Obtaining privileged access to the operating system of a mobile device opens up unlimited possibilities for the user to customize and manage the hardware. However, the standard interface Android deliberately limits these functions for security and stability reasons. That is why the question of how to gain complete control over the system remains one of the most popular among advanced enthusiasts.
Using a personal computer for this procedure is the most reliable method, since the PC has large computing resources and a stable connection to the device. Unlike one-button applications installed directly on the phone, methods using ADB and Fastboot allow you to interact more deeply with system partitions. This reduces the risk of accidental damage to the file structure if you act strictly according to the instructions.
In this material we will analyze in detail the process of rooting through a computer, consider the necessary tools and pay special attention to safety precautions. You'll learn how to prepare your device, what drivers you'll need, and what pitfalls you might encounter on your way to superuser status. Remember that any manipulation of system files carries certain risks.
Preparation of the workplace and necessary tools
Before taking active steps, you need to collect the entire arsenal of software. The basic element is the installation of drivers ADB and Fastbootthat provide communication between the computer operating system and the smartphone. Without these components, the PC simply will not see the device in debugging mode, and all subsequent commands will be useless.
A high-quality USB cable is also critically important. Cheap cables that come with some accessories often only support charging mode and do not transfer data. Using such a cable will make it impossible to execute any commands through the terminal. It is recommended to use the original cable from your smartphone or a certified analogue that supports high-speed data transfer.
Specialized utilities are often used to directly implement superuser rights. Among them one can highlight KingRoot, iRoot or more advanced tools like Magisk. The choice of a specific app depends on the version Android and processor model of your device. There is no universal solution for all gadgets, so you should study the forums dedicated to your model in advance.
⚠️ Attention: Before starting any work, be sure to create a complete backup copy of all important data. The process of obtaining root access can lead to complete deletion of information from the internal drive.
☑️ Preparing for rooting
Activate developer mode and USB debugging
Standard security settings Android hide the ability to interact with the system from the outside. To open access, the user must activate the hidden menu. To do this, go to the Settings → About phone section and find the “Build number” item. You must quickly click on this item seven times in a row until the system reports that the developer mode has been successfully activated.
After the new item appears in the main settings menu, go to the section System → For developers. Here you are interested in the “USB Debugging” option. Enabling this switch allows the computer to send commands to the device and receive responses from the system. Without enabling this function, further steps cannot be completed.
When you first connect your smartphone to a computer with debugging enabled, a request to confirm the RSA key will appear on the device screen. This is a security mechanism to ensure that only a trusted computer has debugging access. You must check the box “Always allow from this computer” and click “OK”, otherwise the connection will be broken after each cable reconnection.
If the “Build number” item is not found right away, use the search in the phone settings by entering the word “assembly” or “build”.
Unlocking the bootloader
Most modern smartphones come with a locked bootloader, which prevents the installation of modified recovery images and system partitions. Unlocking Bootloader is a mandatory step for installation Magisk or SuperSU. It is worth noting that this procedure often results in a complete reset of the device to factory settings.
The unlocking process differs depending on the manufacturer. For devices based on processors MediaTek or Qualcomm may require special utilities such as SP Flash Tool or commands Fastboot. Owners of smartphones Xiaomi need to obtain special permission through the official Mi Unlock utility, linking the account to the device for up to 168 hours.
For brand devices Google Pixel or OnePlus the procedure is simplified as much as possible and is performed through the command line line. After switching the phone to Fastboot mode (usually by pressing the volume button down when turning it on), just enter the unlock command. However, on devices of some US carriers, unlocking may be completely disabled at the software level.

Running this command initiates the data clearing process. The device will reboot and all user files will be deleted. This is done to protect the previous owner's data in case the device is stolen. Therefore, having a backup before this stage is a critical requirement.
⚠️ Attention: Unlocking the bootloader will void the device warranty from most official dealers. Restoring a locked state does not always return the warranty.
What to do if unlocking is prohibited?
Some telecom operators (especially in the USA) programmatically block the ability to unlock the bootloader. In such cases, standard methods will not work, and you will need to search for exploits of processor vulnerabilities, which is extremely risky.
