MIUI and its modern evolution HyperOS are complex software packages that require periodic maintenance. Gadget owners often face the need to specify the exact build number, especially when software failures occur or before flashing the device, and understanding the current software configuration is the first step to managing the device properly.
Software information is not limited to Android version numbers: it is a set of data that includes the kernel version, build date, firmware type (Global, China, EEA) and security patch level. Correct identification of these parameters avoids installing incompatible updates and helps technicians diagnose malfunctions faster.
In this article, we will take a look at all the available methods for obtaining this information, from standard menus to advanced debugging tools, learn how to distinguish between firmware types and understand why sometimes the version number in the settings can differ from the real system build.
Checking through the standard settings menu
The most obvious and affordable way to find out what you're looking for is through the operating system's standardized interface, and the path to information is standardized for most of the brand's devices, although item names may vary slightly depending on the shell version, so you'll need to open the Settings app and find the About Phone section.
The screen that opens displays a large digital label, such as 14.0.5 or 8.0.11. However, this is only a marketing designation. To get detailed technical information, you need to do a series of sequential actions. Touch the area with the MIUI or HyperOS logo several times in a row until the interface changes.
Once the hidden menu is activated, an extended page with a detailed specification will open, and here you will see the MIUI version line, which contains the full build code, which is the code used to search for firmware files on official resources, and in some cases, the system may suggest checking for updates as soon as this screen is opened.
💡
Write down the full version code (e.g., V14.0.3.0.TNLMIXM) before any manipulations, which will help to quickly return the device to its original state in case of an error.
Decoding the code of the firmware version
The resulting alphanumeric code may seem like a set of random characters, but in fact it carries structured information about the origin and characteristics of the software. By analyzing the string asymbolically, you can determine the region for which the device is intended and the type of operating system installed.
The first characters usually indicate the Android version or the number of the main development branch, followed by an alphabetic index indicating the processor platform (for example, M for MediaTek, S for Snapdragon), and the region codes such as EU (Europe), RU (Russia/CIS), IN (India) or GL (Global Version) complete the line.
- 🌍 MI — Global version for the international market (Global Stable)
- 🇪🇺 EU — Version for the European Union countries
- 🇷🇺 RU — Localized version for Russia and CIS countries
- 🇨🇳 CN — Chinese version (China Stable)
It is important to understand the difference between stable and test builds: Stable versions are labeled Stable and are designed for everyday use by ordinary users. Test versions, known as Developer or Beta, are updated weekly and may contain bugs, but offer access to the latest features before others.
What do the letters at the end of the code mean?
Using the Engineering Menu for Diagnostics
For users who need more technical information, there is an engineering menu that is designed for developers and service engineers, but is also available to ordinary smartphone owners through a special set of commands in the call.
To get into the test menu, open the Phone app and type ##64663##. On some models or in certain regions, the code may differ, such as ##4636##. Once you enter the last digit, the menu will open automatically, without the need to press the call button.
⚠️ Warning: The engineering menu contains critical radio module and sensor settings, and changing parameters at random can lead to loss of communication or malfunction of equipment.
In the list that opens, select Version or Hardware info, which displays not only the firmware version, but also the serial numbers of components: display, touchscreen, cameras and memory modules, and this data is especially useful when checking the device for replacement of original parts with analogues.
Data acquisition via ADB and Fastboot
If the operating system does not boot or the screen does not respond to touches, you can get information through the computer using Fastboot mode or ADB debugging.
To work, you'll need to install ADB drivers on your PC and connect your smartphone with a cable. After you put your device into debugging mode (via the Developer Menu), run a command at the terminal and ask the system for the full name of the current build.
adb shell getprop ro.build.display.idYou will get the exact string of build ID. If the device is in bootloader mode (a mode with a rabbit fixing a robot), connect it to your PC and type in the command fastboot getvar all. In the output, among the many lines, find the version-baseband or version-bootloader field, which will also give you an understanding of the low-level version of the software.
The table of correspondence of versions of Android and MIUI
There is often confusion between the MIUI/HyperOS shell version and the Android underlying version. The shell can be updated independently of the Android kernel, although major releases usually go together. Below is a matching table for current versions.
| MIUI/HyperOS version | Basic version of Android | Type of assembly | Year of release |
|---|---|---|---|
| HyperOS 1.0 | Android 14 | Stable / Beta | 2023-2026 |
| MIUI 14 | Android 13 / 12 | Stable | 2022-2023 |
| MIUI 13 | Android 12 / 11 | Stable | 2021-2022 |
| MIUI 12.5 | Android 11 / 10 | Stable / Enhanced | 2021 |
| MIUI 12 | Android 11 / 10 | Stable | 2020 |
It is worth noting that on devices of different years of release, the same version of the shell can be based on different versions of Android. For example, MIUI 12 for the old flagship could come on Android 10, while for the new one – immediately on Android 11. So always check the basic platform if you plan to install custom recoveries or modifications.
💡
The matching of Android and MIUI versions is not guaranteed: old hardware often gets new shells without updating the Android kernel.
Verification of firmware on Xiaomi routers
Xiaomi’s ecosystem includes not only smartphones, but also networking equipment. The Mi Router and Redmi Router series also require periodic firmware updates to ensure network security.
To get information, you need to connect to the router's web interface. Type in the browser address bar. IP-Gateway address, usually 192.168.31.1 or miwifi.com. After authorization (the default password is often listed on the sticker at the bottom of the device), go to Settings or Settings.
- 📡 Find Status or Status in the side menu.
- 📄 The System Information block will show the current version of firmware.
- ⬆️ There is usually a button near the check updates button.
Alternatively, use the Mi Home mobile app. Add the router to the device list, click on its icon, and select router Settings. The current version number will be displayed at the top of the screen or in the About section. The update through the app is often more stable than through the web interface.
⚠️ Note: When updating the router, it is strictly not recommended to interrupt the power. Failure of recording in flash memory can turn the device into a "brick", the recovery of which is possible only through the use of a computer. UART-console.
