Obtaining superuser rights, or root accessopens up unlimited possibilities for the smartphone owner to customize and manage the system. This is an analogue of administrator rights in the Windows operating system, allowing you to remove pre-installed applications, change the system kernel and deeply customize the interface. However, along with new functions, the user takes responsibility for the stability of the device.
Many enthusiasts are looking for ways to circumvent the restrictions imposed by manufacturers in order to squeeze maximum performance out of their gadget. This process is not trivial and requires care, since one mistake can turn the phone into a “brick.” In this article, we will analyze in detail modern methods of rooting, the necessary tools and pitfalls that you will encounter.
It is worth immediately noting that in modern realities the concept of “rooting” has evolved. If previously system vulnerabilities were used to install binary files, today modification of the boot image via Magiskhas become the de facto standard. This approach allows you not only to gain access to the system, but also to hide the fact of rooting from banking applications and Google Pay services.
Device preparation and necessary tools
Before taking active steps, you need to make sure that your device is ready to interfere with system partitions. A critical step is to save all important data, as the process often involves a full factory reset. Losing photos, contacts or correspondence can be an unpleasant surprise if you have not made a backup copy in advance.
You will need a computer with ADB and Fastboot drivers installed. This is a basic toolkit for communicating with a smartphone in debugging mode. Without these utilities, it will be impossible to unlock the bootloader on most modern models. Also make sure that the phone's battery is charged at least 60% so that the device does not turn off at the most critical moment of the firmware.
Specialized software is often required to work with system files. A popular choice is Platform Tools from Google, which contains all the necessary executable files. Installation is simple: the archive is unpacked into a convenient folder on drive C, from where control commands will subsequently be entered.
☑️ Preparing for rooting
⚠️ Attention: Unlocking the bootloader on many smartphones (for example, Samsung or Huawei) may trigger the Knox counter or complete blocking some camera functions. Check the manufacturer's policy before starting work.
Unlocking the bootloader
The bootloader is a app that runs before the operating system and verifies the integrity of the signature of the loaded software. By default, it is blocked by the manufacturer to prevent the installation of unverified images. Obtaining root access is impossible without first unlocking this protection mechanism.
The procedure varies depending on the brand of the device. Owners Xiaomi or Motorola often require obtaining a special unlock code through the official website of the manufacturer linked to the account. In the case of pure Android devices, the process is simplified and is performed directly through console commands. After enabling developer mode and allowing OEM unlocking, the device is switched to Fastboot mode. This is usually done by using a combination of the volume and power keys while the phone is turned off. By connecting your smartphone to a PC, you can send a command that will erase all user data and remove the lock. Pixel or pure Android devices, the process is simplified and performed directly through console commands.

- 🔓 Command for unlocking on pure Android:
fastboot flashing unlock - 📱 On Xiaomi devices, a utility is used Mi Unlock Tool, which requires waiting from 3 to 7 days.
- ⚙️ On some Sony and HTC models, the unlock code is generated on the IMEI support site.
It is important to understand that after unlocking the bootloader, the device warranty may be voided. Manufacturers consider this action as a violation of operating conditions, since the user receives full control over the hardware. You can return the bootloader to its original state with the command fastboot flashing lock, but this does not always restore the warranty status.
What is OEM unlocking?
This is a switch in the “For Developers” menu that allows the bootloader to accept commands to change memory partitions. Without enabling this option, fastboot commands will be rejected by the device.
Installing Magisk and obtaining superuser rights
Today Magisk is the most secure and functional way to gain root access. Unlike older methods that modified the system partition, Magisk works with the boot image, leaving the system partition untouched. This allows you to check the system integrity (SafetyNet/Play Integrity).
The process begins with obtaining the official firmware image (stock firmware) specifically for your model and version of Android. A file is extracted from this archive boot.img (or init_boot.img on new devices with A/B partitions). This file is transferred to the smartphone, where it is processed by the Magisk Manager application.
After patching the file, the application will create a new image with a name like magisk_patched.img. It must be returned to the computer and flashed into the bootloader partition via Fastboot mode. The command for this looks standard, but requires specifying the path to the file.
fastboot flash boot magisk_patched.imgAfter successful firmware and first boot, you will see a new application in the menu, which will confirm that you have superuser rights. Now you can install modules, change system settings and control application access to Root functions. It is worth noting that on devices with dynamic partitions the process may differ slightly, requiring firmware to be inserted into slots boot_a and boot_b.
