The process of replacing software on Xiaomi devices is often a necessity for those who want to get new features or fix system errors. Users are faced with a situation when automatic update does not come, or the device has a Chinese version of the MIUI shell that does not support Russian language and Google services.
There are several basic methods of installing a new operating system, each with its own features and preparation requirements. The most common ways are to upgrade through Recovery mode and use the specialized Mi Flash Tool in Fastboot mode. The choice of the specific method depends on the current bootloader lock, the region of use of the device and the desired result.
It is important to understand that interference with system files always carries certain risks that must be considered before starting a procedure. Mistakes can lead to the loss of warranty or turn a smartphone into a βbrickβ requiring hardware repair.
Preparation of the device and choice of firmware
The first and most important step is to find and download the right installation file for your particular model. You need to know exactly the device encoding, which can be found in the Settings β About Phone section, so as not to confuse the global version with the Chinese or Indian one.
Firmware files usually have a.zip extension for the Recovery method and an archive format for Fastboot mode. software should be downloaded exclusively from trusted sources, such as the official developer site or authoritative forums where files are checked for integrity and the absence of malicious code.

Always check the checksum of the downloaded file, if this is provided by the download source, to ensure the integrity of the data.
In addition to the file itself, you'll need to ensure that the smartphone is connected to the computer in a stable manner. USB-cable, as cheap analogues are often not able to provide the necessary data transfer speed and tab, which is critical when writing system partitions.
Recovery Mode Update Method
This method is considered the most secure for beginners, since it does not require unlocking the bootloader and complex software on the PC. The process consists in manually running the installer through a hidden recovery menu, where the pre-downloaded archive with the update is placed. This method is ideal for switching between versions of a single branch, for example, with China. ROM Globally ROM, If permitted by company policy.
To start, place the firmware file in the root of the deviceβs internal memory without packing it into additional archives. After that, go to the Settings β About phone menu and quickly click on the MIUI kernel version several times to activate the hidden menu. In the window that appears, select Select the firmware file and specify the path to the downloaded archive.
The system will automatically check the compatibility and integrity of the data, then request confirmation to restart. If the file is damaged or not suitable for this model, you will see an error message and the process will not begin. If successful, the device will restart and begin the installation process, which can take from 5 to 15 minutes.
βοΈ Pre-installing check
There is an important limitation: this method will not allow you to downgrade the Android version or upgrade from a newer version of MIUI to an older one without completely clearing the data, and you can not switch from global firmware to Chinese or vice versa unless you completely reset your settings, as partition structures may differ.
Installation with Fastboot and Mi Flash Tool
Fastboot is a more powerful tool that allows you to completely reinstall the operating system from scratch. It requires a Windows computer, installed ADB drivers and a specialized utility Mi Flash Tool. This method is often used to restore devices after critical failures or to change the firmware region.
Before the procedure, you need to unlock the bootloader through the official Mi Unlock service, which requires an account to the device and a wait of 7 to 168 hours. After obtaining permission, the bootloader is put into command standby mode, and the phone connects to the PC with a clamped down button, which is displayed on the screen with the image of a rabbit repairing an android.

If the drivers are installed correctly, the serial number of the phone will appear in the list. Next, click Select and specify the path to the unpacked firmware folder, then select Clean All mode for clean installation or Save User Data for saving files.
Press the Flash button to start the process. The progress bar will show the status of the operations, which can take from 200 to 600 seconds. Upon completion, the phone will automatically restart, and you will see the MIUI logo, indicating the successful completion of the procedure.
