Ownership of a Xiaomi smartphone brought from China is often marred by the lack of familiar Google services and the presence of Chinese in the interface. Users buying such devices for the sake of saving or accessing exclusive models inevitably face the need to install global firmware, a process that allows not only to Russify the menu, but also to access Google Play, banking applications and correct notifications.
The software replacement procedure requires care and preparation, as errors at any stage can lead to the failure of the gadget. Current methods allow you to perform the firmware relatively safely using the official tools of the manufacturer. However, it is important to understand that you take responsibility for the result, and any actions with system files are always fraught with risks.
In this article, we will go through all the steps from unlocking the bootloader to the final setup, learn about the differences between the Recovery and Fastboot versions, and get answers to frequently asked questions. Installation of global firmware in the Chinese region is possible only after the full unlock of the bootloader (Unlock Bootloader), without this step, further action is impossible.
The main differences between CN ROM and the Global version
Before you start technical manipulation, you need to clearly understand the differences between the original Chinese firmware (China ROM) and the international version (Global ROM), the Chinese version is optimized for local services, it does not have pre-installed Google applications, and the notification system works on aggressive energy saving algorithms, which often leads to delayed messages in messengers.
Global firmware includes a full package of services Google Mobile Services, support for many languages, including Russian, and adapted to work with European and American frequencies. In addition, the Global version has changed the set of standard applications, using standard maps, browser and cloud storage, familiar to the international user.
It is important to note that after flashing, some features specific to the region may become nuanced, such as the Themes app may not work properly, and some VoLTE system calls may require additional customization.
| Characteristics | Chinese version (CN) | Global version (Global) |
|---|---|---|
| Interface languages | Chinese, English | Multilingual (including Russian) |
| Google services | Not present (installation required) | Pre-installed |
| Communication frequencies (Bands) | Optimized for China | Support for international standards |
| Advertising in the system | Present in standard applications | Minimum or absent |
Preparing the device and computer for flashing
The success of the operation depends on 90% of the quality of preparation. You will need a computer with Windows, because the main tools for working with the bootloader and firmware work best in this environment. Using virtual machines or macOS is possible, but may require additional driver settings.
Make sure to back up all important data. The process of unlocking the bootloader and then flashing will result in complete deletion of information from the internal storage of the smartphone. Photos, contacts and documents are better copied in advance to a cloud server or external hard drive.
☑️ Checklist of preparations
Use an original or quality USB cable to connect your smartphone. Cheap charging cables often don’t support data transfer, which can interrupt the firmware process at the most inopportune time. Also make sure there is enough free space on your computer’s drive to unpack system image files.
Unlock Bootloader (Unlock Bootloader)
The most difficult and lengthy step is unlocking the bootloader. Bootloader is a program that runs before the operating system boots and checks the digital signature of the software being downloaded. Chinese versions of Xiaomi come with a locked bootloader that prohibits the installation of unofficial or regional firmware.
First, link your Mi Account to your device. Go to your smartphone settings, select About Phone, and click on the MIUI (or HyperOS) version several times to activate the developer menu. Next, in the advanced settings, find Mi Unlock Status and activate it by linking your current account to your device.
⚠️ Note: Once an account is tied, the system will require you to wait 7 to 168 hours (depending on account activity and region) before unlocking.
After the waiting time, connect your phone to your PC in Fastboot mode. To do this, you need to pinch the device that is turned off simultaneously with power and volume buttons until the image of a hare repairing an android appears on the screen. Then run the Mi Unlock Tool utility on your computer and follow the instructions on the screen.
What if Mi Unlock doesn’t see your phone?
Firmware type: Recovery ROM vs. Fastboot ROM
When downloading a system image, you will encounter two main file types: Recovery and Fastboot. Understanding the difference between them is critical, as the methods of installing them are radically different. Recovery ROM has the.zip extension and is designed to be installed via a recovery menu or built-in updater.
Fastboot ROM has a.tgz extension and contains a complete image of all partitions of the system. This is the type of firmware required to move between regions (from CN to Global). Fastboot ROM can only be installed via a computer using the command line or graphical shells.
- 📦 Recovery ROM: Updates only system files without erasing user data (when updating within the region), but does not allow you to change the region.
- 🛠️ Fastboot ROM: Complete system reinstallation, requires an unlocked bootloader, necessarily erases all data, allows you to change the region.
- 🔄 OTA: Automatic updates “over the air” only work if the current firmware matches the region with the update server.
For our mission to turn a Chinese into a global, you need a Fastboot ROM with an index of the MI region (Global) or the EU (Europe), if you prefer a European build, download files only from proven resources, such as the official website miui.com or authoritative archives like xiaomirom.com.
Installation of global firmware through Fastboot
After successfully unlocking the bootloader and downloading the Fastboot file ROM, You can start the installation. Unpack the firmware archive at the root of the C disk so that the path to the folder is Cyrillic-free and short, for example. C:\rom\. There must be a file inside the folder. flash_all.bat (Windows).
Put your smartphone in Fastboot mode (power buttons and volume down) and connect it to your computer. Open the file flash_all.bat. The script will automatically run the necessary commands. ADB And Fastboot, which erases old partitions and writes a new system, and the phone's screen will flash the Android logo or lines of code.
💡
Use the team. flash_all_except_storage.bat, if you want to try to save files on the internal drive, but for stable operation after the change of region is strongly recommended a complete cleanup (flash_all.bat).
The process can take from 5 to 15 minutes. At this time, you should not turn off the cable. USB If the process is stuck at a certain percentage for more than 10 minutes, you may need to reinstall the drivers or replace them. USB-port.
⚠️ Warning: If during firmware, the smartphone screen went out and the device stopped responding to the buttons, do not panic. 15-20 If the phone is entering Recovery mode, repeat the firmware procedure.
Primary adjustment and solution of typical problems
Once installed successfully, the first boot can take up to 10 minutes longer than usual, which is normal because it optimizes applications and creates new configuration files, and when you see the welcome screen, select the language you want and start setting up.
One of the common problems after flashing is the lack of Google Play Protect certification, which is because global firmware is installed on a device with a Chinese serial number.This doesn’t pose a problem for most users, but some banking applications may require additional security manipulation.
It’s also worth checking out NFC and contactless payment.In some cases, you need to clear the data of the Google Pay app or add the device to the list of trusted ones through Magisk if you plan to use root rights.However, it’s easy to log into your Google account for standard use.
💡
Successful installation of global firmware makes the device a full-fledged international gadget, but deprives the warranty of official service centers in your region.
