Obtaining superuser rights, or Root access, remains one of the most popular procedures for mobile technology enthusiasts. Despite the fact that modern versions Android offer extensive capabilities out of the box, it is full control over the system that allows you to remove system garbage, install specialized modules and fine-tune kernel parameters. Using a personal computer in this process significantly increases the chances of success, since desktop utilities provide a more stable connection and allow you to execute complex commands. data-i="35">device manufacturer in most cases is canceled immediately after intervention in the software part of the smartphone.

ADB And Fastboot.
The procedure for flashing firmware and modifying a system partition requires not only technical training, but also an understanding of the risks. Guarantee In most cases, the device manufacturer's certificate is canceled immediately after interference with the software part of the smartphone. However, for those who are ready to take responsibility, unlimited customization opportunities open up that are not available in the standard mode of operation of the operating system.
In this material we will analyze in detail the preparatory stage, the necessary software and a step-by-step algorithm of actions for various scenarios. You will learn how to prepare bootloader, what tools are needed to work with the file system and how to avoid common mistakes that can turn the device into a "brick".
Preparing the workplace and the necessary software
The first step will be to organize a stable connection between the mobile device and a computer. You will need a high-quality USB cable, preferably original or certified, since cheap analogues often do not support data transfer, providing only charging. The computer must have an operating system installed Windows, Linux or macOS, as well as drivers for your specific smartphone manufacturer, without which the PC simply will not see the device in debugging mode.
A critical component is installation Android SDK Platform Tools. This package contains utilities adb and fastbootthat serve as a bridge between the computer's command line and the phone's operating system. Without these tools, interaction with the deep layers of the system is impossible. It is also worth downloading the archiver in advance, since many firmware and images are supplied in compressed format ZIP or RAR.
☑️ Preparation checklist
Don't forget to make a full backup of all important data. The process of obtaining superuser rights almost always involves full reset user data (Wipe Data). It is better to transfer photos, contacts and documents to cloud storage or an external hard drive in advance, so that in case of unforeseen circumstances you do not lose valuable information forever.
Unlocking the Bootloader
Most modern smartphones come with a locked one Bootloader is a special app code that runs before the operating system boots and checks the integrity of its components. While the bootloader is locked, it will not allow changes to be made to the system partition, which is the main obstacle to obtaining root access. Unlocking is the first and mandatory step, which differs depending on the brand of the device.
For devices Xiaomi you will need an official utility Mi Unlock Tool and linking your account to the device in a few days. Owners Samsung need to switch the phone to Download Mode mode and confirm unlocking through the developer menu. Devices Pixel and OnePlus often allow you to execute the unlock command directly through fastboot, which makes the process as fast as possible, but no less risky.
⚠️ Attention: The bootloader unlocking procedure automatically starts the mechanism Wipe Data, completely clearing the internal memory of the smartphone. All user files will be permanently deleted upon reboot.
What is OEM unlocking?
OEM Unlocking is a switch in the “For Developers” menu that gives software permission to change the boot partition. If this item is hidden or inactive, you will not be able to unlock Bootloader using standard methods, since the manufacturer has intentionally limited the capabilities of the device.
After successful unlocking, when you turn on the phone, you will most likely see a warning that the device is not certified or its integrity has been compromised. This is a normal reaction of the security system, which signals that Verity Boot is disabled and system files can now be modified. At this stage, the phone is ready to install a modified Recovery or direct patching of the boot image.
Installing ADB and Fastboot drivers
The correct operation of all tools depends on how the computer operating system recognizes the connected device. It often happens that the phone is detected only as a media device or charger, which makes it impossible to execute commands. To solve this problem, you must manually install universal Google USB Driver or specific drivers from the manufacturer, such as Samsung USB Driver or Xiaomi USB Driver
You can check the connection status through the command line. After connecting the phone in USB debugging mode, enter the command adb devices. If a device with a serial number and status appears in the list device, then the connection is established correctly. If you see the status unauthorized, look at the smartphone screen and confirm the debugging request by clicking "Always allow from this computer."
adb devices
fastboot devices
If the computer does not see the phone in Fastbootmode, you may need to manually install drivers through Windows "Device Manager". Find the unknown device with a yellow exclamation mark, select driver update and specify the path to the installed folder Platform Tools. This action will force the system to use the correct communication protocol for low-level operations.
The boot image patching method via Magisk
The most relevant and secure method of obtaining root access on modern versions of Android is using the utility Magisk. Unlike older methods, Magisk works systemless, which means it does not directly modify files on the system partition, but rather loads its modules at boot. This allows you to bypass security checks of banking applications and Google Pay services.
