Modern Xiaomi smartphones have powerful hardware, but even a reliable Android operating system sometimes fails. The appearance of a “boot” (infinite reboot), system errors or the desire to install custom assembly require radical measures.
Software recovery process through USB-The interface allows you to bypass standard update methods that may not be available in case of critical system errors. Using a PC gives the user full control over the process of writing data to the phone’s memory, allowing you to install both official global versions and regional builds. MIUI It is important to understand that this action requires carefulness and strict adherence to the sequence of steps.
In this guide, we will discuss in detail all the stages of preparation, from downloading the necessary utilities to the final installation of the system. You will learn how to correctly transfer the smartphone to a special boot mode, what drivers are necessary for proper operation and how to avoid common errors that can turn the device into a “brick”.
Preparation for the procedure of flashing the device
Before we start directly recording system files, it is necessary to ensure a stable connection between the computer and the mobile device. USB-The cable plays a critical role: use the original wire or certified analogue with sufficient bandwidth. Cheap charging cables often do not support data transmission, which will lead to permanent connection breaks at the most inopportune time.
The next step is to back up all the important data. The process of firmware through the computer usually involves completely cleaning up the internal memory of the smartphone. Contacts, photos, documents and correspondence in messengers will be irretrievably lost if you do not take care of saving them in advance.
⚠️ Warning: Before any manipulations, make sure that the smartphone battery is charged at least 60%.Sudden power outage during the recording of system partitions can lead to irreversible damage to the bootloader.
You also need a Windows computer. While there are tools for Linux and macOS, the manufacturer's core software, such as the Mi Flash Tool, is optimized for Windows. Make sure there's enough free space on the hard drive to store firmware images and temporary files.
- 🔌 Original. USB-cable or quality analogue with data transmission support.
- 💾 External drive or cloud storage for backup user data.
- 🔋 Battery charge of the smartphone at least 60% for stable operation.
- 💻 PC with Windows 10 or later operating system.
☑️ Firmware readiness
Necessary software and search for the right firmware
The centerpiece of the process is the Mi Flash Tool, which is the official software developed by the company's engineers for service centers, which takes over the bootloader function, transferring system images to the appropriate parts of the device's memory, and downloading the current version of the program is best from proven resources or an official community forum.
The critical step is to choose the right firmware file. Xiaomi devices have different build types: Global (global), EEA (European), RU (Russian) and China (Chinese). When choosing, you need to pay attention to the type of firmware: we need a version for recovery through Fastboot, which usually has the.tgz extension, rather than.zip, designed to update "over the air".
The firmware archive must be unpacked into the root folder of the disk or into any other directory, the path to which does not contain Cyrillic characters or spaces. The firmware may incorrectly process the path if the folder name will be Russian letters. After unpacking, there should be a folder with many subfolders and files, among which the key is the launch script.
Where do I look for firmware?
Don’t forget to also install relevant USB-driver ADB And Fastboot. Without them, the computer won't see the phone in bootloader mode. Often they come with the Mi Flash installer, but they can be installed separately through Device Manager.
- 🛠 Mi Flash Tool of the latest version.
- 📦 Fastboot firmware file (.tgz extension) for your model.
- 🔗 Qualcomm drivers or MTK, also ADB/Fastboot.
- 📁 Archivator for decompressing files (for example, 7-Zip WinRAR).
Installation of drivers and setup of Windows environment
Windows may not recognize a smartphone in deep diagnostics without the right drivers. Qualcomm processor-based devices require Qualcomm HS-USB QDLoader 9008 drivers, and MediaTek requires the appropriate Preloader drivers. Installation often occurs automatically when you connect the device, but in case of failures you will have to use a Device Manager.
Open the Device Manager and plug the phone off by holding a specific button combination (usually volume down). QHSUSB_BULK, You need to manually update the driver. Choose the path to the folder with the drivers you downloaded earlier and wait for the installation to succeed.
⚠️ Note: When installing drivers in Windows 10 and 11, you may need to disable the driver digital signature check. This is done through the system boot settings, otherwise the installation may be blocked by OS protection.
Once installed successfully in the Device Manager, the Android Bootloader Interface or similar name should appear in the Ports (COM and LPT) section, which signals that communication between the PC and the phone is correct, and only after this status appears, it makes sense to launch the Mi Flash program.
In some cases, you need to activate the developer mode in the phone settings before it breaks, but this is usually not required for the Fastboot method, since the boot mode is at a lower level than the operating system.
- 🖥 Open Device Manager in Windows.
- 🔌 Connect your phone in Fastboot mode.
- ✅ Make sure the device is identified without errors.
- 🚫 Disable the antivirus during the procedure to avoid blocking.
Translation of the smartphone to Fastboot mode
Fastboot mode is a special debugging protocol built into the Android bootloader that allows you to send commands directly to the device, bypassing the operating system. This is the mode in which new partitions are written. To enter this mode on a switched-off Xiaomi device, you need to press the volume button and, holding it, connect the USB cable to the computer.
