Xiaomi smartphone owners often face a situation where a device brought from China or bought from merchants operates in a region-specific mode. MIUI HyperOS dictates not only the default interface language, but also a set of pre-installed applications, system refresh rates, and even available features such as call recording or sign-up themes. Users in Russia and CIS countries often look for a way to reset the region or completely remove the link to China to turn the region into a new one. CN-Full version of the Global ROM.
The process of changing regional settings can range from simply switching a menu item to complex flashing of the device to unlock the bootloader. Wrong actions can lead to the phone no longer catching the 4G/5G network or turning into a “brick.” In this article, we will discuss all the safe methods of adapting the device to our latitudes, including working with the engineering menu and official utilities.
Before you start taking any drastic measures, you need to understand what you're not happy with in your current configuration. Often, the problem is solved with less painful methods than full flashing. It's important to distinguish between the software setting of the region in the menu and the deep system code sewn into the persist or modem section. We'll look at both cases so you can choose the best way to solve the problem.
Why the region is important and what it affects MIUI
Regional anchoring is not just a flag picture on a lock screen; it's a comprehensive setup of the Android operating system with a MIUI shell that determines how the telecommunications modules work. When you change country, the frequency ranges supported by the modem change, which directly affects communication quality. If you use the Chinese version (CN Version) in Europe or Russia, the absence of some Band 20 frequencies can lead to a loss of signal in buildings.
In addition, the country code regulates the operation of Google system services and local services Xiaomi. Chinese firmware default services no Google Play, and instead installed the store GetApps and Chinese analogues of popular applications. Changing the region to “India” or “Global” often allows you to activate the installation of Google services without complex manipulation, although in recent versions of HyperOS this process has become more stringent.
⚠️ Warning: Forced region change through the engineering menu on new models with Snapdragon 8 Gen 2 processors and later may cause a lock on camera functions or NFC due to the integrity of the system.
Advertising in system applications also depends on the region chosen. In some countries, intrusive marketing is prohibited by law, so switching to the appropriate country code (for example, Singapore or India in the past) allowed you to get rid of banner ads in standard utilities. However, with the release of new versions of the software, Xiaomi began to unify this experience, and simply changing the settings often becomes not enough.
Programmatic change of region in settings
The easiest and safest way to change the country code is to use the system’s regular tools, which do not require root rights, unlock the bootloader or connect to a computer, but are suitable for cases where you just need to change the displayed region for applications or content to work, but do not require a deep modem overhaul.
To do this, go to your device's settings menu. Find the Additional or Advanced Settings section, then select Region. From the list that opens, select the country you want, such as Russia, Ukraine, or United States. The system may need to reboot to apply the changes. Once enabled, the interface and some system applications adapt to the selected standard.
But you have to understand the limitations of this method. It doesn't change the basic firmware. If you have a Chinese version (CN ROM), changing the region in the settings won't add Russian to the menu or remove Chinese software. Moreover, changing the region frequently can temporarily block the ability to install themes from the official store.
☑️ Checking before changing the region
In some cases, especially on older versions of MIUI, changing the region through settings will activate hidden features. For example, choosing India previously opened the possibility of recording calls with notification of the interlocutor, and choosing the USA changed the format of the date and time. These features now often depend on the version of the shell, but it is worth trying if you lack a specific option.
Using an engineering menu to reset code
For more advanced users who want to change the modem's depth settings, an engineering menu is available, which allows you to control the parameters of the radio module, including forced country code change (CSC), which is effective when a standard change of region in the settings does not give the desired result or is blocked by the manufacturer.
To get into the engineering menu, open the Phone app and enter a special code. For most Xiaomi devices, the code ##4636## is current. If the menu does not open, perhaps your model requires installing a special activator application or using it. ADB-Select Phone Information from the menu.
