Owners of Xiaomi, Redmi and POCO smartphones often face the need to clarify the exact version of the installed operating system, which may be necessary when searching for bug fixes, when applying for technical support or before manually installing updates. Understanding the numbering structure of MIUI and HyperOS avoids installing incompatible files, which is critical for the stability of the device.
Software information is hidden in the back of the menu, but is available in a few simple steps. In this article, we will explore all possible methods for identifying builds, decipher complex version codes, and explain how regional modifications differ, learn how to distinguish between global and Chinese versions, and understand why the firmware release date is more important than just the version number.
Incorrect interpretation of the system data can lead to an attempt to flash the phone to an older version, which sometimes causes errors when downloading. So Xiaomi has several layers of protection and information for the user. Let's figure out where to look for this data and how to read it correctly, so that you don't get confused in the numbers.
Basic verification through the settings menu
The most obvious and reliable way to get information about the current state of the system is through the standard settings menu, which displays the basic data that a regular user needs to understand the relevance of his device. To get there, open the Settings app and find the About phone item, which is usually located at the top of the list or in the Main section.
In the window that opens, you'll see a large digit for the shell version, like MIUI 14 or HyperOS 1.0. However, for peer review, this is not enough. You need to click on the MIUI or HyperOS logo string several times (usually 3-5 times) to activate the hidden menu of advanced information, and that's where the full line of the version, including the region and the build date, is hidden.
Once the additional menu is activated, the screen will split into two parts or a pop-up with detailed data will appear. Here, it is important to pay attention to the field of the MIUI Version, which contains an alphanumeric code, which is a unique identifier of a particular build and tells us about the region for which it is intended and the date of its release.
☑️ Verification of the relevance of the software
It's worth noting that newer versions of the shell may have slightly different interfaces, but the logic remains the same. If you don't see the full version right away, try tapping on the "MIUI Version" line before the extra window comes along. This is standard procedure for all the brand's devices, from budget Redmis to flagship Mis.
Decoding the code of the firmware version
The version string you saw after activating the hidden menu looks like a set of characters, for example, V14.0.3.0.TKGMIXM. For an inexperienced user, these are just numbers, but for a specialist, this is an accurate map of the origin of the software. Let’s analyze the structure of this code, since understanding each character helps determine the compatibility of the firmware with your device.
The first letter "V" means that it is a stable version (Stable). If there was an "X", it would indicate a test build (Developer or Beta), which contains experimental features, but may not work well, followed by the numbers of the main version of Android or MIUI, followed by the letter code of the platform.
What do the letters in the platform code mean?
The last three letters in the code point to a region, a critical parameter that is often ignored. The global version is labeled MI (Global), the European version is labeled EU, the Russian version is labeled RU, and the Chinese version is labeled CN. Trying to install the firmware of one region on another region's device without unlocking the bootloader is impossible and can lead to a brick.
💡
When searching for firmware on third-party resources, always check the last three letters of the version code. CN-Firmware on the global apparatus without reflashing the entire region is impossible by standard methods.
The last two digits in front of a region often indicate a month and a year, although the format can vary depending on the version of the shell, and understanding this structure allows you to instantly determine whether your version is newer than the one you downloaded from the Internet, even if the version numbers look similar.
Use of engineering menus and codes
For deeper diagnostics beyond standard settings, there is an engineering menu that is accessed through a special set of commands in the Phone app, which allows you to access hidden parts of the system that contain technical information about the status of the modules and the version of the basic components.
One of the most useful commands for checking detailed information is to enter code ##6484##. This code opens the engineering menu, where you can check not only the software version, but also the operability of all sensors, screens and communication modules. In the Version or Hardware Info section, you can often find the numbers of the base radio modules and bootloader.
Another useful code is ##4636##. It opens the testing menu, where you can see more technical connection data and sometimes a version of the modem's basic software in the Phone Information section, which is useful if you're having communication issues and you want to make sure the drivers are up to date.