The smartphone should display a distinctive FASTBOOT logo with a hare repairing an android. If you see this screen, then the phone is ready to receive commands. In some rare cases, if the standard Fastboot does not work or is locked, you may need an EDL mode (Emergency Download Mode), but for a standard flashing, a regular fastboot is enough.
💡
If the phone goes into reboot instead of logging into Fastboot, try clamping the volume button a little earlier, before the cable is connected, or use a shorter one. USB-cable.
Check the status of the device in Mi Flash. After connecting in Fastboot mode, click the Refresh button in the gate. The list should show the connected device with its unique identifier. If the list is empty, check the drivers or try another one. USB-port, preferably located on the back of the system unit.
It is important not to confuse Fastboot mode with Recovery mode. Recovery is used to reset settings or install updates through the menu of the phone itself, whereas Fastboot is designed to interact with an external PC. You can switch from Recovery to Fastboot by selecting Reboot, but it is easier to immediately enter the desired mode with the buttons.
- 📴 Turn off your smartphone completely.
- 🔽 Press the Volume Down button (Volume Down).
- 🔌 Connect. USB-cable to PC by holding the button.
- 🐰 Make sure the Fastboot logo appears on the screen.
The process of firmware through the Mi Flash Tool
Run the Mi Flash Tool on behalf of the administrator, which will provide the necessary permissions to write to the system areas of the disk and USB ports. In the program interface, press the Select button and specify the path to the folder where you previously unpacked the archive with the firmware.
At the bottom of the window are three important firmware modes: Clean all cleans the device memory and installs a clean system, which is a recommended option for treating errors. Save user data tries to save user files, but it can lead to unstable work if the software versions are very different. Clean all and lock mode also clears the data, but re-blocks the bootloader, which is necessary for the operation of some banking applications and Mi Pay.
⚠️ Warning: Selecting the "clean all and lock" option on a device with Chinese firmware or a modified bootloader can result in a device lock (Hard Brick.
Once you have chosen the path and mode, press Flash, start a firmware process that displays progress in percentages and color indications, and it is strictly forbidden to turn off the cable or interrupt the program before the Flash Done message appears.
💡
Use the "clean all" mode for stable system operation after changing the firmware region or treating errors to avoid conflicts between old files and the new OS version.
Waiting time depends on the volume of firmware and speed USB-The process usually takes from 200 before 600 After completion, the phone will automatically restart. The first load may take longer than usual (until the end of the day). 10-15 minutes), as the system optimizes applications and creates new configuration files.
- 🚀 Launch the Mi Flash Tool on behalf of the administrator.
- 📂 Click Select and specify the folder with unpacked firmware.
- 🧹 Select "clean all" mode for clean installation.
- ▶️ Press Flash and wait for the process to be completed.
Common mistakes and ways to solve them
Users often encounter different error codes during the firmware process, one of the most common being Error: Flash All Except Data Storage or partition incompatibility errors, which often occur when trying to flash firmware for another region (e.g. Global on China) without unlocking the bootloader or when choosing the wrong cleaning mode.
The Miss matching image and phone error indicates that the firmware chosen is not intended for the device model. Check the codename in the settings or on the box and compare it to the firmware file name. A mismatch in even one letter can result in a firmware failure or failure.
If the process is stuck on a certain percentage (for example, 14% or 56%), this may indicate problems with drivers, cable or USB port. Try reconnecting the cable to another port (preferably USB 2.0), reinstall ADB drivers or use another computer. Sometimes antivirus software can block file recording, so temporarily disabling it often solves the problem.
| Error code | Probable cause | Decision-making |
|---|---|---|
| Miss matching image | Wrong firmware model | Download firmware for the exact code name of the device |
| Flash All Except Error | Data section conflict | Use Clear All mode instead of Save User Data |
| Device not found | Problems with drivers or cable | Reinstall drivers, change drivers USB-port |
| Anti-rollback check failed | Attempting to roll back the Android version | Only request an updated or newer version of the software |
There's also an Anti-rollback protection that prohibits you from installing an older version of Android than the one you had before, which is a security measure that you can't get around with standard means, and if you try to do that, it will give you an error and the phone will go into protection.
Completion of installation and initial setup
Once the process is successfully completed and rebooted automatically, the device will begin a long initial launch procedure.The screen can remain black or show the brand logo for 5-10 minutes.This is normal behavior for Android after completely clearing the memory, file system creation and indexing are underway.
When the phone finally boots up, you'll be greeted by a language selection welcome window, which is important to connect to the Wi-Fi network to activate the device, and if you've used bootloader lock mode, the phone will require authorization through the Mi Account that was previously linked, or prompt you to enter a new one.
It is recommended to check the version of the software in the Settings → About Phone section immediately after download and make sure it matches the one you installed. It is also worth checking the main modules: camera, sound, touch screen and communication modules to ensure that the device is fully functional after flashing.
Now your Xiaomi smartphone is ready to work with a clean and fast system, and regular software updates and caution when installing applications from unknown sources will help avoid the need to re-flash in the future.
