Modern smartphones Xiaomi, Redmi and POCO work on the basis of the Android operating system with a proprietary shell MIUI Sooner or later, every user is faced with the need to reinstall the software, which may be caused by the desire to upgrade to the latest version, if the user is not able to do so. OTA-The notification never came, or the need to restore the device after a failed experiment, virus attack or system failure.
The process of replacing system software requires care and preparation, but it is quite accessible even for beginners. The firmware is not just an update file, but a complete image of the operating system that is written to the device's memory. Unlike a conventional "over-the-air" update, manual installation gives full control over the software version and allows you to solve complex software problems that cannot be fixed by standard reset methods.
In this article, we will look at where to look for official files, how installation methods differ, and what precautions you need to follow, learn how to distinguish between types of archives, understand the logic of Recovery and Fastboot modes, and learn how to avoid turning a smartphone into a “brick.”
Where to look and how to choose official firmware files
The first and most critical step is to find the right file.The Internet is full of modified builds, but for the stable operation of the device, it is strongly recommended to use only the original software from the manufacturer.The official files are distributed free of charge and do not contain malicious code or hidden miners.
The main source of distributions is miui.com or specialized proven aggregator resources such as xiaomirom.com. When searching, you need to know the exact codename of your device (codename), which often differs from the marketing name. For example, the Xiaomi Redmi Note 10 Pro smartphone has the codename sweet, and the Xiaomi Mi 11 is venus.
- 🔍 Determine the exact model of the device in the section "About the phone».
- 🌍 Select the desired region: Global (Global), EEA (Europe, Russia (Russia) or China (China).
- 📂 Download the archive corresponding to the desired installation method (Recovery or Fastboot).
- 🔒 Check the integrity of the file through the checksum, if this is possible.
⚠️ Warning: Never try to install firmware from another phone model, even if they look the same. Code names must match completely, otherwise there is a high risk of irreversible damage to the bootloader.
The firmware files are large, usually 3 to 6 gigabytes in size. Make sure you download them from a stable Internet connection to avoid damaging the archive when downloaded. After downloading, it is recommended to check the file extension: for the Recovery method it is usually.zip, and for Fastboot it is.tgz.
Differences between Recovery and Fastboot versions
Beginners are often baffled by the two main types of archives to install. Understanding the difference between them is key to choosing the right method. Recovery ROM is designed to be installed through the built-in recovery menu of the smartphone itself, without using a computer. It's a simpler, but less flexible way.
Fastboot ROM requires a PC connection and special software. This method provides deep access to the system, allowing not only to update, but also to completely clean partitions of memory, change the region of the device or even downgrade the Android version (with the bootloader unlocked). Fastboot firmware weighs more and contains full images of all partitions of the system.
If you plan to upgrade or switch between regions of the same version (for example, from Russia to Global), a Recovery file will suffice. However, if the phone hangs on the logo or you want to install the system completely from scratch, the Fastboot method will be more reliable.
Preparing a smartphone and computer for flashing
Before you start active, you need to properly prepare the workplace. Chaotic actions in the process of writing system files can lead to data loss or errors. Charge your smartphone to at least 60-70%, as the process can take from 15 minutes to an hour, and a power surge or battery discharge is unacceptable.
Make a full backup of important data: contacts, photos, instant messengers. During the firmware process, especially when choosing the Clean install option, all information on the internal drive will be irretrievably deleted. Use Google Drive or Xiaomi Cloud cloud services, or copy files to your computer.
☑️ Checklist before start
To work with Fastboot mode, your computer must have ADB and Fastboot drivers installed, as well as the Mi Flash Tool (for Windows). Without these components, the computer simply won't see the phone in bootloader mode. Also make sure that there are no Cyrillic characters or spaces on the disk where the firmware is unpacked on the way to the folder.
Instructions: Install firmware through Recovery
This is a good method if the phone is switched on and running smoothly. First, place the downloaded.zip file in the root of the device's internal memory. Don't put it in folders, just in the main space. Then go to the update menu through the settings or a special recovery menu.
To enter the Recovery menu manually, turn off your phone and press the Volume Up + Power button combination. From the menu that appears, select the language (usually available in English and Chinese, but there are also Russian in some versions). Next, select Wipe Data if you want to reset, or immediately go to the installation.
| Action. | Description | Risk of data loss |
|---|---|---|
| Update via ZIP | Selecting a firmware file from memory | Low (retains data) |
| Wipe Data | Full reset to factory settings | Tall (removes everything) |
| Wipe Cache | Clearing temporary files | No (only cache) |
| Reboot | Reboot to the system | No. |
Select Install update or Choose update package and specify the previously downloaded archive. The system will check the integrity of the file and begin the installation process. During this time, the phone may reboot several times. Do not interrupt the process or press buttons until the desktop or welcome window appears.

Fastboot Method: Professional Installation via PC
To use this method, you will need the Xiaomi Flash Tool. Unpack the downloaded firmware archive (.tgz format) into the root of the disk, for example, in a folder. C:\rom\. The path should be short and without Russian letters.
Put your smartphone in Fastboot mode. To do this, you need to connect the device to the PC by holding the Volume Down button. The screen will show an image of a rabbit repairing an android and the inscription FASTBOOT. In the program, press the Refresh button so that the PC sees the device.
fastboot devicesThis command in the command line (if you use the manual method through ADB) should output the serial number of the device. In the Mi Flash Tool graphical interface, you will see the path to the device. Select the firmware mode: Clean all (full reset) or Save user data (save data, does not always work when changing regions). Press Flash and wait for completion, as indicated by the green "Success".
⚠️ Note: When using the Fastboot method with the "Clean all" option, the phone may be locked if Mi Account protection is activated. Make sure you remember the username and password from the account associated with the device.
Common Errors and How to Resolve Them
Errors can occur during the flashing process. Error: can't open device most often indicates a driver or driver problem. USB-Try another port (better). USB 2.0), another cable, or reinstall drivers through Windows Device Manager.
If you see an anti-rollback bug, it means you're trying to install an older version of the software than you're currently using, and the manufacturer has blocked that, and the anti-rollback is a security mechanism that prohibits downgrade to prevent system vulnerabilities, and it's almost impossible to get around it without deep knowledge and special tools.
- 🔌 Connection error: Replace USB-cable.
- 🚫 Anti-rollback error: You can’t roll back to an older version.
- 📉 Memory error: Free up space on your PC drive or check the firmware file.
- 🔒 Blocking Mi Account: Password entry required after firmware.
💡
Use it. USB-hub without external power or connect your phone directly to the motherboard (back ports of the PC) to avoid problems with unstable voltage during firmware.
A frequent problem is the endless restloop after installation. In most cases, a full reset via Recovery (Wipe All Data) helps. If the phone does not respond to any buttons and the black screen, the device may have gone into deep EDL (Emergency Download Mode) mode, which often requires an authorized service center account to exit.
