Receiving root access on a device running an operating system Android opens up endless possibilities for the user for customization and deep optimization of the gadget. Essentially, this is an analogue of administrator rights in Windows, allowing you to make changes to system files, remove pre-installed software and manage power consumption at the hardware level. However, the process is not without risks and requires careful preparation, since an error at any stage can turn the phone into a “brick.”
In this article we will analyze in detail modern methods of obtaining full access to the file system, which are relevant for most devices produced in 2026-2026. Old methods using one-button apps like KingRoot have become almost ineffective due to increased security protection in new versions of the OS. Now the path to superuser lies through unlocking the bootloader and installing specialized access rights managers.
Before taking active steps, you need to realize that the procedure for obtaining superuser rights will inevitably lead to loss of warranty on the device in most service centers. Manufacturers consider tampering with the system partition a violation of operating conditions. Moreover, some banking applications and games with anti-cheat protection may refuse to work on a rooted device without additional manipulations to hide the fact of system modification.
Preparing the device and backing up data
The first and most critical step is to create a full backup of all user data. During the process of unlocking the bootloader, which is a prerequisite for obtaining root access on most modern smartphones, the device is completely reset to factory settings. This means that all photos, contacts, messages and installed applications will be permanently deleted.
It is recommended to use not only cloud services, but also local copying to a computer or external drive. It's especially important to save media folders and documents that often don't sync automatically. To create a complete backup of the system partition (if you plan to experiment with custom recovery), it is best to use the mode Fastboot or specialized software for PC.
⚠️ Attention: The process of unlocking the bootloader is irreversible in some smartphone models (for example, devices from Verizon or some Huawei models). Make sure your specific model supports this procedure before you begin.
You will also need to enable Developer Mode on your device. To do this, go to Settings → About phone and click seven times on the item Build number. After a message appears stating that you have become a developer, go to the new menu For developers and enable the option USB debugging. Without this parameter, the computer will not be able to send commands to the smartphone.
☑️ Preparation for receiving Root
Unlocking the bootloader
A bootloader is a app that is launched by the operating system and verifies the digital signature of the loaded software. By default, it is blocked by the manufacturer to prevent the installation of unofficial firmware and modified kernels. Unlocking the bootloader is the first technical step to obtain root access, but it varies depending on the brand of the device.
For devices Xiaomi a special utility Mi Unlock Tool is required and a wait of 3 to 7 days after linking the account to the device. Owners of smartphones Google Pixel or OnePlus can unlock directly through the console by connecting the phone to the PC. A universal command for many devices looks like this:
fastboot flashing unlockAfter entering the command, a warning about data loss and the need to confirm the action with the volume buttons will appear on the smartphone screen. Confirmation will start the memory clearing and reboot process. It is important to understand that on some devices (for example, from US carriers), unlocking the bootloader may be completely prohibited at the software level.
What is OEM Unlock?
The OEM Unlock option in the developer menu allows software unlocking of the bootloader. If this item is missing or inactive, your carrier may have blocked this feature, or the device has not yet been verified by the manufacturer's servers.
It is worth noting that after unlocking the bootloader, some security features, such as Google Pay or working with protected content Widevine L1may no longer function fully. This is due to a violation of the Android security trust chain (SafetyNet/Play Integrity API). It is possible to restore the operation of these services, but this will require additional settings after obtaining root access.
Installing custom recovery (TWRP)
The standard recovery menu (Stock Recovery) has extremely limited functionality and does not allow you to install modified files or create full system backups. For further actions, we will need to install a custom recovery, the most popular and functional of which is TWRP (Team Win Recovery Project).
The installation process is carried out through the mode Fastboot. You need to download a recovery image that corresponds specifically to your device model (the model code must match completely). The command for flashing the firmware looks like this:
fastboot flash recovery twrp_image_name.imgImmediately after flashing the firmware, it is important to prevent automatic loading into the system, since the standard bootloader can replace the custom recovery with the stock one. To do this, use a combination of buttons (usually Volume Down + Power) to enter directly into the installed TWRP. In the recovery menu, you will have access to the device’s file system and will be able to install zip archives with modifications.
⚠️ Attention: When you first boot into TWRP, the system may ask for permission to make changes. Be sure to swipe to confirm (Swipe to Allow Modifications), otherwise the recovery will be reset upon the first reboot.
If you have a device with dynamic partitions (A/B partition), the process may differ. In such cases, it is often necessary to install recovery directly into the active slot or use specialized scripts. Always check the instructions for a specific model on specialized forums such as 4PDA or XDA Developers, since there is no universal solution for all processor architectures.
Installing Magisk and obtaining superuser rights
Today the de facto standard for management root access is the application Magisk. Unlike older methods (SuperSU), Magisk works on the systemless principle, that is, it does not make direct changes to the system partition. This allows you to hide the fact of obtaining root access from banking applications and games, as well as support OTA updates.