In the phone information section, find the Set Preferred Network Type field. Although it is a choice of network type, in some firmware modifications here or in adjacent menus (via Menu -> Secret Code, you can find Region Change. Be very careful: choosing the wrong code can cause the phone to stop seeing. SIM-map.
| Parameter | Description | Risk |
|---|---|---|
| RU | Russia (optimization for local networks) | Low. |
| EU | Europe (Limiting Wi-Fi Power) | Medium. |
| CN | China (complete functionality, but not Google) | High (for global versions) |
| GLOBAL | Global (universal) | Low. |
⚠️ Warning: Changing the settings in the engineering menu (#4636###) on devices with MediaTek processors may require you to enter a password. IMEI.
What if the code doesn't work?
Firmware change: Global vs China ROM
If the software methods don't help remove the Chinese country code and the built-in software, the only reliable solution is firmware reflash, and there are two main ways: installing Global ROM on top of Chinese or Cross-flash, the first method is simpler and safer, the second requires an unlocked bootloader.
Global firmware already contains the required region code, Russian language and Google services out of the box. It is often enough to download a file from the official MIUI Download website and update via the Select Firmware File menu in Recovery mode. However, if you try to switch from CN to Global, the system will give a version check error.
This requires unlocking the bootloader through the official Mi Unlock Tool, a process that takes 7 to 16 days to complete, and once unlocked, you can completely clear the device’s memory and install any version of the software that matches your region, removing the country code that you don’t need forever.
It is important to keep in mind the firmware types: Stable (stable) and Developer (developer). For everyday use, only a stable version is recommended. Also pay attention to the firmware type: Fastboot (for installation via a PC with a full reset) or Recovery (for updating without loss of data, if the versions are compatible).
💡
Always download firmware only from official resources or trusted forums (such as 4PDA or XDA) Files from questionable sources may contain malicious code or be modified, leading to data leakage.
Removing regional restrictions through ADB
For users who don’t want to unlock the bootloader but want to remove some restrictions, there is a method of using ADB (Android Debug Bridge), which allows you to send commands to the system directly, bypassing the standard interface, and you can use it to disable regional checks for installing themes or remove system applications that are tied to the country.
To get started, you need to enable USB Debugging in the Developer menu. Then connect the phone to your computer and start the ADB console. The adb shell command will open access to the device's command line. Next, you can use commands to delete packets, such as pm uninstall -k --user 0 com.miui.global.packageinstaller (the name of the package may vary).
adb shell pm uninstall -k --user 0 com.miui.misystem
adb shell pm uninstall -k --user 0 com.android.browserThis method doesn't change the region code in the modem, but it does clean up the system of any extra debris that often comes in addition to certain regional versions. Be careful: removing system components can cause the device to run in an unstable way. Always check the name of the package before removing it.
There are also special scripts (e.g. Xiaomi ADB/Fastboot Tools) that automate this process. They provide a graphical interface to select the regions and applications that deaktivirovat needs. It's a great way to adapt a Chinese phone to global use without flashing it.
Communications and IMEI issues after region change
One of the most serious problems users face after a failed attempt to remove the country code or flashing is the loss of a home. IMEI. In modern smartphones Xiaomi identifiers IMEI stored in a secure partition persist or EFS. Incorrect interference with these sections (for example, when using dubious patches to change the region) leads to the fact that modem stops seeing. SIM-map.
Symptoms of the problem: in the status bar, instead of the signal level, a cross or the inscription “No network” is displayed, in the IMEI settings, it is displayed as 0 or null. It is almost impossible to restore IMEI software on new devices without factory backups (QCN files), which are unique to each device.
⚠️ Note: If the region has been changed IMEI, Do not try to do a Wipe Data reset - this will completely destroy the possibility of recovery.
There are also potential problems with VoLTE and VoWiFi, which are tightly tied to operator certificates and country code, and when you install global firmware on a Chinese device, the function may disappear, the solution being to edit the modem configuration files or use engineering codes to activate if the operator supports gray devices.
💡
The most reliable way to get a clean system without Chinese code is to officially unlock the bootloader and install Global Stable firmware via Fastboot.
