Restoring a smartphone or switching to a global version of the operating system often requires the use of specialized software. The MiFlash Tool is the official solution from the manufacturer to work with the bootloader in Fastboot mode. It is a powerful method that allows you not only to update the software, but also completely clean the device from errors that arose as a result of failed experiments or system failures.
The process of flashing through a computer is radically different from the standard “over the air” update, where you get full control over the memory partitions, which allows you to change the region, lower the Android version or restore the “brick” after a failed unlock, but this power requires increased attention to detail and strict adherence to the sequence of actions.
In this article, we will discuss in detail the preparation of the environment, the choice of the right image file and the algorithm of actions. You will learn how to avoid typical driver errors and what to do if the utility stops seeing the connected gadget. Competent training is ninety percent of the success of the entire operation, so do not neglect the theoretical part.
Preparation of the working environment and necessary files
The first step is to download the current version of the MiFlash utility.It is recommended to use the latest stable releases, as older versions may not work correctly with new models of smartphones released after 2023.
In parallel, you need to find and download the firmware itself. Fastboot requires a file with the.tgz extension, not.zip, which is used to update through Recovery. The archive must match your device model and desired region. It is important to check that the firmware version of Android is not lower than the one installed now, unless you plan to do a full downgrade with the unlocked bootloader.
Be sure to install current drivers ADB Without them, the computer will not be able to correctly identify the smartphone in boot mode. USB-gadget, which makes further work impossible.
☑️ Firmware readiness
Make sure the USB cable you plan to use is serviceable and supports data transfer, not just charging.Cheap unshielded cables can cause connection breaks at a critical point in the memory sectors' writing, with fatal consequences.
Modes of operation: Fastboot vs. Recovery
Understanding the difference between boot modes is critical to choosing the installation method. Fastboot is a low-level protocol that allows you to send commands directly to the bootloader of a device without bypassing the operating system, and it is this mode that MiFlash uses to deep-flash all partitions.
Recovery is a recovery-level mode that is often used for simple upgrades or resets, but MiFlash is focused on Fastboot, as it is the only one that allows you to execute a command. clean_all, completely erasing user data and partition structure.
⚠️ Note: When running through Fastboot, antivirus programs may block drivers, and it is recommended to temporarily disable real-time protection during the procedure.
To get to the desired mode on the device turned off, you need to press the key combination. Usually this is the Volo and Power button, and the image of a rabbit repairing an android will appear on the screen, which signals readiness to receive commands.

Step-by-step instructions for installing firmware
After unpacking the firmware archive, the path to the folder should not contain Cyrillic characters or spaces. C:\Xiaomi\ROM\. Run XiaoMiFlash.exe on behalf of the administrator to avoid problems with access rights to system ports.
In the program interface, press the Refresh button. If the drivers are installed correctly and the phone is connected in Fastboot mode, a device with a unique identifier will appear in the list. If the list is empty, check the Windows Device Manager for unknown gadgets.
At the bottom of the window, select the firmware method. To clean the data completely and change the region, select the Clean all option. If you want to save data (not recommended when changing Android versions), you can choose Clean all and lock, but only if the firmware matches the current region of the bootloader.
💡
Use it. USB-port located on the motherboard behind the system unit, rather than on the front panel or through USB-This will provide stable voltage and minimize the risk of data packet loss.
Press the Flash button to start the process. The progress bar will show the steps of writing partitions. At this time, it is strictly forbidden to turn off the cable or interrupt the computer. The process can take from 300 to 600 seconds depending on the memory capacity and port speed.
| Parameter | Description | Recommendation |
|---|---|---|
| Flash All | Complete Firmware with Data Saving | Not recommended for changing versions |
| Clean All | Complete data deletion and firmware | The Best Choice for Stability |
| Clean All + Lock | Firmware and loader lock | Only for the original region |
Solving Common MiFlash Errors
One of the most common problems is the MissMatching image and device error, which occurs when you try to install firmware that is not designed for a particular model, for example, you can not flash the global version to a device with a Chinese bootloader without first unlocking and changing the region.
Flash fail or Flash error often indicates problems with cable, port or drivers. USB-cable, reconnect your device to another port, or reinstall Qualcomm or MediaTek drivers, depending on your smartphone’s processor.
- 🔴 Device busy error – phone busy, try rebooting in Fastboot.
- 🔴 Not enough space error – the firmware file is damaged or the wrong cleaning method is selected.
- 🔴 Driver Error – Check driver signatures in Windows Device Manager.
If the process is stuck at a certain percentage (e.g., 34 percent or 56 percent) and does not move for more than 10 minutes, the partition record will likely fail, in which case you need to interrupt the process, remove the battery (if possible), or press the power button for 15 seconds to restart, and then try again.
Features of the loader lock
Locked Bootloader imposes severe restrictions on the firmware process, you can't install custom Recovery or unofficial firmware, and trying to flash the global version onto a Chinese machine with a closed bootloader will result in a signature verification error.
Changing the region from CN to Global requires unlocking through an official MIUI application. Once unlocked, the status will change to Unlocked, allowing you to use Clean all mode to change region. However, after firmware is done, the bootloader will automatically lock again if you select the appropriate option.
⚠️ Warning: Locking the bootloader after installing global firmware on a Chinese device can cause a cyclic bootloop if the software versions are incompatible. Always check compatibility before blocking.
The bootloader status check is done by a combination of buttons at launch or via a command in the console. If you see a Locked sign, MiFlash's capabilities are limited only to official scenarios for your region.
Post-firmware: setup and recovery
Once you've successfully completed the process and booted the system for the first time, you'll be greeted by the initial setup screen, because the Clean all method deletes data completely, the phone will be like new. Don't rush to restore the backup right away.
It is recommended to first update the applications through Google Play and check the basic communication modules, make sure that Wi-Fi, Bluetooth and mobile network are working, and then you can start installing applications from the backup.
💡
The first download after the firmware can last up to 10-15 minutes, which is normal because the system optimizes applications and creates cache.
If you have problems with your sensor or camera, try resetting to factory settings from the system’s menu, and sometimes the remnants of old configuration files may conflict with the new firmware version.