To install, you need to download the Magisk APK file, rename its extension to .zip and flash it through the menu Install in TWRP mode. An alternative method, which is often necessary for devices without custom recovery, involves patching the bootloader image (boot.img). You extract boot.img from the official firmware, open it through the Magisk application on your phone (the "Install" button → "Select and patch file"), and then flash the resulting file magisk_patched.img via Fastboot.
| Characteristics | SuperSU (Outdated) | Magisk (Current) | KernelSU (New) |
|---|---|---|---|
| Implementation method | Changing the system partition | Systemless (no change system) | At the kernel level |
| Hiding Root | No or difficult | Built-in function (MagiskHide/Zygisk) | High degree of secrecy |
| Module support | Limited | Wide module support | Kernel module support |
| Working with banks | Problematic | Possible with configuration | Best compatibility |
After successful installation and reboot, the Magisk application will appear on the system. If you see a More Settings button or a prompt to complete installation when you open an app, follow the onscreen instructions. The presence of a superuser icon in the list of applications confirms the successful acquisition of rights. You can now grant or deny root access to any installed apps.
Use the Zygisk feature in Magisk settings to hide root access more effectively. This allows you to embed code into application processes, which is necessary for modern detection bypass methods to work.
Checking rights and access control
To make sure that rights work correctly, you can use specialized utilities, for example, Root Checker. However, a more reliable method is to try to execute commands through the terminal. Install any terminal emulator and enter the command su. If the system asks for confirmation of access rights (a pop-up window from Magisk) and after confirmation the command prompt symbol changes from $ to #, then you have successfully entered superuser mode.
Access control is carried out through the Magisk application interface in the "Superuser" section. This displays a list of all applications that have requested elevated privileges. You can set up rules for each application separately: grant access forever, only once, or completely deny it. Proper management of this list is critical to the security of the device.
Do not grant root access to applications from unknown sources. Malware with root access can gain full control of the device, stealing passwords, encryption keys, and personal data. Always check the developer's reputation before clicking the "Grant" button in the request pop-up window.
Never grant root access to applications that do not require them for the stated functionality. Ordinary flashlights or calculators do not need access to system files.
Possible problems and solutions
In the process of obtaining root access, users often encounter a cyclic reboot (bootloop), when the smartphone constantly reboots and cannot load the operating system. This may happen due to the Magisk version being incompatible with the Android version or the bootloader image being corrupted. In most cases, the solution is to re-enter recovery mode and install the corrected file or completely remove Magisk through the "Uninstall" menu in the application itself (if you have access) or through a special command in the recovery terminal.
Another common problem is banking applications not working. Even if you have root access, Google's modern security systems (Play Integrity) can block the operation of fintech applications. To solve this problem, you need to enable the function Zygiskin the Magisk settings, install the module Play Integrity Fix and add banking applications to the exclusion list (DenyList). This process requires constant updating of modules, since Google is constantly changing detection algorithms.
⚠️ Attention: Interfaces and menu names in different versions of Android and manufacturers' shells may differ. If you do not find an exact match of the menu item, look for a similar one or check the documentation for your specific model.
It is also possible that problems with Wi-Fi or Bluetooth may occur after flashing a custom kernel or recovery. This is due to the fact that some drivers are strictly tied to the stock firmware kernel version. In this case, it is recommended to return to the stock kernel, while maintaining root access through the boot image patching method discussed above.
Frequently asked questions (FAQ)
Will getting root access reset the Knox counter on Samsung?
Yes, on devices Samsung unlocking the bootloader and obtaining root access irreversibly trips the Knox physical fuse (0x1). This permanently disables features like Samsung Pay, Secure Folder, and Secure Folder, even if you later return to stock firmware. It is not possible to reset this counter programmatically.
Is it possible to get OTA updates after installing Magisk?
Yes, this is possible thanks to Magisk's systemless method. However, the update process requires specific actions: you cannot click the "Restart" button immediately after installing the update. You need to go to the Magisk application, select “Install” → “Install in an inactive slot (after OTA)”, and only after completing this procedure, reboot the device. Otherwise, you will lose root and access to encrypted data.
Is it safe to use banking applications with root access?
Using banking applications on a rooted device carries increased risks. Although Magisk allows you to hide access rights, the constant arms race between Magisk developers and bank security means that access can be blocked at any time. For maximum security of financial transactions, it is recommended to use a separate device without modifications.
What to do if the phone went into bootloop after flashing the firmware?
Try entering Recovery mode (TWRP). If the menu loads, try wiping the cache (Wipe Cache/Dalvik). If this does not help, you need to reflash the stock image of the bootloader (boot.img) and recovery (recovery.img) via Fastboot from your computer. In extreme cases, you will need to completely flash the device with official software via Download mode (for Samsung) or Fastboot (for others).
Do you need to unlock the bootloader for Magisk to work?
In the vast majority of cases, yes. Magisk requires the ability to modify the boot section, which is not possible with a locked bootloader due to digital signature verification. There are rare exceptions for some older devices or specific exploits, but for modern smartphones, unlocking the bootloader is a must.
