Obtaining superuser rights to smartphone is a step that opens the door to a world of limitless possibilities, but at the same time imposes serious responsibility on the owner of the device. By default, the operating system Android restricts the user's actions regarding system files and the kernel to prevent accidental breakdowns or infection with malware. However, enthusiasts often require full control to remove pre-installed software, overclock the processor, or deeply customize the interface.
The process of obtaining such privileges has undergone significant changes in recent years: if previously it was enough to launch one application, now the procedure requires unlocking the bootloader and using specialized utilities on the PC. In this guide, we will look in detail at how to enable root access on Android safely, which tools are the standard today, and what consequences you should prepare for before starting the procedure.
What are root access and why you need them?
The term root access comes from Unix-like systems, where "root" means the chief administrator systems. In the context of mobile devices, this is analogous to administrator rights in Windows, but with a much wider range of influence on operating system files. Having received these rights, you cease to be just a user and become the owner of your gadget in the full sense of the word.
Why might an ordinary user need such deep integration? The list of features is truly impressive: from the banal removal of uninstallable applications that manufacturers often build into the firmware, to the installation of specialized modules that change the logic of the camera or sound path. Without root access, many system partitions remain read-only.
However, it is worth understanding that expanding rights also entails expanding risk areas. Malware that gains root access can cause irreparable damage by stealing data or bricking the device. Therefore, the decision to obtain rights must be balanced and informed.
- 🚀 Complete removal of system garbage and bloatware without using ADB.
- 🎨 Deep customization of the interface, fonts and system animations.
- 🔋 Advanced control over energy saving and overclocking processor.
- 🛡️ Installing firewalls for complete control of application network traffic.
⚠️ Attention: Obtaining root access almost always leads to security flags being triggered (for example, Samsung Knox), which can irreversibly deprive you of the guarantee and the ability to use secure banking applications.
Preparation of the device and necessary tools
Before starting active actions, it is necessary to carry out thorough preparation. Modern Android has a multi-level protection system, and an attempt to obtain rights without prior configuration may lead to an error at the first stage. It is critically important to create a complete backup of all data, as the process often involves a complete reset of the device.
You will need a computer with ADB and Fastboot drivers installed, as well as the original USB cable. Do not use cheap "charge only" cables as they will not provide the stable connection needed to transmit commands. Also make sure that the smartphone's battery charge is at least 60-70% to avoid shutting down at a critical moment.
For most modern devices, the use of the utility has become the gold standard. Magisk. This is an open source solution that allows you to obtain root access using a systemless method, which increases the chances of banking applications running and passing SafetyNet tests. You will need to download the latest version of Magisk in APK format and possibly a bootloader image (boot.img) for your specific model and firmware version.
☑️ Pre-rooting checklist
Unlock the bootloader
First and the most difficult step on the path to freedom is unlocking the bootloader. Smartphone manufacturers block this area by default to prevent the installation of unverified software. The procedure varies greatly depending on the brand: some, such as Xiaomi or OnePlus, provide official tools, while others, such as Huawei or US carrier versions, may block this ability completely.
For Xiaomi devices, you must obtain special permission through the Mi Unlock Tool utility. by linking your account to the device and waiting for the required timer (usually from 3 to 7 days). For Pixel and Nexus devices, the command is executed through Fastboot mode with a simple instruction. It is important to understand that this operation will delete all data from the internal storage, so the backup step cannot be ignored.
After successful unlocking, you will see a warning screen every time you turn on the phone, informing you that the device is not certified. This is a normal phenomenon and will only disappear after re-locking the bootloader (which will require reverting to stock firmware).

Issuing these commands in Fastboot mode will initiate the data clearing and unlocking process. On some models, you may need to confirm the action with the volume buttons directly on the smartphone screen.
⚠️ Attention: On Samsung smartphones, unlocking the bootloader physically switches the eFuse electronic fuse. After this, it is impossible to return the device to its original state for Samsung Pay and the protected folder to work, even if you lock the bootloader back.
