Modern Xiaomi, Redmi and POCO smartphones offer users huge customization opportunities, but sometimes these opportunities turn into serious problems. Device owners often face the need to disable previously obtained superuser rights to return the gadget to factory condition. This can be caused by the desire to pass SafetyNet check in banking applications, the need to hand over the device as a guarantee, or simply the desire to get rid of the instability of the system caused by third-party modifications.
The process of removing root access on Android is based on understanding exactly how these rights were obtained. If you used automated programs like KingRoot or 360 SuperRoot, the rollback process can be simple. However, if you are talking about manually installing Magisk or changing the system partition through TWRP, the procedure will require deeper file system intervention and possibly firmware reflashing. It is important to realize that simply removing the application manager is not enough, since the system files remain changed.
In this article, we will discuss in detail all known methods of closing access to the kernel of the system on Xiaomi devices. You will learn how to properly use the built-in functions of rights managers, how to perform a full reset via Fastboot and what risks exist when trying to hide the fact of a firmware modification.
Why you should remove the rights of the superuser
The main reason users are looking for a way to shut down root access to Android Xiaomi is the inability to run mission-critical applications. Banking programs such as SberBank Online, Tinkoff or Mir Pay, as well as Google Pay services, use SafetyNet/Play Integrity, which blocks work on modified devices.
In addition, modification of system files often leads to unstable operation of the MIUI or HyperOS operating system. This can manifest itself in accidental reboots, rapid battery discharge due to background processes or errors in the operation of communication modules. If you plan to sell a device, the presence of root rights will significantly reduce its cost and customer confidence, as this indicates a deep interference with the software part.
It is also important to remember that the company's policy is that software modifications are grounds for refusing free repairs. Even if the failure is not related to the software (for example, a charging connector), the service center (specialists) can refuse service if they find an unlocked bootloader or traces of root rights.
- 🔒 Blocking the work of banking applications and NFC-Payment due to security breaches.
- ⚡ Eliminating system errors, freezes and autonomy problems caused by modifications.
- 🛡️ Restoration of warranty status of official service device.
- 🧹 Complete cleaning of the system from traces of third-party interference before sale.
⚠️ Note: If you unlocked the bootloader to obtain rights, simply removing the root files will not be enough.To fully return to factory condition, you often need to re-lock the bootloader, which is only possible on stock firmware.
Checking the current status of access rights
Before taking decisive action, you need to determine exactly the current state of the system. Not always the presence of the application "SuperSU" or "Magisk" means that the rights are active and work correctly. On modern versions of Android, especially in the shells of Xiaomi, rights can be deactivated at the kernel level, even if the rights manager is present in the list of applications.
For accurate diagnosis, it is best to use specialized utilities such as Root Checker or the built-in information in the Magisk manager. Launch the application and press the check button. If the system responds that root access is missing but you see traces of modifications, it may be that the rights have been blocked by a security update or developer settings.
Also, check the bootloader status. Go to the settings, select About Phone, and click on the MIUI version several times to open the extended menu. Find "Truckloader Status." If it says "Unlocked," this means that the system's security is weakened, and you may need to lock it through Fastboot to completely close access.
fastboot oem device-infoThis command, executed in Fastboot mode via your computer, will show detailed information about the device status, including unlock status and boot verification. If you are not familiar with the ADB command line, you should limit yourself to software methods of checking through the Android interface.
How to hide root without removing it?
Removal methods through the application manager
The easiest and safest way to close root access on Xiaomi is for those who have set rights through the popular Magisk tool. Built-in delete allows you to roll back all changes made to the system partition and return the original files. This method is suitable if the device bootloader is still unlocked, but you want to remove traces of the modification.
Open the Magisk app on your smartphone. On the home screen, you'll see a button that says "Uninstall." Click on it and the system will offer two options. The first option, "Complete Uninstall," will automatically restore the original boot image and delete all the manager files. The second option, "Restore Images," is useful if you've updated the OTA firmware and want to save, but in our case we need the first option.