First, you will need an exact copy of the file boot.img (or init_boot.img on new devices), corresponding to the current firmware version installed on your smartphone. This file can be extracted from the stock firmware (ROM) or downloaded separately for your model. The file must be transferred to the phone and opened in the application Magisk, selecting the "Install" option and specifying the path to this image.
After the application creates the patched file (usually it is saved in the Download folder with the name magisk_patched.img), it must be returned to the computer. Next, the device is switched to Fastboot (bootloader) mode, and the file is flashed with the command:
fastboot flash boot magisk_patched.img
fastboot reboot
| File type | Purpose | Error risk |
|---|---|---|
boot.img |
Main boot kernel image | High (non-boot) |
recovery.img |
Recovery mode image | Medium |
vbmeta.img |
Integrity check table | Critical (bootloop) |
init_boot.img |
Initialization for Android 13+ | High |
It is important to understand that flashing the wrong file or a file from a different firmware version will lead to Bootloop (cyclic reboot). Therefore, the version of the patched image must match the version of the installed operating system. If, after rebooting, you see the Magisk logo in the application and the status is "Installed", congratulations - superuser rights are active.
Using custom Recovery (TWRP)
An alternative, although more complex, way is to install a modified recovery environment, such as TWRP (Team Win Recovery Project). This method is good because it allows you not only to obtain root access, but also to create full system backups (Nandroid backup), install custom kernels and modify system files directly through the file manager.
The process begins with finding a suitable image twrp.img specifically for your device model. There are no universal versions, since each smartphone has a unique memory layout and drivers. After downloading the image, it is flashed via Fastboot with the command fastboot flash recovery twrp.img, however, on many devices with activated protection AVB standard Recovery will immediately overwrite the modified one at the first boot.
⚠️ Attention: On devices with dynamic partitions (A/B partition), the flash recovery command may not work in the standard way. Often you need to use the command
fastboot boot twrp.imgfor a temporary download, and then perform a permanent installation inside TWRP.
After successfully installing TWRP, you need to download the ZIP archive with the installer Magisk and place it in the internal memory of the phone. Once in Recovery mode, select "Install", find the archive and confirm the installation. This method is considered more flexible, since TWRP allows you to roll back changes in case of failure, if you have a fresh backup.
Expert tip: Before flashing any image via Fastboot, always double check the file name and target partition. The flash command does not ask for confirmation a second time.
Checking rights and setting up access
After successful installation and the first boot of the system, you need to make sure that the rights work correctly. Open the application Magisk —at the top of the screen the green indicator with the words “Installed” should be lit. The version and security status will also be indicated there. For additional testing, you can download an application from the Play Market Root Checkerthat will run a test script and display the result.
An important step is setting up access for applications. By default, no application has superuser rights. When you first run a app that requires elevated privileges (for example Titanium Backup or CpuFetcher), a prompt from Magisk will appear on your screen. You can select "Grant forever", "Grant for 10 minutes" or "Refuse".
To increase security and hide the fact of rooting from banking applications, you need to activate the function Zygisk in Magisk settings and enable the "Exclusion List" (formerly known as Magisk Hide). To this list you need to add banking applications, Google Pay and other services that block operation on modified devices. After this, it is recommended to clear the data of these applications and restart the smartphone.
What to do if the bank application does not work?
Even with hidden rights, some banks can detect an unlocked bootloader. In this case, it may be necessary to install additional modules, such as "Universal GMS Doze" or "Shamiko", which mask changes in the system more deeply. Uninstalling Google Play Services updates and installing an older, stable version also helps.
Is it possible to update Android after receiving Root?
Over-the-air (OTA) updates on rooted devices usually fail because system integrity is compromised. To update, you will have to manually download the full firmware image, patch the boot image again through Magisk and flash it again, while saving all the data (if the versions are compatible).
How to completely remove root access?
The easiest way is to open the Magisk application, click the "Delete" button and select "Full removal". The system will automatically restore the original boot image and reboot to a clean state. If this method does not work, you will need to flash the stock boot.img via the computer.
root access give full control, but require constant attention to security updates and application compatibility.
To summarize, we can say that installing root access via a PC is a powerful tool in the hands of an experienced user. It allows you to extend the life of an old device, speed up its operation and remove advertising at the system level. However, this process requires care, strict adherence to instructions and an understanding that you take responsibility for the performance of your gadget.
