Obtaining superuser rights, or so-called root accessopens up opportunities for the smartphone owner that were initially hidden by the system developers. It's not just a way to install a custom theme or remove pre-installed junk, it's complete control over your device's file system. Many users wonder how to root on Android in order to expand the functionality of the gadget, but are often stopped by the complexity of the procedure and the fear of turning the phone into a “brick.”
The rooting process has changed dramatically in recent years. If earlier there were one-click apps, then modern versions Android require unlocking the bootloader and working with console utilities. Security has become a priority for Google, so standard bypass methods no longer work on the latest firmware. You have to go from enabling USB debugging to modifying the system image boot.img.
It is important to understand that each smartphone model is unique. What worked perfectly for Xiaomimay not be applicable to Samsung or Pixel. In this article, we will look at universal principles, current tools, and pitfalls that you will encounter when trying to gain privileged access rights to the system kernel.
Device preparation and risk assessment
Before taking active steps, you need to understand the consequences. Obtaining root access is an irreversible process in terms of warranty service. Smartphone manufacturers consider tampering with system partitions as a violation of operating conditions. The counter KNX or similar protection mechanisms are triggered, after which the official service may refuse free repairs.
The first step should be to create a complete backup copy of all important data. Even if the procedure is successful, files may be damaged or lost during the bootloader unlocking process, which is often accompanied by a full factory reset. Use cloud storage or connect your device to your computer to copy photos and documents.
⚠️ Warning: Unlocking the bootloader will void your device's warranty in most cases. This also makes it impossible to use banking applications and contactless payment services without additional manipulations.
You need to accurately determine the processor model and firmware version. To do this, go to your phone settings and find the About the phonesection. Write down the build number and kernel version Android. This information is critical when finding suitable files for flashing. An error in selecting a file may cause the phone to stop turning on.
Charge the device's battery to at least 70-80%. The process of flashing or modifying system files is energy-consuming. A sudden power outage while writing data to the partition system or boot is guaranteed to disable the device, and it will be extremely difficult even for an experienced specialist to restore it.
Unlocking the bootloader
The key step on the path to root access is unlocking the bootloader. By default, this component blocks any unsigned code from running, which prevents the installation of modified kernel images. Without an open bootloader, obtaining superuser rights on modern devices is impossible.
The procedure differs for different brands. For devices Xiaomi requires the official Mi Unlock utility and a wait of 7 to 15 days after linking the account. Owners Pixel i OnePlus can execute the command via Fastboot almost instantly. Smartphones Samsung require switching to Download Mode and confirming the action with the volume buttons.
To unlock, you will need a computer with ADB and Fastboot drivers installed. Connect your phone with a cable while holding down a specific key combination (usually the power button and volume down) to get into bootloader mode. In the command line of your computer, enter the command:
fastboot flashing unlockOr an alternative option for older devices:
fastboot oem unlockA warning about data loss will appear on the smartphone screen. Confirm the action using the navigation buttons. The device will reboot and reset all user data. This is a necessary security step to ensure that the new owner (or you in a new environment) will not have access to the encrypted data of the previous configuration.
What to do if the command fails?
If the console displays a "device not found" or "waiting for device" error, check your installed drivers. Try a different USB cable or switch to another USB 2.0 port, as USB 3.0 ports sometimes cause conflicts when working with Fastboot.
Installing custom recovery (TWRP)
The standard recovery menu (Stock Recovery) has limited functionality and does not allow installing third-party ones zip archives or modify system partitions. To fully work with root access, you need to install a custom recovery, the most popular of which is TWRP (Team Win Recovery Project).
The recovery image file must be strictly compatible with your device model. Download it only from official sources or trusted forums, such as 4PDA or XDA Developers. Using an image from another model will cause the device to “brick” due to incompatibility of memory addresses and drivers.
The installation process is carried out through Fastboot mode. Connect your phone to the PC and run the command:
fastboot flash recovery twrp_image_name.imgHowever, on some devices with dynamic partitions or protection AVB (Android Verified Boot), the standard command may not work or the recovery will be replaced by the stock one at the first boot. In such cases, temporary loading of the image without firmware is used:
fastboot boot twrp_image_name.img| Action | Command / Method | Risk |
|---|---|---|
| Entering Fastboot | ADB reboot bootloader | Low |
| Unlock BL | fastboot flashing unlock | Data loss |
| Installing TWRP | fastboot flash recovery | Medium |
| Running TWRP | fastboot boot recovery | Low |
After successful installation or download, you must immediately put the device into recovery mode to avoid automatically returning to stock recovery. This is usually done by holding down the volume and power buttons immediately after rebooting from Fastboot.
