
The unlocking command depends on the manufacturer. For most devices on chipsets Qualcomm and MediaTek the standard syntax is used. Enter in the terminal:
fastboot flashing unlockA warning about data loss and voiding the warranty will appear on the smartphone screen. Confirm the action with the volume buttons. The process may take several minutes, after which the device will reboot into the cleaned system. Some brands, such as Xiaomi, require preliminary linking of the account and waiting from 3 to 7 days before issuing permission to unlock through the official Mi Unlock utility.
☑️ Checklist before unlocking
Installing custom Recovery (TWRP)
After successfully unlocking the bootloader, the next logical step is to install a modified recovery environment. Standard recovery from the manufacturer has limited functionality and does not allow the installation of unsigned zip archives. TWRP (Team Win Recovery Project) is the gold standard in this area, providing a convenient touch interface and support for file systems.
You need to download a recovery image that strictly matches your device model and code name. Using an image from another model will result in touch control failure or the device completely refusing to boot. The file usually has the extension .img. Place it in the platform tools folder on your computer. Switch the phone to Fastboot mode again and run the firmware command:
fastboot flash recovery twrp_image_name.imgImportant nuance: immediately after flashing the firmware, you cannot boot into a regular system, otherwise the stock recovery will overwrite the installed TWRP. You must immediately hold down the key combination to enter recovery mode. In the TWRP environment, the first step is to make a full backup of the current system (Nandroid backup) in order to have a rollback point in case of unsuccessful experiments with root access.
⚠️ Attention: On devices with data encryption (FBE), the touch screen in TWRP may not work right away. In this case, you will need to disable encryption via the console or install a special patch before installing superuser rights.
Installing Magisk and obtaining Root access
Today Magisk from the developer topjohnwu is the most popular and effective solution for obtaining root access. Its main advantage over older methods (like SuperSU) is its systemless root system. Magisk makes changes to the boot image rather than modifying the system partition directly, which allows it to pass Google Play Integrity (formerly SafetyNet) security checks.
The installation process begins by downloading the Magisk APK file to your smartphone. However, patching the boot image is often required for correct operation. Copy the file boot.img (extracted from the official firmware of your model) to your phone. Open the Magisk application, select “Install” and click “Select and patch file”. Specify the path to the copied image. After the process is completed, a file with the name of the form will appear in the Download folder magisk_patched_[random].img.
Return this patched file to the computer and put the phone into Fastboot mode again. Execute the final command for flashing the modified kernel:
fastboot flash boot magisk_patched.imgAfter the reboot, the Magisk application will appear in the system. If it opens and the version number is displayed at the top, and there is a checkmark or version number in the “Root” line, then access was obtained successfully. You can manage permissions for each application individually right from the Magisk interface.
What is Zygisk and why is it important?
Zygisk is an implementation of Magisk within the Zygote process, which is responsible for creating all applications in Android. Enabling Zygisk allows modules to be embedded in application processes, which is necessary for the operation of modern modules for hiding root access and changing system parameters on the fly.
Alternative methods and KernelSU
Recently, a project has been gaining popularity KernelSU, which offers a fundamentally different approach to managing privileges. Unlike Magisk, which runs in user space, KernelSU is integrated directly into the Linux kernel (GKI - Generic Kernel Image). This provides a deeper level of isolation and makes root detection by third-party applications extremely difficult.
Using KernelSU requires your device to be running kernel version 5.10 or higher with GKI support. You can check this using third-party utilities or terminal commands. If your device supports this technology, you can install the module via the same TWRP or flash a kernel image with KernelSU already installed. For ordinary users who do not want to compile the kernel manually, there are ready-made firmware from enthusiasts on the forums 4PDA or XDA Developers.
A comparison of popular solutions for obtaining superuser rights is presented in the table below:
| Characteristics | Magisk | KernelSU | SuperSU (Outdated) |
|---|---|---|---|
| Implementation method | Systemless (boot image) | Kernel | Modification of /system |
| Secrecy from banks | High (with modules) | Very high | Low |
| Requirements kernel | Any | GKI 5.10+ | Any |
| Modules support | Huge base | Growing base | None |
The choice between Magisk and KernelSU depends on the technical savvy of the user and the specifics of the device. For most use cases, Magisk remains the most versatile and easy-to-configure option, supporting a wide range of modules for changing system behavior.
If banking applications stop working after installing Root, use the MagiskHide or Zygisk DenyList module in Magisk settings to hide the presence of rights from specific applications.
Possible problems and solutions
The process of obtaining root access rarely goes perfectly smoothly for all users. One of the common problems is “bootloop”, when the phone endlessly reboots before reaching the desktop. This usually occurs due to incompatibility of the patched boot.img image with the kernel version or errors in the firmware. In this case, you need to enter Fastboot mode again and flash the original, stock image of the boot partition that you saved during the preparation stage.
Another common difficulty is the failure of the touch screen to work in Recovery mode. This is due to the fact that the touchscreen drivers in the stock kernel may not be initialized in the TWRP environment. The solution is to find a special version of TWRP for your model or use ADB commands to manage recovery from your computer if the sensor is not responding. Also, the problem can be solved by disabling data encryption through the command format data in the recovery console.
⚠️ Attention: Menu interfaces and item names may differ depending on the version of Android and the manufacturer’s shell (MIUI, OneUI, ColorOS). Always check the relevant forum threads for your specific model before executing commands.
If, after obtaining root access, the device begins to quickly discharge or overheat, it is possible that one of the installed modules conflicts with the system. Try booting into Safe Mode (usually holding down the power button on the logo while booting) or uninstalling recently installed modules through the Magisk app. In extreme cases, a full reset of the settings (Wipe Data) through the Recovery menu helps.
The key to successfully obtaining Root is having the original stock firmware image (boot.img) in case you need to urgently restore the device to its original state.
Will the warranty expire after obtaining root access?
In most cases Unlocking the bootloader and becoming root will void the software warranty. Manufacturers may refuse free repairs if they find signs of tampering. However, if you return the device to its original state (lock the bootloader and flash the stock firmware), physical defects may be accepted under warranty, but it can be difficult to prove the fact of interference.
Will banking applications work with Root?
By default, banking applications will (detect) root access and refuse to launch. However, by using Magisk with the Zygisk function enabled and adding applications to the exclusion list (DenyList), as well as installing the Play Integrity Fix module, you can successfully hide the presence of rights and make the banks work correctly.
Is it possible to remove root access and return everything as it was?
Yes, this is possible. The Magisk app has a "Remove Magisk" button with an option to restore the stock image. After this, you need to block the bootloader again with the command fastboot flashing lock. Please note that locking the bootloader will again erase all data on the device, so be sure to make a backup before this step. Is it dangerous to root a phone with a MediaTek processor? In addition, tools for working with MediaTek (SP Flash Tool) require special care, since an error in the firmware address can lead to the loss of the IMEI partition and the inability to make calls. It is recommended to carefully study the instructions specifically for MTK chipsets.
Is it dangerous to Root a phone with a MediaTek processor?
MediaTek processors have their own features, such as SV6 protection, which can prevent the bootloader from being unlocked. In addition, tools for working with MediaTek (SP Flash Tool) require special care, since an error in the firmware address can lead to the loss of the IMEI partition and the inability to make calls. It is recommended to carefully study the instructions specifically for MTK chipsets.
Why do you need Root if Android is already functional?
root access is needed for deep automation (for example, through Tasker), complete removal of undeletable garbage from the operator, installation of specific Xposed modules to change the interface, creating complete backups of application data (Titanium Backup) and fine-tuning of processor power consumption, which is inaccessible to the average user.