💡
The engineering codes do not work on all devices; in newer versions of MIUI and HyperOS, access to some partitions may be restricted by the manufacturer for security reasons.
These codes are safe to use if you're just looking at the information, but be careful: changing the settings in the engineering menu without understanding their purpose can disrupt the radio module or screen calibration, and it's recommended that you read the data, but not change the values in the input fields.
Definition of ROM type: Global, CN, EU
One of the most important aspects of owning a Xiaomi device is understanding the differences between firmware types (CN ROM) They're just a little bit cheaper, and then they're surprised that there's no Russian language or Google services. ROM It starts with the version code analysis mentioned above.
The global version (Global) is designed for the international market. It has the MI region code at the end of the version line, contains multilingual support (including Russian), pre-installed Google services and usually operates more stable in our latitudes due to the configured communication frequencies. The European version (EEA) is almost identical to the global one, but has EUX or EU code and stricter GDPR compliance.
The Chinese version (CN) has the CN code at the end, often lacking Russian (English and Chinese only), no built-in Google services (although they can be installed manually), and specific Chinese applications. In addition, Chinese firmware may have restrictions on the operation of some 4G frequencies (Band 7, Band 20), which affects the quality of communication in Europe and the CIS.
There are custom builds, like Xiaomi.eu. This is not the official firmware, but a modified version of Chinese software that has Russian embedded, removed ads and added Google services. The version bar of such builds usually contains the word "eu" or "weekly." They are popular among enthusiasts, but require an unlocked bootloader to install.
Comparison of MIUI and HyperOS versions
Xiaomi is currently moving from MIUI to the new HyperOS platform, a move that marks a change in the numbering and structure of the software. If you own a new device or have recently upgraded, you may see a version starting with OS1.0, which matches Android 14 and the HyperOS base.
The main difference in version verification is that HyperOS uses a single ecosystem numbering. In MIUI, the version was often tied to the Android version (e.g. MIUI 12 on Android 10, MIUI 13 on Android 11), although not always linear. In HyperOS, the numbering has become more unified, and the OS version can be updated independently of the major version of Android in some cases.
When checking for updates on HyperOS devices, the interface may look more minimalistic, but the principle of getting the full version remains the same – taps by logo. It is important to keep an eye on the news, since older devices may not get an update to HyperOS, staying on MIUI, and for them version verification will be done according to the old rules.
| Characteristics | MIUI (Old) | HyperOS (New) | Meaning to the user |
|---|---|---|---|
| Numbering | MIUI 12, 13, 14 | HyperOS 1.0, 2.0 | HyperOS has a single numbering for all devices |
| Basis | Android + AOSP | Android + Xiaomi Vela | HyperOS is lighter and faster on weak iron |
| Size | More severe. | Optimized (easier) | Upgrading to HyperOS could free up memory |
| Ecosystem | Smartphone + Tablet | Man + Auto + Home + Home + Man + Man + Car + Home | HyperOS better connects Xiaomi equipment with each other |
Solving Problems with Version Determination
Sometimes users are faced with a situation where the version number in the menu does not change after the update, or incorrect information is displayed. This can be caused by caching data in the settings application or errors in the process. OTA-Update over the air In such cases, simply restarting the device often solves the display problem.
If you have manually updated and the number is still old, it may be that the firmware file was damaged during download or did not match the device model, the system may have rolled back the changes or not fully implemented them, in which case it is recommended to check the version through the engineering menu or use the software. ADB-commands to obtain accurate data from the system.
⚠️ Note: If the version number has changed after the update, but the phone is unstable (heats, discharges quickly), there may be a data conflict. In this situation, a full reset (Wipe Data) after the update often helps, but this will delete all your files.
For advanced users, there is a way to check the version through a computer using the ADB utility (Android Debug Bridge), connecting the phone to the PC in USB debugging mode, you can enter the adb shell getprop ro.build.version.incremental command, which will give the exact build number, ignoring any graphical interface bugs.
