Owning a modern Xiaomi or Redmi smartphone often requires regular maintenance of the device. Users are faced with the need to install a specific application, fix a software failure or simply understand whether their operating system is relevant. In these situations, the first and most important step is to identify the current software. Without accurate data on the firmware version, it is impossible to correctly select files for recovery or assess the security of the device.
Many gadget owners confuse the version of the Android operating system and the version of the user shell MIUI or the new HyperOS. These are fundamentally different concepts: Android is the basic core, and the shell determines the appearance and functionality of the interface. It is the version of the shell that most often interests users when finding solutions to technical problems. Understanding this difference allows you to quickly find answers in technical documentation and in profile forums.
There are several ways to get comprehensive information about your software. Some methods are available to the average user through the standard settings menu, others require you to go to the engineering sections. The global version of the firmware always has the MIUI Global index, while the Chinese version is labeled as CN. In this article, we will discuss all the diagnostic methods available so that you can get accurate data about your device at any time.
Verification through the standard settings menu
The most obvious and safe way to get information about software is through the standard interface of the system, and to do that, the user needs to unlock the screen and find the Settings app, which usually looks like a gear, and inside the menu, you need to scroll the list to the very top of the About phone block, and clicking on this, you will open the screen with basic technical information.
The section that opens draws attention to the large digit of the MIUI or HyperOS version, such as 14.0.5. However, this figure hides more detailed information. If you tap the version name or the system logo several times in a row, an extended menu will open, and this is where the full alphanumeric firmware code, which is necessary to search for recovery files or verify the regional identity of the device, is displayed.
⚠️ Note: Do not try to change the settings in the extended version menu unless you are sure of your actions.Accessal resetting of settings in this section can lead to data loss or change of regional settings of the device.
The details in this section provide insight into not only the build number, but also the release date of the version, which is critical to assessing the relevance of security patches. If your build date is older than six months, check for updates, and see the current level of the Android security patch, which is important for users who care about protecting personal data.
☑️ Checking the menu
Use of the engineering menu and USSD-code
For deeper diagnostics beyond the standard user interface, there are special codes. Entering the combination ##6484## in the Phone app (Director) automatically redirects the user to the CIT engineering menu. This section is designed to test hardware components, but also contains information about the software part of the device.
Inside the CIT menu, you can find a version of the basic modem and radio part, which is especially true for problems with communication or mobile Internet. Sometimes it happens that after flashing the shell version is updated, and the radio module remains old, which causes unstable network operation.
Another useful code is *#06#, which displays information about IMEI and serial number. Although this code does not directly show the firmware version, IMEI knowledge is necessary to verify the device on the manufacturer's website. By typing IMEI into a special service, you can see which version of the software was installed in the factory and what updates are officially available for this particular instance.
Secret codes for different regions
Extended information in the menu "For developers"
The hidden section for developers provides access to technical information that is usually hidden from the eyes of the average user. To activate this section, you need to quickly click 7-10 times on the About Phone menu on the MIUI version. Once you have become a developer, a new item will appear in the settings menu.
Inside the developer section, you can find detailed information about the build of the Linux kernel on which Android is based, which is important for enthusiasts who plan to install customized Recovery or modified firmware. Core compatibility is often a key factor in successful third-party installations. SDK Android.
If you plan to modify the system in the future, Bootloader's status is crucial, and this section often duplicates information about the current build, but in a more technical format that is convenient for copying and pasting into error reports.
Analysis of system properties through ADB
For advanced users with access to a computer, the most accurate method is to use the Android Debug Bridge (ADB) debugging tool, which allows you to pull system properties directly from the device configuration files. To get started, you need to include USB debugging in the developer menu and connect the smartphone to the PC.
After installing the drivers and setting up the ADB, you should enter a command in the computer's command line to output all system properties.
adb shell getprop | grep ro.buildExecuting this command will give you a long list of parameters. We are interested in lines starting with ro.build.version.incremental. ro.build.version.op_miui (This method is good because it shows raw data that cannot be tampered with or altered through the user interface, and is ideal for checking system integrity after buying a device from hand.
⚠️ Warning: When connecting your smartphone to someone else's computer for debugging, always check for debugging permission. Do not confirm access on unfamiliar devices to avoid data theft.
Decoding of letter designations in the name of the firmware
The full firmware version number is not just a set of numbers, but encoded information about the region, build type and release date. Understanding the structure of this code allows you to instantly determine the origin of the software. Global firmware usually has the word Global in its name, and Chinese firmware usually has the word CN in its name.
It's also important to look at the lettering at the end or middle of the code, for example, if you have a T, you can have a carrier version, and if you have an E, you can look at the European region with the recalibration of the frequencies.
| Designation | Description | Region |
|---|---|---|
| MIUI CN | Chinese stable version | China |
| MIUI Global | Global stable version | Peace. |
| MIUI EU | European version (often custom) | Europe |
| MIUI RU | Russified version | Russia/CIS |
| MIUI IN | India version | India |
Knowing regional identity is critical when trying to change firmware type: switching from Chinese to global requires an unlocked bootloader and complete data cleanup; trying to install firmware from another region on top of a closed system without preparation will lead to errors or a “brick” of the device.
💡
When buying a smartphone in the secondary market, be sure to check the region of the firmware with the box. If the Global box is the CN version, the device could be re-flashed, which affects the operation of notifications and banking applications.
Verification of relevance and search for updates
Once you know the current version, the logical next step is to check its relevance. Manufacturers regularly release updates to close security vulnerabilities and improve stability. In the system update menu, you can not only check for a new version, but also see the update history.
Sometimes automatic updates don’t come because of staged rollouts, so knowing the exact number of the current build helps you manually find and install the current version through Recovery mode, but only for experienced users who understand the risks.
There are specialized applications and web services that tell you by model number and current version if your firmware is the last available, a convenient way to avoid manual checks on the manufacturer's website, and regular software updates are the best protection against viruses and software errors.
💡
Regular verification of the firmware version and timely update to the current build is the key to the stable operation of the smartphone and the security of your data.