Installing Magisk and obtaining superuser rights
The most relevant method of obtaining root access today is patching the bootloader image with help Magisk. Unlike older methods that modified the system partition, this method only makes changes to the boot partition, making the process reversible and less noticeable to the security system.
The process begins by extracting a file boot.img from the official firmware for your model. This file must be transferred to your smartphone, launch the Magisk application, select “Install” and specify the path to this file. The application will create a patched version, which will need to be sent to the computer again.
Next, the phone is put into Fastboot mode (or Download Mode for Samsung), and the patched image is written to the download section. After rebooting, you will have a working system with superuser rights. If everything went well, a Magisk icon will appear in the application menu, confirming that you have root access.
| Stage | Action | Risk of error |
|---|---|---|
| 1 | Extracting boot.img | Low |
| 2 | Patching via Magisk | Low |
| 3 | Firmware via Fastboot | High |
| 4 | First boot | Average |
What to do if the phone goes into Bootloop?
If after flashing the firmware the phone reboots cyclically, do not panic. Enter Recovery or Fastboot mode and try to flash the original (not patched) boot.img back. This will return the system to a working state without root access, but with saved data (if the data section has not been touched).
Setting up Magisk Hide and working with banking applications
obtaining root access is only half the battle. Many applications, especially banking and payment systems, have root access and refuse to work. To solve this problem, Magisk has a hiding feature that allows you to bypass security checks.
In new versions of the interface, this feature has been renamed and redesigned as "DenyList". You need to go to Magisk settings, activate this list and select applications that should “think” that there are no root access. Typically these are banking clients, Google Pay and anti-cheat games.
It is also recommended to enable the Zygisk feature, which allows you to run Magisk code in the Zygote process (the main Android process). This provides deeper integration and better compatibility with modules. However, it is worth remembering that developers of banking applications are constantly improving detection methods, so work may require periodic adjustments.
Use the "MagiskHide Props Config" module if the application requires a security certificate of a certain level, which was reset when unlocking the bootloader.
Possible problems and recovery methods
Even if you strictly follow the instructions, unforeseen circumstances may arise. The most common problem is “bootloop”, when the phone endlessly reboots. This often happens when flashing a bootloader image from a different version of Android or for a different device model.
Another common problem is loss of connection to the network or non-working Wi-Fi/Bluetooth after obtaining root access. This indicates damage to the partition with the modem firmware or a driver conflict. In such cases, the only way out is often to completely flash the device through official utilities (Odin for Samsung, Mi Flash for Xiaomi, etc.).
Do not forget about data security. With /root access, any application that you give superuser permission to has full control over the system. Carefully monitor requests from the SuperSU or Magisk application and do not confirm access to suspicious apps.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the version of Android and the manufacturer's shell. Always check the relevant forums (for example, 4PDA or XDA) for your specific model before starting work.
The most reliable way to avoid problems is to use only those files (boot.img) and instructions that are specifically prepared for your exact model and firmware version.
FAQ: Frequently Asked Questions
Will the warranty expire after receiving root access?
In most cases, yes. Unlocking the bootloader and changing the system software is a violation of the warranty terms. Some manufacturers (for example, Xiaomi when using the official method) may formally maintain the hardware warranty, but will refuse warranty service if the failure is related to software. Samsung automatically records the fact of interference through Knox.
Is it possible to update the system over the air (OTA) with root access?
Usually no. The presence of a modified download section blocks the installation of official updates over the air. Trying to update may result in an error or loss of root access. It is recommended to download full firmware images and update manually via Recovery or Fastboot mode, re-patching the image after each update.
Is it safe to use banking applications with root?
This is a risk. Although Magisk allows you to hide your rights, banks are constantly updating their security systems. The application may work today, but after the next update it may stop working. For financial transactions, it is recommended to use a second device without root access or temporarily remove rights before transactions.
How to completely remove root access and return the phone to its original state?
The Magisk application has a “Full uninstallation” function, which automatically restores the original bootloader image. However, to fully return to the factory state and be able to obtain a warranty, it is often necessary to flash the stock firmware via a computer and re-lock the bootloader.