Once confirmed, the device will automatically restart. The process can take several minutes, during which the screen may go out and turn on. Do not interrupt the power at this point. Once downloaded, you will find that the Magisk application has disappeared, and the superuser rights are no longer requested by any program.
☑️ Checklist of removal via Magisk
If you've used older methods, like SuperSU, the procedure is similar. Go to the application settings (Settings) and find "Full Uninstall." The system will warn you that this action is irreversible without re-routing. Confirm the action, and the phone will reset the system files to factory values.
⚠️ Note: If after deleting the rights manager, the phone goes into an endless bootloop, this means that the system files have been corrupted or deleted incorrectly.
Full reset via Fastboot and Mi Flash
In cases where standard deletion does not help, or if you want to guarantee to close all loopholes and return the device to the state of "out of the box", you will need to use a PC and the Mi Flash Tool utility. This method completely erases all data on the phone, so be sure to back up important photos and documents.
First, you need to download the official firmware for your model. Importantly, to completely clean and close root, you need to choose the firmware type "Fastboot" (has the extension.tgz), not "Recovery." Also pay attention to the firmware region - it should match the region of your device, or you should be ready to change the region, which may require an unlocked bootloader.
Unpack the firmware archive to the root of the C disk so that the path does not contain Cyrillic or spaces. Put your smartphone into Fastboot mode, holding both the power and volume buttons. Connect the device to your computer with a USB cable. In Mi Flash, select the path to the firmware folder and be sure to select Clear All mode at the bottom of the window.
| Firmware mode | Data retention | Root removal | BL lockdown |
|---|---|---|---|
| Update (Update) | Yes. | No (partially) | No. |
| Clean All (Clean All) | No. | Yes. | No. |
| Clean All + Lock | No. | Yes. | Yes |
Clear All + Lock not only deletes all data and root rights, but also blocks the bootloader. You can only use lock mode on the full-stock firmware of the corresponding region. If you try to block the bootloader on a custom build or firmware of another region, the device can turn into a brick with a Verified Boot error.
Press Flash and wait for the process to be completed. The green "Success" signifies successful completion. The phone automatically reboots, and you get a clean system without any trace of previous intervention.
💡
Before you install the battery, make sure that the battery is at least 50% and USB-Interrupting the process of writing data into memory can lead to irreversible failure of the device.
Locking the loader and returning the guarantee
Root closure is often confused with Bootloader locking. These are different but related concepts. Root gives permission to modify files, and an unlocked bootloader allows these changes to be made. To completely close access and return the device to the state as close to warranty as possible, the bootloader must be blocked.
This can only be done via Fastboot if the device has the original global or Chinese firmware installed (without modifications). The command fastboot oem lock or use of the "Clean All + Lock" mode in the Mi Flash Tool initiates the locking process. The device will warn that all data will be deleted, and after the restart the bootloader will be closed.
However, having a locked bootloader doesn’t always mean restoring warranty. Xiaomi service centers use special diagnostic tools that show the unlock counter (Counter). If the meter was incremented, the fact of interference in the system remains in the device’s logs forever, even if you closed all the holes.
- 🔒 Blocking the loader is possible only on the stock firmware.
- 📉 The unlock counter in NVRAM not discharged by conventional methods.
- ⚠️ Attempt to block BL On a modified system, you will get bootloop.
- 🌍 The firmware region must strictly correspond to the region of the device.
If your goal is to run banking applications exclusively, you don't have to block the bootloader, but you just need to remove root rights using the methods described above and, if necessary, reflash the device in Clear All mode without locking.
⚠️ Note: Do not attempt to block the bootloader if you have changed the region of the device (for example, from China to Global) by software methods.This can lead to the inability to boot the system and require difficult recovery through the Internet. EDL-regime.
💡
Complete removal of root rights and locking the bootloader return the software part of the phone to its original state, but do not erase the physical trace of the fact of unlocking in the device’s memory.