If after flashing the phone the phone goes into a cyclic reboot (bootloop), hold down the power and volume buttons to enter recovery mode, and try clearing the cache or restoring the original boot.img.
Access control and system security
Having root access makes the user responsible for data security. Any application that requests superuser rights gets unrestricted access to the entire file system. Uncontrolled granting of permissions can lead to the leakage of confidential information or the installation of malware.
The Magisk Manager application acts as an access manager. The first time you launch a protected application, you will see a pop-up window asking for confirmation. You can choose to Grant, Deny, or Grant Once Only. It is recommended to carefully read requests and not give rights to dubious utilities.
One of the key functions of modern rooting is the ability to hide these rights. Banking apps and games with anti-cheat often block work on rooted devices. In the Magisk settings, you can activate “Zygisk” and add the desired applications to the exclusion list (DenyList) so that they “do not see” the presence of superuser rights.
| Parameter | Standard Android | Root access (Magisk) |
|---|---|---|
| Access to system files | Read only | Read and write |
| Delete system applications | Impossible | Possible |
| Banking applications work | Stable | Requires hiding settings |
| Installation of custom kernels | Blocked | Allowed |
| Device warranty | Saved | Most often voided |
⚠️ Attention: Never provide root access to applications downloaded from unverified sources. Malicious code with superuser rights can completely destroy your operating system.
Useful features after obtaining Root
Why are these complications needed at all? The list of benefits is extensive. You get the opportunity to remove unnecessary bloatware pre-installed operator or manufacturer applications that take up space and consume resources in the background. This can significantly extend battery life.
It also provides access to powerful automation tools, such as Tasker in conjunction with plugins that require deep access to the system. You can set up scripts that will change the processor frequency, turn on airplane mode at a certain time, or take screenshots on a schedule without system notifications.
For advanced users, installing custom kernels (Kernels) is available. This allows you to overclock the processor for games or, conversely, greatly reduce frequencies to save energy. Voltage and thermal control becomes available through special applications like Kernel Adiutor.
Another important function is creating full system backups via Titanium Backup or its modern analogues. Unlike standard Google tools, such utilities save not only data, but also application states, system settings and authorization keys, allowing you to restore your phone exactly up to the minute after a reset.
Possible problems and ways to solve them
Rooting is a risky process, and failures happen even among experienced users. The most common problem is the “bootlap”, when the phone endlessly reboots at the logo. This usually happens when flashing an incompatible kernel image or a damaged bootloader partition.
To solve such problems, you must be able to enter Recovery mode. If a custom recovery is installed (for example, TWRP), you can try clearing the cache and Dalvik cache, as well as restoring a previously made backup (Nandroid backup). If the recovery is stock, often only flashing the original firmware via a computer helps.
Sometimes after updating the operating system over the air (OTA), root access is lost. This is normal because the updated system partition will overwrite the modified boot image. In this case, the procedure for patching a new boot image must be repeated again, having first saved the image from the new firmware.
⚠️ Attention: Menu interfaces and item names may differ depending on the Android version and the manufacturer's shell. Always check the current guides for your specific device model before executing commands.
The most reliable way to restore your phone after unsuccessful rooting is to completely flash the stock image via Fastboot mode or the manufacturer’s specialized software (Odin, MiFlash).
Frequently asked questions (FAQ)
Are warranty obligations reset after receiving root?
In most cases, yes. Unlocking the bootloader and modifying the software is a violation of the user agreement. Although physical traces of tampering can be removed, service centers have tools to check the status of the bootloader and security counters (for example, Knox).
Is it possible to get root without unlocking the bootloader?
Theoretically, yes, using exploits of vulnerabilities (for example, through applications like KingRoot), but on modern versions of Android (10, 11, 12 and above), this method practically does not work and is extremely unsafe. Such applications often contain spyware. The safe method requires mandatory unlocking of BL.
Will Google Pay and banking applications work?
By default, they will not work, as they see a violation of the integrity of the system. However, using Magisk Hide (or setting DenyList in new versions) and modules like Play Integrity Fix, you can successfully hide the presence of root access and restore functionality to payment services.
What to do if the phone stops turning on after the firmware?
Try to enter Fastboot mode (usually Volume Down + Power) and connect the phone to PC. If the computer sees the device, you can flash the original boot.img. If the phone does not respond at all (black screen), the service center may need to intervene to reflash it through test points.
Will a factory reset remove root access?
No. Wipe Data only affects the user partition. root access is located in the system or boot partition. To remove root, you need to flash the original boot image or use the “Full removal” function in the Magisk application, if available.
