Xiaomi and Redmi smartphone owners often face limitations of MIUI or HyperOS operating systems that prevent them from fully managing their device. The phone’s standard mode of operation only provides basic functions to the user, hiding deep system settings, and this is where Root comes into the scene, giving unlimited administrator rights.
Obtaining these rights opens the door to installing customized modules, removing system debris, and fine-tuning the processor. However, it's not just an "on" button, but a complex process that requires an understanding of the Android architecture. Before you start, you need to realize that you take responsibility for the stability of the gadget.
In this article, we will take a closer look at the theoretical framework, assess the risks, and look at the current methods of obtaining super-user privilege, explain why the old methods no longer work and what tools are relevant for the Chinese brand devices this year.
Root rights and Android security architecture
The term Root comes from the Linux-like operating system that runs Android. In Linux, "root" is the system's chief administrator, with absolute control over all files and processes. On conventional smartphones, the user operates in a limited-enabled "guest" mode to prevent accidental or malicious damage to critical memory partitions.
Xiaomi, like other manufacturers, implements protection. Bootloader is blocked by default, which physically prohibits changes to the system partition without official unlocking, creating a barrier that can not be overcome by simply installing an application from the Play Market.
Obtaining superuser rights effectively means unlocking the bootloader and embedding a binary file that intercepts application requests to the system. If a program requests access to a system file, that intermediary file (usually Magisk) asks you for permission and, if agreed, grants access on behalf of the administrator.
- 🔓 Full control of the file system and the ability to edit system configs.
- 🛡️ Bypassing embedded constraints MIUI background.
- ⚙️ Possibility of installing custom cores for acceleration or energy saving.
- 🗑️ Removal of undeleteable standard applications taking up space.
⚠️ Attention: Interference with the structure of the bootloader and system files automatically voids the manufacturer's warranty. Xiaomi service centers can refuse free repairs after detecting traces of software modification.
Risk analysis: Is the game worth the candle?
The decision to grant superuser rights must be considered, and on the one hand, you get a powerful tool, on the other hand, you lose a number of security and stability features, and banking applications become a major stumbling block as they actively scan the environment for modifications.
Modern versions of Magisk can hide root rights, but this is an eternal arms race, banks are updating detection methods, and developers of magic modules are looking for new workarounds, and the risk of “bricking” the device if a user’s actions are mistaken should be considered.
Another important aspect is the operation of the Widevine L1 function. On many Xiaomi devices, after unlocking the bootloader, the DRM certification drops to the L3 level, which limits the playback of high-resolution content (HD/4K) in streaming services like Netflix.
- 📉 Possible loss of Widevine certification L1 Decreasing video quality.
- 💸 Denial of warranty service when applying to the service.
- 🔒 Risk of data leakage if malware gets administrator rights.
- 🔄 Difficulties with updating the system “by air» (OTA).
💡
Before any manipulations, be sure to create a full backup of important data on an external medium or in the cloud, as unlocking the bootloader completely clears the phone’s internal memory.
Preparation of the device: unlocking the loader
Without an unlocked Bootloader, getting root rights to Xiaomi is impossible.This is the first and mandatory step, which takes time and requires a Mi Account.The process is not instantaneous: after applying in the Mi Unlock Tool application, you often have to wait from 7 to 168 hours.
To start, you need to turn on Developer Mode. Go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). After that, a new section will appear in the menu Additional or Advanced Settings, where you need to select For Developers.
In the developer menu, activate the items Factory unlocking and debugging by USB. It is also important to link an account in the special item “Mi Unlock Status”, adding SIM-Card and mobile Internet (Wi-Fi must be temporarily disabled).
☑️ Checklist of preparations for unlocking
After waiting for the server to set a deadline, you can start unlocking the device itself. Turn off the phone and press the Volume Down + Power buttons until the Fastboot logo appears. Connect the device to the PC and launch the Mi Unlock Tool.
fastboot flashing unlockThis command, executed via ADB, or the Unlock button in the program's GUI, will start the reset process. The phone will reboot and completely clear user data. This is a security measure to prevent the new owner from accessing the previous one's data.
| Phase | Action. | Risk of error |
|---|---|---|
| 1 | Account binding | Low (network error) |
| 2 | Waiting for a timer | Absent. |
| 3 | Fastboot launch | Low (wrong buttons) |
| 4 | Unlock command. | Medium (cable interruption) |
Installation Magisk: a modern standard
Today, topjohnwu's Magisk is the standard for root rights. Unlike the old methods (SuperSU), Magisk works systemlessly without physically changing the /system partition.
The installation process requires a firmware file (fastboot or recovery) that matches the version installed on your Xiaomi. 4PDA. File is extracted from the firmware archive boot.img.
Install the Magisk app on your phone, open it, and select "Install." As a method, select "Select and patch a file." Find the previously extracted file. boot.img. The program will create a new file with a prefix magisk_patched.
What if the phone doesn’t see a patched image?
Once you have a patched image, copy it to your computer. Put your smartphone in Fastboot mode and connect it to your PC. From the command line in the tool folder of the platform, type in the firmware command:
fastboot flash boot magisk_patched_[hash].imgOnce you have a successful firmware, type in the command fastboot reboot. If it goes well, you will see the Magisk logo when you download it, and the version number will appear in the application in the "Magisk" bar, which means that Root access is active.
Rights management and modules
Once installed successfully, you can see a world of modules. Magisk allows you to embed code into your system processes on the fly. For example, the AdAway module can edit the hosts file to block ads throughout the system, not just in the browser.
It is important to set up root rights hiding correctly. In Magisk's gear settings, turn on "Zygisk" and "Accept the Exclusion List." Then, in the "Set up the Exclusion List" (formerly MagiskHide) section, tick all banking apps, Google Pay, and anti-cheat games.
Do not overuse the number of modules. Each script that runs consumes RAM and can slow down the system load, remove unused modules and monitor the logs if the device begins to behave unstable.

- 🔋 Cooler: Control of processor trottling for games.
- 🎨 Substratum: a deep interface change without a custom theme.
- 📸 GCam Loader: Forced to run Google Camera on unsupported devices.
⚠️ Warning: Installing modules that change system fonts or critical libraries can cause the phone to stop turning on. Always have a spare on hand boot.img stock-stack.
💡
Magisk works on the principle of systemless, which means no direct changes to the system partition, which is critical for passing security checks in applications.
Possible problems and methods of solving them
The most common problem after unlocking is Bootloop, when the phone is constantly rebooted. This happens if an incompatible image was stitched or the module conflicts with the Android version. boot.img.
Users also often experience a loss of broadband or NFC after manipulation, usually by flashing the modem or resetting the network settings.
If the sound or camera is missing, check if the drivers in the background that conflict with the installed modules have updated. Dalvik/ART via Recovery mode (TWRP).
