Owners of Xiaomi, Redmi and Poco smartphones often face the need to completely reinstall the operating system, which can be caused by critical errors in Android, the inability to boot after a failed update, or the desire to change the firmware region. Unlike the standard update “over the air”, the method using the MiFlash utility allows you to perform deep cleaning of memory parts and restore the device even from the “brick” state.
The process requires carefulness and precise follow-up to the algorithm, as interference with low-level partitions of memory carries certain risks. the Fastboot interface used for the firmware takes precedence over the system boot loader, which allows you to overwrite system files directly. Before proceeding to, you need to make sure that the original cable is serviceable. USB-port on the computer and sufficient battery charge of the device.
The main advantage of this method is the ability to completely reset the structure of the file system, which often solves problems that are invisible to ordinary users. However, using Fastboot ROM requires prior unlocking the bootloader, unless you change the region to the same.
Toolkit preparation and firmware selection
The first step is to find and download the correct image of the system. You need a Fastboot ROM that has the extension.tgz, not Recovery ROM with the extension.zip. You can find current versions on official resources or verified archives, such as Xiaomi Firmware Updater. It is important to choose the version that corresponds to the model of your device, as the firmware from Redmi Note 10 will not be suitable for the Redmi Note 10 Pro.
Once the archive is loaded, it needs to be unpacked. The folder structure should be simple: it is advisable to place the unpacked folder in the root of the disk, for example, C:\mirom\, so that the path to the files does not contain Cyrillic characters or spaces, which is critical for the work of console utilities that the MiFlash Tool uses.
You also need to download and install the software itself. The official MiFlash version often contains built-in drivers, but in some cases they have to be installed separately through the Device Manager. Without properly installed ADB and Fastboot drivers, the computer will not see the smartphone in the desired mode.
💡
Always check the checksum (MD5) of the downloaded firmware archive to ensure that the data is intact and that no download errors are present.
Installation of drivers and setting up the environment
Communication between the computer and the smartphone in deep diagnostic mode is provided by special drivers. When you connect an unlocked device in Fastboot mode in Windows Device Manager, it should be defined as Android Bootloader Interface. If you instead see an unknown device with a yellow exclamation mark, the drivers are installed incorrectly.
Devices with a locked bootloader or in EDL mode, which is needed to restore the “bricks”, require Qualcomm HS-USB QDLoader 9008 drivers. Their installation often requires disabling the driver signature verification in Windows, since they do not have a digital signature from Microsoft.
Make sure that your computer has all the necessary components in the.NET Framework and Visual C++ Redistributable, without which the program interface may not start or work with errors. Often, the problems with the “flash error” or “miss matching image” error are due to conflicting versions of libraries or lack of administrator rights.
What if the driver is not automatically installed?
Modes of operation: Fastboot and EDL
There are two main modes for firmware through MiFlash: Fastboot, which is available on most unlocked devices, you need to turn off your phone and press the volume button, then connect the cable to your PC, and you'll see a picture of a hare repairing an android, or the words FASTBOOT.
The second mode is EDL (Emergency Download Mode), designed for service centers and deep recovery, in which the device screen remains black, and in Device Manager the port is defined as Qualcomm HS-USB QDLoader 9008. Entering this mode on modern models often requires disassembling the phone and closing special contacts on the board, or having an authorized Mi Account.
The mode choice depends on the state of your smartphone. If the system reacts or the bootloader is unlocked, use Fastboot. If the phone is not showing signs of life, does not respond to buttons and only vibrates when connected to charging, you will probably need EDL mode and professional equipment.
Step-by-step instructions for firmware
Launch MiFlash on behalf of the administrator. In the top menu, click the flash button (or flash_all), You can select a firmware script. Then press select and point the path to the folder with the unpacked firmware. The program will automatically check for the image file and the script. flash_all.bat.
Connect your smartphone in Fastboot mode to your computer. Press the refresh button in the program. If the drivers are installed correctly, a device with its unique identifier will appear in the list. If the field is left empty, check the cable or reinstall the drivers.
☑️ Checklist before launch
Once the device is found, select the firmware method at the bottom of the window. To clean the data completely and install a clean system, choose clean all. If you want to save data (not recommended when changing region), choose save user data. To completely re-mark up the partitions (dangerously, IMEI can fly on some models), clean all and lock is used.
Press the flash button to start the process. The progress bar will show the status of the execution. At this time, you can absolutely not turn off the cable or interrupt the power. The process takes from 200 to 600 seconds, after which the phone automatically restarts.
| Parameter | Description | Recommendation |
|---|---|---|
| flash_all | Complete data cleanup | Recommended for clean installation |
| flash_data_only | Update without data loss | Only to update the MIUI version |
| flash_all_except_storage | Cleaning the system, saving photos | Balance between cleanliness and data |
| flash_all_lock | Locking the loader | Only for the original regional firmware |
Common Errors and How to Resolve Them
One of the most common problems is the Miss matching image and current device error. It occurs when you try to install firmware that is not intended for the code name of your device (for example, the firmware for lmi to the gauguin device).
The Not enough storage space error can occur if you try to downgrade the Android version without first unlocking the bootloader or using special scripts. Anti-Rollback protects against installing the old version of the software to close security vulnerabilities.
If the process is stuck on a certain percentage (for example, 6% or 98%) and gives a timeout error, try changing the timeout. USB-Port (it is desirable to use the port) USB 2.0 on the back of the motherboard, or replace the cable, and restarting the service helps. ADB task-manager.
⚠️ Note: Use a clean all and lock command on firmware that does not have a region similar to the device (e.g. Global) ROM In Chinese, it will result in an infinite bootloop, and you can only restore the device through the mode. EDL.

⚠️ Warning: After the first download of the flashed device, the system can cache applications and optimize the work for up to 10 minutes. MI.
Successful firmware installation via MiFlash returns factory performance and eliminates software conflicts. The main thing is to carefully monitor the choice of firmware method and the compliance of the device model. Regularly backing up important data before any manipulation of the system will save your photos and contacts in case of unforeseen circumstances.
💡
The key to successful firmware is the use of the original cable, a direct USB port on the motherboard and the exact matching of the code name of the firmware model of the device.