The process of installing superuser rights via ADB
After the bootloader is unlocked and the drivers are installed, you can proceed to directly installing root access. The most modern and safest method involves using the tool Magisk. First you need to download the image boot.imgthat corresponds to your current firmware version. This file can be extracted from the official update or downloaded from the developer forums.
Copy the resulting image to your smartphone and flash it through the app Magisk Manager. Select the “Install” option and specify the file path boot.img. Application create a modified file magisk_patched.imgthat needs to be returned back to the computer. Next, the device is switched to Fastboot.
mode. The final stage is performed through the command line on the computer. Connect your phone, open a terminal in the tools folder ADB and enter the command to flash the modified image. After successfully executing the command and rebooting, the device should gain superuser rights.

An alternative method for older devices may involve using utilities like KingRoot via a PC. In this case, the app automatically detects the model and tries to apply a known exploit. However, the effectiveness of such methods on new versions Android 10-14 is extremely low due to enhanced kernel protection mechanisms.
Checking for root access and access control
After rebooting the device, you need to make sure that the procedure was successful. To do this, you can download the utility Google Play . Running the test will show whether the current user session has superuser privileges. If the result is positive, you will see a corresponding notification and a green indicator. Root Checkerin the application store
Access control for applications is carried out through the interface Magisk Manager or SuperSU. In the settings section you can see a list of requests for root access. It is recommended to set the “Ask” mode for all new applications to control which apps gain deep access to the system.
Some highly secure banking applications and services (Google Pay, banking clients) may refuse to work on rooted devices. To get around this problem in the settings Magisk there is a function “Magisk Hide” or “DenyList”, which hides the fact of having root access from selected applications.
| Characteristics | SuperSU (Outdated) | Magisk (Current) | KingRoot |
|---|---|---|---|
| Installation type | Via Recovery | Via Boot modification | Automatic exploit |
| Support for Android 12+ | No | Yes | Partially |
| Hide root access | Absent | Built-in (Zygisk) | No |
| Security | Medium | High (Systemless) | Low (closed source) |
Magisk is currently the industry standard thanks to its systemless root technology, which does not directly modify the system partition.
Possible problems and methods for solving them
During the rooting process, users often encounter the “Device unauthorized” error in the command line window. This means that the computer has not been authorized on the device. The solution is to unplug the cable, turn off USB debugging, reboot the phone, and re-enable debugging with RSA key confirmation.
Another common problem is the "bootloop", where the phone endlessly reboots at the manufacturer's logo. This happens when flashing an incompatible image boot.img. In this case, you need to enter the mode again Fastboot and flash the original, stock image of the boot partition, which was saved before starting the modifications.
It is also possible that there are no drivers in the Windows Device Manager. If the phone is detected as an “Unknown Device”, try manually updating the driver by specifying the path to the installed folder ADB. In some cases, disabling driver digital signature verification in Windows boot options helps.
⚠️ Attention: Menu interfaces and item names may differ depending on the manufacturer's shell (MIUI, OneUI, ColorOS). Always check the documentation for your specific model before executing commands.
If the fastboot command is not recognized, try running Command Prompt as an administrator or check to see if your antivirus is blocking script execution.
Frequently asked questions (FAQ)
Is it safe to install system updates after receiving Root?
Usually no. Installing an official update “over the air” (OTA) most often leads to the loss of root access or even to “bricking” the device if the system partition has been modified. It is recommended to download full firmware images and install them manually, while saving the modified boot image.
Is it possible to remove root access and return the phone to its original state?
Yes, this is possible. The application Magisk Manager has a “Full Cleanup” function, which removes the root and restores the original boot image. For a full guarantee, it is also worth flashing the device through the manufacturer’s official tool (for example, Odin for Samsung or Mi Flash for Xiaomi).
Does rooting affect the camera’s operation and photo quality?
The mere fact of having superuser rights does not affect the camera. However, installing custom kernels or system modifications may disrupt the operation of image processing algorithms. If you notice a deterioration in quality, try resetting the kernel or rolling back the changes.
Do all rooting methods require an unlocked bootloader?
For modern methods such as Magiskunlocking the bootloader is required. Old exploit methods (as in KingRoot) can theoretically work without unlocking, using system vulnerabilities, but on new versions Android such vulnerabilities are quickly closed, making the method inoperative.
