Buying a Xiaomi smartphone from China is often a great alternative to buying an official device at local retail, which is usually much cheaper and their hardware is not inferior to the global versions, but the owner immediately faces a language barrier, the lack of Google services and the presence of excess Chinese software that consumes the system resources.
The process of software change, or flashing, allows you to turn a Chinese into a full-fledged international device, which opens up access to Google Play, Russifies the interface and eliminates notification problems, and it is important to understand that this operation requires carefulness and accurate follow-up to the algorithm of actions, since interference in the system partition carries certain risks.
In this guide, we will take a detailed look at all the preparation steps, tools and step-by-step steps needed to successfully install the Global MIUI or HyperOS. We will look at both automatic methods and manual installation through special utilities so that you can choose the most suitable option for your case.
Preparation of the device and choice of firmware
The first and most critical step is to choose the right image of the operating system. For Chinese versions of smartphones labeled as CN (China), there are two main ways: installing a global version (Global) or using a special international Chinese firmware (China ROM with Russian).
You need to make sure that the selected firmware file matches the code name of your model. For example, for Xiaomi Redmi Note 12 Pro, the code name may differ from the global version, and installing incompatible software will lead to the inoperability of the device.
What is the difference between Recovery and Fastboot firmware?
Before you start manipulating, make sure to back up all your important data. When you switch from CN to Global, your internal memory will be completely cleaned, and photos, contacts, and documents should be stored in the cloud or on your computer in advance.
💡
Use the original. USB-Cheap charging cables often don’t support high-speed data transmission, which can lead to firmware errors or process freezes at a certain percentage.
Required tools and drivers
To install the software properly, you will need not only the firmware file itself, but also a set of specialized drivers. Without the ADB and Fastboot drivers installed correctly, the computer will simply not see the smartphone in the desired mode. Most often, problems arise during the connection stage, when the Device Manager displays “Unknown Device”.
It is recommended to download and install the SDK Platform-tools platform from Google in advance. This package contains the necessary executable files adb.exe and fastboot.exe. Also, to work with the Mi Flash Tool utility, you may need Qualcomm or MediaTek drivers, depending on the processor of your device.
- 📥 Mi Flash Tool - the official utility for Windows, allowing you to flash devices through the Fastboot mode.
- 🔌 USB Drivers – a package of drivers Xiaomi, providing communication PC and smartphone.
- 💾 Firmware file – archive with extension.tgz for Fastboot method.
- 🔋 Battery charge – the charge level must be at least 60% for the safe procedure.
Installing drivers often happens automatically when you plug in your phone, but in the case of the Chinese versions, manual installation is sometimes required through Device Manager.If you use a laptop, make sure it's connected to a power source to avoid suddenly shutting down during the critical data recording phase.
☑️ Firmware readiness check
Unlocking the bootloader (Bootloader)
The key obstacle to changing the region is the blocked bootloader. Chinese smartphones come with a closed Bootloader, which prohibits the installation of third-party software. The official method of unlocking requires binding the Mi Account and waiting for a certain period of time, which can be from 7 to 168 hours (7 days).
To start, you need to activate the developer mode in the phone settings, you need to quickly click on the build number in the About Phone section several times, then in the About section of the About Phone section, you should additionally find the Mi Unlock Status item and activate unlock by linking the device to your Mi Account.
⚠️ Warning: After applying to unlock and link your account, trying to unlock the bootloader from another account again or resetting your phone settings will reset the waiting timer.Don't try to fool the system, just wait for the allotted time.
After the waiting time has expired, you need to start the Mi Unlock Tool utility on your computer, log in to the same account as on your phone, and transfer the smartphone to Fastboot mode (clamping the power and volume buttons down).
💡
Unlocking the bootloader is an irreversible guarantee action in many service centers, and it also reduces data security, as an attacker with physical access may try to reset the device.
Firmware method via Fastboot (Recommended)
The most reliable way to turn a Chinese device into a global one is to use Fastboot mode, which allows you to completely rewrite the system partition by changing the regional settings and the language package, and you will need to download the firmware archive (.tgz) to the root folder of the disk or to the path without Cyrillic characters.
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button to detect the connected device. In the address bar, specify the path to the folder with the unpacked firmware. It is critical to choose the correct firmware mode in the bottom corner of the window: Clean all (full cleaning) or Clean all and lock (clean and lock).
The Clean all and lock option is only available when you are running a global firmware version or when you are completely changing the region with the bootloader closed. If you are flashing the globalist on a Chinese machine and want to close the bootloader, make sure that the firmware is truly Global, otherwise the phone will go into a brick.
| Firmware mode | Description of action | Risks. |
|---|---|---|
| Update | Stores user data and files | Possible conflicts of system files |
| Clean all | Completely erases data, the bootloader remains open | Loss of data (a copy is needed) |
| Clean all and lock | Deletes data and closes the bootloader | High risk of region change (CN -> Global) |
Once you select the mode, press the Flash button. The process will take 200 to 600 seconds. At this time, turn off the cable or interrupt the power. Upon completion, the status message will appear "success", and the phone will automatically restart.
Installation through Recovery Mode
The Recovery update method is suitable if the bootloader is already unlocked but there is no access to the computer, or if you are upgrading within the same region (for example, from Chinese stable to Chinese developer).
Copy the firmware file into your phone's internal memory. Go to the Advanced Menu (three dots in the upper right corner of the Update app) and select Select the firmware file. Once you confirm the selection, the device will reboot to Recovery mode and start installing.
This is less reliable when changing region, because it may not affect some system parts responsible for regional settings, often after this procedure, Chinese applications remain in the phone and the geolocation definition is incorrect.
⚠️ Note: When running through Recovery, you can’t close the bootloader if your goal is to convert the machine completely for resale or return to a closed factory state. BL, This method won't work.
Possible errors and their solution
Users often encounter various bugs during the firmware process, one of the most common being Error: Miss matching image and device, which occurs when you try to install firmware that is not designed for a particular model, or when the firmware type (Global/China) does not match the current bootloader status.
Another common problem is hanging on the Mi logo (Bootloop), which can mean that the firmware has broken down or the system partition has been damaged. In such cases, Fastboot re-routing with Clean all mode helps. If the phone is not detected by the computer, try changing the system. USB-port, cable or manually install drivers through Device Manager.
The Can't verify update error when installed via Recovery indicates that the bootloader is locked and the firmware signature does not match the region of the device, in which case you can not do without unlocking BL.
💡
If the phone is constantly rebooting or warming after firmware, don’t panic. Try to do a full reset (Wipe Data) through Recovery or reflash the device clean with the mandatory cleaning of all partitions.
