Xiaomi Mi8 has long been a flagship smartphone that attracts the attention of enthusiasts and developers due to its performance and openness. However, after obtaining extended access rights, many users face the need to return the device to its original state, this may be due to the sale of the gadget, the requirement of banking applications or the desire to obtain an official guarantee from the service center.
The process of removing superuser rights is not always reduced to simply removing an application. Deep changes in the system section require careful attention and understanding of the structure of Android. In this article, we will discuss in detail all the methods, from software solutions to complete firmware, relevant to the Mi8 model.
Before taking action, you need to be aware of the risks. Any interference with system files carries a potential threat of data loss or device malfunction. Removing root rights through resetting does not guarantee that the system partition is completely cleaned of the modified bootloader. It is therefore important to choose the right method that suits your current situation and the type of modifications you have installed.
Why it is necessary to abandon Root rights
The main reason for returning to the stock system is often the inability to use popular services. Banking applications such as Sberbank Online or Google Pay use SafetyNet security mechanisms that block work on modified devices. Even if the application is launched, contactless payment functions may not be available.
Another important factor is the stability of the operating system: Third-party modules embedded in the systemless partition or directly into system files can cause conflicts, leading to sudden reboots or rapid battery discharge.
Also worth considering is the issue of personal data security: having open access to the root folder makes the device more vulnerable to malware, and attackers can use these breaches to steal sensitive information if a user accidentally installs an infected application.
Xiaomi Mi8 Preparation for System Recovery
The first and most critical step is to save all important information. The process of detachment of administrator rights often involves a complete cleanup of internal memory. Make sure that your contacts, photos and documents are copied to the Mi Cloud cloud server or to your computer.
You need to prepare the tools for the job in advance. USB-cable, preferably original, and installed drivers ADB Without a reliable connection, the procedure can be interrupted at the most inopportune moment.
Also check the battery level. To safely carry out the procedures, the battery charge should be at least 60-70%.A sudden power outage while recording system partitions can lead to the smartphone turning into a โbrickโ.

Method of removing Root through Magisk application
If your Xiaomi Mi8 rights were obtained through the popular Magisk manager, the deletion process is as simple as possible.This method is good because it automatically restores the original system files that were changed during rooting.
Open the Magisk app on your smartphone screen. In the main menu, find a button that says "Uninstall" and clicks on it, the system will offer two options: "Complete Uninstall" and "Restore Images".
Select the option of complete deletion. The system will warn you that all data will be deleted and the device will restart. Confirm the action, and the automatic cleaning process will begin. The smartphone will reboot without superuser rights, but with the bootloader unlocked saved.
What if Magisk is not removed?
Reset via Recovery Mode and Fastboot
A more radical but effective way is to use Restore Mode, which allows you to clear the data partition where you store settings and user data, but it does not always delete the binary su file itself from the system partition if the modification was deep.
To enter Recovery mode, turn the device off completely. Then press the Up Volume and Power buttons simultaneously. Hold them until the Mi logo appears, then release the Power button while still holding the volume. From the menu that appears, select Wipe Data.
If a simple reset didn't work and the rights were preserved, you'll need to use Fastboot mode. Connect the phone turned off to your computer by holding the Volume Down button. On your PC, through the command line console, type a command to clean:
fastboot erase userdataAfter completing the command, enter the command to reboot:
fastboot reboot๐ก
Use only the original cable when connecting to your PC in Fastboot mode, as cheap cables often only provide charging and donโt transmit data, leading to a connection error.
Full return to the drain: firmware through Mi Flash
The most reliable way to ensure that any traces of interference are removed is to completely flash the device with the official global or Chinese firmware. For the Xiaomi Mi8 model (codenamed dipper), this method is the โgold standardโ.
You'll need to download the firmware image in.tgz (for Windows) from the official website. Unpack the archive into the root of the disk, such as a folder. C:\xiaomi_rom. The path should not contain Cyrillic symbols or spaces.
Launch the Mi Flash Tool on behalf of the administrator. Put your phone in Fastboot mode (down volume button + cable connection). Press the Refresh button in the program to detect the device. In the bottom menu, select the "Clean all" option to erase all data and unlock.
Press the Flash button and wait for the process to be completed. The green progress bar will come to the end and the phone will automatically reboot. This action also blocks the bootloader if you select the Clean all and lock option, returning the device to the out-of-the-box state.
| Parameter | Value for the Mi8 | Note |
|---|---|---|
| Code name | dipper | Important for finding firmware |
| Processor | Snapdragon 845 | Architecture arm64 |
| Firmware mode | Fastboot | Required for Mi Flash |
| BL lockdown | Possible. | Only with the Clean All option |

Full flashing through Mi Flash is the only way to hide the fact that there are Root rights from the most stringent security checks.
Verification of the rights of the superuser
After all the procedures, you need to make sure that the system is really cleaned, and you can use specialized utilities that scan the presence of su binary files and modified system libraries.
Install the Root Checker app from Google Play, launch it and click Check Root. If the process is successful, you will see a message that the device has no superuser rights.
You can also check the status of SafetyNet. Download the YASNAC app or analogue. Check that if both (Basic Integrity and CTS Profile Match) are marked green, then the system is considered safe for banking applications.
โ ๏ธ Note: If after all the manipulations in Fastboot mode, the status "Locked" is displayed, but the system is unstable, you may have blocked the bootloader on the custom Recovery.
Possible problems and solutions
Unforeseen difficulties may arise in the process of returning to factory state, such as a device that can go into a cyclic bootloop, in which case only re-entering Recovery mode and resetting data, or flashing through EDL mode, will help.
If your computer doesn't see your phone in Fastboot mode, check Windows Device Manager. The device may appear as "Unknown Device." In this case, you need to manually update the driver, indicating the path to the folder with Xiaomi or Google USB drivers.
Users also often encounter a Flash All Lock error when trying to block a bootloader, which occurs if the device has global firmware installed over Chinese (or vice versa), in which case it is impossible to lock without changing the firmware region to the corresponding one.
โ ๏ธ Warning: Never interrupt the firmware process by disconnecting the cable.This can damage the persist or modem partition, which will result in loss of the cellular signal and inability to make calls even after the system is restored.
