Changing the regional version of the operating system or restoring a smartphone after a failed update are challenges that many owners of Xiaomi devices face. Flashing through a computer is the most reliable method to not only bring the gadget back to life, but also install a global version of the software instead of the Chinese one.
Using a PC to install firmware opens up access to Fastboot mode, which runs at a deeper level than standard recovery. OTA-The Wi-Fi updates, the computer method, allow you to force the old data to be erased and the new system installed, which often solves problems with bugs and unstable interfaces. It is important to understand that you take responsibility for actions with the device's software code.
Before you start active actions, you need to make sure that there is a stable Internet connection and a serviceable one. USB-A mismatched cable model or poor port contact can interrupt data transmission at a critical moment, leading to errors. Next, we will discuss all the stages of preparation and the installation process itself.
Preparation of equipment and choice of firmware
The first step is to find the correct firmware file that matches exactly your smartphone model. Aggregator sites offer many versions, but manually installed via PCs are best suited to.zip archives labeled "Fastboot." Don't confuse them with Recovery versions, which are designed to be installed through the phone's recovery menu.
You will need a computer running Windows, as the Mi Flash Tool does not have official versions for macOS or Linux without emulators. It is also critical to use an original or quality certified cable that can transmit data, not only charge the device. Cheap “charging only” cables will not allow the computer to see the smartphone in bootloader mode.
Make sure to back up all your important data, as the Clean All flashing process will completely destroy the information on the internal drive, save contacts, photos and documents to the cloud or to an external hard drive in advance. Once you start the procedure, you will not be able to return deleted files without a backup.
Check the space available on your computer's hard drive. Firmware archives can take anywhere from 3 to 5 GB, and they require additional space to unpack, and a lack of space can lead to errors in file extraction or malfunctioning of the firmware utility.
Required drivers and utilities
For successful communication between the computer and the smartphone, you need to install specialized drivers ADB and Fastboot. Without them, Windows will not be able to recognize the connected device in a special mode and will see it as an unknown gadget. These drivers are usually part of the SDK Platform Tools platform from Google.
The second must-have component is the Xiaomi Mi Flash Tool itself, an official software developed by the company’s engineers to service their devices. There are many modified versions of this ulite, but to ensure stability, it is recommended to use the latest official build available on the community forum or official website.
☑️ Firmware readiness check
Often, there is a driver conflict if other Android devices have previously connected to your computer, in which case it is recommended to clear the list of previously connected devices in Windows Device Manager, which will help avoid situations where the computer tries to use the wrong driver for your Xiaomi.

Unlocking the bootloader (Bootloader)
The official flashing of the global version to a Chinese smartphone or switching from one regional firmware to another often requires an unlocked bootloader. Bootloader is a program that runs before the operating system is turned on and checks the integrity of the software.
To unlock, you need to apply via the Mi Unlock app on your PC, pre-assigning your Mi Account account to your phone settings. The process is not instantaneous: after submitting an application, the system may require a wait of 7 to 168 hours (from a week to a month), a measure of protection against device theft and unauthorized firmware reflash.
It is important to understand that unlocking the bootloader automatically results in a complete data reset (Wipe Data). Even if you just unlock it and do not change anything, the phone will return to factory settings. In addition, on some models, the banking application or Google Pay may stop working after this procedure without additional manipulation of root rights.
⚠️ Warning: After unlocking the bootloader, some security features like Widevine L1, may be reduced to a level L1 or L3, Which will limit the viewing experience HD-The guarantee from the manufacturer in some regions may be canceled.
If you plan to simply restore your phone after a crash, check if your current version of the software allows you to roll back or install the same version without unlocking. In some cases, if regions coincide, installation via Fastboot is possible with a locked bootloader, but these are rare exceptions.
Instructions: Firmware via Mi Flash Tool
After you have all the files ready and unlocked the bootloader, you can proceed to the main process. First, unpack the downloaded archive with the firmware in the root of the C disk or any folder with a short path, for example, C:\ROM\. The path should not contain Cyrillic symbols or spaces, otherwise the utility will not be able to find files.
Put your smartphone in Fastboot mode. To do this, turn off the device completely, and then press the volume button and, without letting it go, connect it. USB-The Fastboot logo should show on your smartphone screen, with a picture of a hare repairing an android. If that doesn't happen, try another one. USB-port.
💡
Use it. USB-ports soldered directly on the computer motherboard (behind the system unit), rather than the front ports of the housing or USB-This will provide stable voltage and data transmission.
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button and your device with its unique code should appear in the list. If instead of the code, an error or field is displayed empty, check the installed drivers in the Device Manager.
At the bottom of the utility window, select firmware mode. There are three options available:
- 🟢 Save user data – saves all data (only works if the firmware version is higher or equal to the current one).
- 🔴 Clean all – clean all data (recommended when changing the region or version of Android).
- 🔴 Clean all + lock – clears the data and re-blocks the bootloader (use only when installing the original regional firmware!).
Press Flash and wait until the process is over. The status bar will be filled in green. Under no circumstances turn off the cable or restart the phone manually until the "Success" message appears in green. The entire process takes 300 to 600 seconds.
Solving mistakes and problems
During the firmware process, users often encounter error codes, one of the most common is Miss matching image and device, which means that you are trying to flash firmware that is not intended for the given code name of the device (for example, the firmware from Redmi Note 9 Pro on Redmi Note 9).
The Anti-rollback check failed error indicates an attempt to roll back the Android version to an older version, which is prohibited by security policy. Anti-rollback protection does not allow you to install a version of the software with a lower index than the one already on the device, in which case only installing the current or newer version will help.
| Error code | Description of the problem | Method of decision |
|---|---|---|
| Flash error | Disconnection or driver failure interrupted | Replace USB-cable, port, reinstall drivers |
| Unlocked bootloader needed | bootloader locked | Unlocking with Mi Unlock Tool |
| Not enough space | Not enough space in the phone memory | Select Clean All mode, make room |
| Flash storage error | Problem with device memory | Repeat the attempt, check the integrity of the firmware file |
If the process is stuck at a certain percentage (e.g., 54% or 98%) and does not move for more than 10 minutes, most likely there was a failure.Forcing the restart (pressing the power button for 10 seconds) and try to start the procedure again, pre-selecting another one. USB-port.
First start and set up system
Once the firmware is successfully completed, the phone will automatically restart. The first run can last longer than usual, up to 10-15 minutes, as the system optimizes applications and creates new configuration files. Don't panic if the screen is lit with the Mi or Android logo for a long time.
At the initial setup stage, the system may request a Wi-Fi connection and a Mi Account login.This is a standard activation check procedure, especially if the bootloader has been unlocked or reset. Make sure the date and time on the device are set correctly, as this affects the operation of security certificates.
💡
The first run after a complete cleanup (Clean All) always takes longer than a normal restart.
It is recommended to check the system version in the About Phone section immediately and update security components if micro-updates are available, and check the main modules: the camera, microphone and sensor to make sure that the drivers of the new firmware work correctly.
⚠️ Warning: If your phone goes into an endless bootloop after you have firmware, try resetting it via Recovery mode (Wipe Data). If that doesn't help, you may have selected an incompatible version of the software or damaged the firmware file when you download it.