Installing Magisk and obtaining root access
Today Magisk is the de facto standard for obtaining root access. Unlike the outdated SuperSU, Magisk uses a system of system-less modifications, which allows you to hide the fact of having root access from banking applications and games.
To install, you will need an image file magisk.apk, which you need to rename to magisk.zip (or simply move it to memory phone if TWRP supports apk installation). Boot into the TWRP menu, select Install and specify the downloaded archive. Swipe to confirm the firmware.
- 🔧 After installation, Magisk will create a partition
magisk.imgin the device memory where all changes will be mounted. - 📱 When the system first boots, a notification from the Magisk application will appear asking you to complete the setup - agree and wait for the reboot.
- 🛡️ In Magisk settings, you must enable the "Zygisk" function for full compatibility with modern applications.
There is an alternative installation method through patching the image boot.img. If you do not have access to custom recovery, you can extract the firmware file, open the Magisk application on your phone, select "Install" -> "Select and flash file" and specify the original boot.img. The resulting patched file is then flashed via Fastboot with the command fastboot flash boot patched_boot.img.
☑️ Magisk installation checklist
Setting up hiding Root for banking applications
The most common problem after receiving rights - refusal of banking applications, Google Pay and some games to work. They use the service Google SafetyNet or new Play Integrity API to check the integrity of the system. Detection of a modified bootloader or superuser rights leads to blocking of functionality.
In the Magisk application, go to the settings and activate the switch Enforce DenyList (Forced exclusion list). Then go to the list itself and mark all applications that should “think” that there are no root access: banks, stores, games with anti-cheat. This will force Magisk to hide access to these applications.
⚠️ Attention: Banking application interfaces and detection methods are constantly updated. What worked yesterday may no longer work after you update your banking app. Keep an eye on updates to hiding modules.
Additionally, you may need to install a module Universal SafetyNet Fix or its analogues if the standard settings are not enough. These modules replace device identifiers and bootloader status in system responses to Google service requests. Be prepared that the process of setting up hiding may take time and require selecting specific versions of modules.
If the bank application still does not work, try clearing its cache and data after setting up DenyList in Magisk. Sometimes old data retains information about the presence of root access.
Capabilities and access control
After successful installation, you get unlimited access to the system. Now you can change the processor frequency, remove system applications that cannot be removed by normal means, and install global interface modifications. The Superuser rights manager in the Magisk application allows you to flexibly configure access for each application.
When any application requests root access, a notification pops up on the screen. You can choose to grant access forever, for one time only, or deny the request. It is recommended to reject all requests by default and grant rights only to those utilities that you trust 100%.
Using superuser rights opens the door to powerful automation tools, such as Tasker in conjunction with plugins, or specialized backup utilities like Swift Backupthat can save application data along with their settings. This is a level of control not available to the average user.

root access give full control, but impose responsibility: one incorrect action in a system file may require a complete flashing of the device.
Frequent problems and ways to solve them
During the rooting process, users often encounter a cyclic reboot (bootloop). If your phone is stuck on the logo, first try booting into Recovery mode and clearing the cache (Wipe Cache/Dalvik). If this does not help, you may need to restore the original image boot.img via Fastboot.
Another common problem is loss of network or non-working Wi-Fi after installing a custom kernel or recovery. This indicates incompatibility between the radio module and software. In such cases, flashing the stock firmware through the manufacturer's official utilities, such as for Samsung or MediaTek, helps. Don't forget that over-the-air (OTA) system updates are usually not installed automatically on a rooted device. Attempting to update may result in loss of root access or system crash. Before updating, it is recommended to make a full backup, temporarily return the stock bootloader and recovery, update, and then repeat the rooting procedure.

Is it safe to obtain root access on modern Android?
Security depends on your actions. The process itself does not contain viruses, but it opens the door to malware if you grant permissions to dubious applications. With proper use and configuration of Magisk Hide, the level of security remains high.
Will my data be reset when receiving Root?
Yes, at the stage of unlocking the bootloader, all data will be deleted. This is an Android security requirement. Be sure to make a backup copy before starting the procedure. Further steps (installing TWRP, Magisk) do not affect the data.
Is it possible to return the phone to its original state?
Yes, you can lock the bootloader back and flash the stock firmware. However, the Knox counter (on Samsung) or similar flags may remain toggled forever, which will be visible in the service menu.
Does Google Pay work after rooting?
By default, no. But with the help of Magisk and hiding modules (DenyList, Zygisk, SafetyNet Fix), you can bypass the system integrity check and return contactless payment to work in most cases.
Do you need a computer to obtain root access?
In 95% of cases, yes. Unlocking the bootloader and installing the initial recovery requires connecting to a PC with ADB/Fastboot drivers installed. There are methods without a PC, but they are rare and less reliable.
