Owning a smartphone from Xiaomi, brought from China, often involves a number of inconveniences for the average user. the lack of pre-installed services Google Play, the presence of Chinese in the interface and specific notifications can turn the use of a modern gadget into a real quest. That is why the question of how to move from Chinese firmware to global, remains one of the most popular among owners of equipment of this brand.
The process of changing the regional version of the software requires careful and strict follow-up to the instructions, as any errors can lead to the failure of the device. In this article, we will discuss in detail all the stages of preparation, the necessary tools and the sequence of actions for the successful installation of the Global ROM. You will learn about the risks, features of unlocking the bootloader and methods of restoring the system in the event of unforeseen failures.
Before you start taking action, you need to realize that flashing is an interference with the program code of the device. Changing the regional version from CN to Global is only possible with a complete cleanup of all data and unlocked bootloader.
Key differences between Chinese and global versions of MIUI
The main difference between the versions lies not only in the interface language, but also in the set of pre-installed applications and system services. Chinese firmware (CN ROM) is optimized for local services such as Baidu and WeChat, and is deprived of licensed Google products. The global version (Global ROM) contains a full package of Google Mobile Services, which is critical for the work of most familiar applications, including maps, mail and the Play Market store.
Global firmware versions often include a wider range of LTE and 5G bands relevant to Europe and the CIS. Chinese versions may not support certain frequencies (for example, Band 20), which will lead to a deterioration in the quality of signal reception in some regions.
It is important to note the difference in the availability of system advertising: in Chinese builds, advertising is built deeper into the system and is focused on the Chinese market, whereas in global versions, its number can often be adjusted or it is not in system applications.
| Characteristics | Chinese version (CN) | Global version (Global) |
|---|---|---|
| Google services | Not present (requires manual installation) | Pre-installed and integrated |
| Interface languages | Chinese, English | Full localization (including Russian) |
| LTE/5G frequencies | Optimized for China | Support for international standards |
| System applications | Chinese services (Baidu, Mi Video CN) | Google, YouTube, Maps, Duo |
Preparation of the device and necessary tools
Success of the operation 90% It depends on the quality of the training, USB-cable with high-quality insulation (preferably original or certified) MFi/USB-IF) Before any manipulations, you need to create a full backup of all important data, since the internal memory will be completely formatted during the flashing process.
You should install the current ADB and Fastboot drivers on your computer, as well as the SDK Platform Tools platform. Without these components, your computer will not be able to properly interact with your phone in boot mode. It is also recommended to download the official Mi Flash Tool utility from the developer's website, which will be used to directly record the firmware image.
☑️ Checklist for reflashing preparation
Special attention should be paid to the choice of firmware file. You need an archive marked Fastboot, not Recovery. Fastboot files usually have the extension.tgz and weigh much more (3-5 GB), whereas Recovery versions have the extension.zip. Using the wrong file type in the Mi Flash Tool will lead to a process error.
⚠️ Note: Using firmware from third-party models or designed for other regions (e.g. Indian instead of European) may result in hardware locking of the device. Always check the code name of the model (e.g. davinci for Redmi). K20) pre-download.
The procedure for unlocking the bootloader (Bootloader)
The hardest and longest step is unlocking the bootloader, and Xiaomi has introduced this security measure, so you can't just flash the device. You need a Mi Account that must be linked to the device. Once you're tied, you need to apply for unlocking through the special Mi Unlock app.
After submitting an application, the system may require you to wait from 7 to 168 hours (usually 7 days). During this time, you can not leave the Mi acca on the device and reset the settings. After the wait timer expires, holding the power and volume buttons, go to Fastboot mode (image of a hare fixing an android) and connect the phone to the PC.
What to do if the timer is not going?
When the waiting time is up, we run the Mi Unlock utility on the computer, enter the same account that was used on the phone, and if all the conditions are met, the program will allow you to unlock the bootloader, and the process will take a few seconds, after which the phone will restart, and all the data will be deleted.
Installation of global firmware through Fastboot
After successful unlocking, you can start directly to the installation of Global. ROM. Unpack the downloaded archive with firmware in the root folder of the disk or any convenient place, as long as the path to the folder does not contain Cyrillic characters. flash_all.bat (or flash_all_lock.bat, If you want to close the bootloader again, although it is rarely required for the global version immediately) from the unpacked folder.
If you use the Mi Flash Tool GUI, press the refresh button to detect the connected device. Make sure the list shows the serial number of the phone. In the bottom menu, select clean all mode to avoid file system conflicts. Pressing the flash button will start the firmware process.

Under no circumstances, turn off the cable or interrupt the power supply of the computer. Once the procedure is complete, the phone will automatically restart. The first boot can take up to 10-15 minutes.
⚠️ Warning: If there is an error in the firmware process (e.g., red text in the log), don't panic. USB-cable, switch port on motherboard (use ports) USB 2.0) or start the procedure on behalf of the administrator.
Solving common mistakes and problems
One common problem is the “Miss matching image and device” error, which means a firmware mismatch in the device model. This happens if you try to flash the Redmi Note 8 Pro version to a regular Redmi Note 8. Carefully check the device codename in Fastboot mode and in the firmware file name.
Another common difficulty is hanging on the MI logo (Bootloop). If after firmware the phone is endlessly rebooted, try resetting via Recovery Mode. To do this, press the power and volume buttons. From the reclaim menu, select Wipe Data -> Wipe All Data. If this does not help, you may need to re-run the firmware with a choice of clean all and lock option.
💡
Use it. USB-a hub without external power, or connect the phone directly to the ports on the back of the system unit. Front ports and long extension cables often give insufficient voltage, causing a connection to break at a critical point in data recording.
Users also face the problem of not connecting after flashing, which may be due to incompatibility of the radio module, which may require flashing the modem separately or finding a specific firmware assembly adapted to your region, but this is rare when using official global firmware.
