How to check which firmware on Xiaomi: a detailed guide

Owning a Xiaomi smartphone often puts users in a position to understand software, especially when it comes to getting updates or installing apps. Knowing the exact version of the operating system and the type of MIUI or HyperOS shell installed is a critical parameter for any device owner, which helps them understand what features are available, whether your region’s language is supported, and where the next security patches will come from.

Many users buy devices on popular marketplaces and find that the Chinese language or global version of the phone is unstable. Determining the type of firmware (CN, Global, EEA, India) is the first step to solving 90% of software problems. In this article, we will look in detail where to look for hidden information about the system, how to decrypt version codes and how different regional builds differ from each other.

Understanding the differences between software versions will allow you to avoid installing incompatible software and properly configure the gadget. We will look at both the standard methods through the interface, and more advanced methods through the engineering menu and computer utilities.

Standard way to check through the settings menu

The most obvious and accessible method for every smartphone owner is to use the built-in interface of the system. You need to open the Settings app and scroll down to the bottom, where the "A" item is usually located, and that's where the basic information about the device model, the amount of memory and, most importantly, the software version is contained.

Click on the line that shows the MIUI version (e.g. MIUI 14.0.5). Often a single click is not enough: the system can show a pop-up with the logo, but will not display the detail. You need to quickly click on this line 5-7 times in a row until there is an additional menu or a message that you became a developer. In some cases, detailed information is displayed immediately below the main version.

Note the line MIUI for Android, which is where the letter code that points to the region is hidden. For example, the entry 14.0.3.0.TNLMIXM tells a lot to an experienced user, and we'll break it down in the next sections, because it's the key to understanding the origin of your device.

💡

If nothing happens when you click on the firmware version, try going to the All Options menu (three dots in the corner of the screen) and selecting the MIUI version there.

It's important to understand that the standard menu only shows the current active version. If you've been searching your phone at a service center, it can display information that the wizard has sewn in there, even if it doesn't match the hardware of the device. So always check it against the box or check when you buy a new gage.

Decoding the code of the firmware version Xiaomi

The firmware version code is not just a random character set, but a strictly structured string that carries encoded information about the region, model and development stage. Let's take the example of V14.0.5.0.TNLMIXM code by segment, so you can analyze any software yourself.

The first letter V represents the version type: V is stable, X is weekly (Developer/Weekly), the next number (14.0.5.0) is the shell version number, followed by the letter for Android version: T is Android 13, S is Android 12, R is Android 11. The dot is followed by the device model code (e.g., NL for Redmi Note 12).

⚠️ Note: If the code version after the device model are letters CN (for example,...NLCNXM), So you're looking at the Chinese version of the firmware, and these devices may not have Google's default services, and they may also have Chinese software that can't be removed by standard methods.

The last two letters in the code indicate the region of release:

• 🌍 MI — Global (Global version for the whole world except China, Europe and India).
• 🇪🇺 EU — Europe (European version, often differs in communication frequencies and pre-installed applications).
• 🇮🇳 IN — India (Indian version, can have specific camera settings and pre-installed local services).
• 🇷🇺 RU — Russian version, now rare, mostly on older models).

Understanding this structure allows you to instantly determine whether the seller has confused the global version with the Chinese one. If you ordered a phone from abroad and see a CN in the code, then you have sold a device for the domestic market of China, even if the menu is translated into Russian (which is often done by flashing).

Use of the engineering menu and USSD-code

There is an engineering menu to get more technical information hidden from the average user, and it can be accessed in several ways, and this is often required to verify the authenticity of the screen, battery or detailed firmware status. The easiest method is to enter a special USSD-code in the appendix "Phone».

Dial ##64663##. If the device supports this feature, the CIT menu will open, where you can check the operation of all modules, but we are interested in the version of the software. In some models, the code ##4636## opens the testing menu, where you can see more technical information about the build in the Device information section.

It is worth noting that on new versions of HyperOS and recent MIUI updates, access to the engineering menu through dialing can be blocked for security reasons, in which case the system will simply reset the challenge or nothing happens.

There is also code ##8375##, which in some regions displays detailed version information in a pop-up window, but its performance is highly dependent on regional firmware and the specific phone model.

Checking the firmware type through a computer and ADB

If the interface of the phone is damaged or you want to get the most accurate data without unnecessary clicks, you can use a computer. ADB (Android Debug Bridge and connect your smartphone USB-This method is considered the most reliable for professionals.

After connecting and enabling debugging over USB (in the Developer Menu), open the command line on your PC. Enter the command:

adb shell getprop ro.miui.ui.version.name

This command will return the name of the shell version. To get the full firmware code, use the command:

adb shell getprop ro.build.display.id

The result is a precise version string that can be analyzed using the diagram described above, which is good because it reads data directly from Android system properties, bypassing the graphics shell, which can be modified.

Using the command line also allows you to check the hash amount of system files if you have any suspicions about firmware integrity, although this already requires a deeper knowledge of Linux-like systems.

Comparison of regions: Global, CN, EEA and others

The differences between regional versions of Xiaomi firmware can be significant and affect everyday use. The Global version usually lacks Chinese software, has Google services built in, and supports many languages, including Russian.

The Chinese version (CN) is often updated earlier than others, optimized for local services, has an aggressive power saving system that can block notifications from instant messengers, and does not have Google Play preinstalled (although it can be installed). The security menu on Chinese firmware often features ads that are difficult to disable without dancing with a diamond.

The European version (EEA) is characterized by strict compliance with GDPR, the presence of privacy warnings at the first turn on and sometimes differences in the supported frequencies of LTE/5G. The Indian version (IN) can have pre-installed applications of local banks and marketplaces, as well as specific camera settings tailored to the local flavor.

The choice between these versions depends on your needs. If you want stability and out of the box work, go for Global. If you're an enthusiast and want the latest features first, CN, but be prepared to set up.

Frequent problems and ways to solve them

One common problem is when the phone stops receiving updates, which often happens if you change the region of the device in the settings or if the phone has installed firmware from another region on top of the stock without unlocking the bootloader. The system sees a region mismatch SIM-maps and software and block OTA-update.

⚠️ Note: Attempt to force the installation of firmware from another region (for example, Global on the Internet) CN) Without unlocking the bootloader, it can lead to a device lock (Hard Brick) or data loss.Always check compatibility before firmware.

If you find that you have a Chinese version and you want a global one, don’t panic. Many models can unlock the bootloader (requires a wait of 7-168 hours and a Mi Account) and reflash the device through the Mi Flash Tool.

Users also often experience a “failed to check the update” error, which may be due to unstable internet or temporary problems on Xiaomi servers, in which case cleaning the cache of the Update app or waiting for several hours helps.
