Obtaining superuser rights on Xiaomi devices is a step that turns a standard smartphone into a powerful tool for enthusiasts: the owner of Redmi or Poco gets full access to the file system, which allows you to change parameters that are not available in the standard MIUI or HyperOS interface. This opens the door to total customization, removal of system debris and deep optimization of battery life.
However, before making modifications, it is important to understand the responsibility: Getting root rights permanently removes the warranty from the software part of the device and can lead to its transformation into a “brick” if you do not work. In this article, we will examine in detail the functionality that opens up after unlocking the bootloader and installing administrator rights, and assess the real benefits and risks.
Many users are looking for ways to circumvent manufacturer-imposed restrictions, and root access is the only legal (from the user's perspective) way to do that. You will no longer be dependent on vendor update schedules or limitations imposed on background processes. Let's look at specific use cases.
Removal of system advertising and embedded applications
The most common reason users are seeking root rights to Xiaomi is to fight intrusive advertising. Although recent versions of MIUI firmware allow some of the ads to be disabled through settings, they still pop up in system applications. With administrator rights, you can completely cut the ad modules from the system partition.
And the standard suite of applications often contains software that can't be removed in the normal way, like Chinese firmware or pre-installed Google services that aren't used in your area, and using tools like System App Remover or Titanium Backup, you clear memory and free up the workspace.
- 🗑️ Complete removal of msa (MIUI System Ads and other advertising demons.
- 📱 Irreversible removal of system applications: calculator, gallery, Mi browser.
- 🛡️ Blocking ads at the level of host files in all applications and browsers.
- 🚀 Freeing internal memory from undisposable garbage.
It is important to understand that removing critical system components can lead to unstable interface performance, for example, removing a standard download manager can disrupt file downloads in other applications.

Processor Overclocking and Energy Saving Management
One of the most powerful root access capabilities is working with the device's nuclear parameters. Xiaomi's standard power saving profiles are often too aggressive, leading to slowdowns, or vice versa, inefficient, causing a quick discharge. With superuser rights, you get direct access to the power controller and CPU/GPU frequencies.
Using core management applications such as KSU KernelSU or Kernel Adiutor, you can change processor frequencies, voltages, and task scheduler algorithms, which allows you to either maximize performance in games or significantly extend battery life in standby mode.
And then you can also control the temperature limits, and you can prevent the system from dropping the frequencies when it heats up to a certain threshold, which is important for gamers, although it requires caution to avoid overheating.
- ⚡ Clock speed acceleration CPU and GPU boost FPS play.
- 🔋 Undervoltage (voltage reduction) to reduce heat and energy consumption.
- 🌡️ Setting up the thresholds of trottling and the operation of fans (if provided by the design).
- 📉 Fine tuning of the cores: disconnecting energy-consuming cores in the background.
💡
Before changing frequencies or voltages, be sure to back up the current kernel settings. Wrong values can lead to a cyclic bootloop.
System modification and installation of modules
Having root rights opens up access to the Magisk framework or its analogues, and it's not just a rights tool, it's a whole platform for modular system modification without changing the systemless root, which allows you to maintain the integrity of the checksums, which is important for some banking applications.
With modules, you can implement features that are not even available in global firmware, such as adding support for high-resolution audio codecs, implementing a system ad blocker, or modifying fonts and icons at a deep level.
| Type of module | Functional | Impact on the system |
|---|---|---|
| Audio Mods | Sound Improvement, Dolby Atmos, Viper4Android | High (replacement of drivers) |
| UI Tweaks | Changes in status bar, fonts, animations | Average (change in resources) |
| Privacy Tools | Hiding root, replacing device data | Low (works in the runtime) |
| Performance | Memory optimization, CPU management | High (affects the core) |
The modular system makes it easy to roll back changes. If a module caused a crash, it can be removed via Safe Mode or Magisk console, bringing the phone back to life without flashing it back.
Full control of the file system
Without root access, the user is restricted from accessing /data and /system folders, and once you have superuser rights, you become the full owner of the device, which allows you to transfer the application cache to the memory card, edit the system configs, and change the network settings.
This is especially useful for working with messenger databases, system logs and configuration files. You can manually edit hosts files to block trackers or change TCP/IP settings to speed up the Internet.
It also makes it possible to clone applications at the system level, create full backups (backups) of any data, including Wi-Fi passwords and progress in games, with subsequent recovery on another device.
- 📂 Direct access and edit files in the root directories of Android.
- 💾 Create a complete system image (Nandroid backup) before experiments.
- 🔒 Edit permissions and permissions files for any process.
- 🔄 Forced transfer of application data to external SD-map.
💡
A root-access file manager (such as Solid Explorer or MT Manager) becomes your primary smartphone management tool.
Risks and consequences of obtaining Root rights
Despite the vast possibilities, serious drawbacks cannot be ignored. The first and most obvious is SafetyNet and Play Integrity. Google is actively fighting modified devices. Banking applications, Google Pay (Wallet), Netflix (in HD quality) and corporate customers can refuse to work, seeing a violation of the integrity of the system.
The second risk is data security: Any application you give root rights to gets absolute control of your phone, and malware with those rights can steal all passwords, intercept SMS and track location without restrictions.
⚠️ Warning: Setting superuser rights makes your device vulnerable. Never root applications from unknown sources and always check the signatures of the modules you install.
The third aspect is stability: errors in editing system files can lead to loss of data or inability to boot the OS. Recovery often requires an unlocked bootloader and the original firmware image.
- 🚫 Blocking the work of banking applications and NFC-Payment without complex manipulation.
- 📉 Loss of warranty from Xiaomi’s official service center.
- 🐛 Possibility of bugs that were not in the stock firmware.
- 🔐 Risk of personal data leakage when installing malicious modules.
