How to find out the firmware Xiaomi: full instructions for all models

Modern smartphones Xiaomi, Redmi and POCO are built on the basis of the Android operating system with the proprietary shell MIUI or the new HyperOS. Periodically, each owner needs to accurately identify the installed version of the software to find solutions to problems, install updates or rollback of the system.

The current build information contains critical data: distribution region, release date and version number, and understanding these parameters avoids errors when manually updating via Recovery or Fastboot.

In this article, we will take a closer look at all the available methods for obtaining technical information about your device’s software, and we will look at both the standard settings menu and the hidden engineering codes that work even in the event of software interface failures.

Verification of the version through system settings

The most obvious and safe way to get system data is to use the device's regular menu, which is a non-computer-connected method that's available to anyone, so you just unlock the screen and find the settings icon.

Depending on the version of the shell (MIUI 12, 13, 14 or HyperOS), the location of the items may vary slightly, but the logic remains the same. You will need to open the About Phone section, which collects the basic technical specification of the gadget.

The screen will display a large digital version marking, such as V14.0.3.0.TKGMIXM. This code defines the region and type of firmware. By clicking on the system logo several times in a row, you can turn on or off the automatic update.

If the standard path seems too complicated or the menu doesn't respond, you can use an alternative way through search, and at the top of the settings menu, there's a search bar where you just type in the word "version" or "about phone."

⚠️ Note: Do not try to reset the settings in this menu if your goal is simply to find out the version of the software. Reset will delete all personal data without the possibility of recovery.

For a deeper analysis, you can use the processor and memory details that are also displayed on this screen, and these data are useful for custom cores or system modifications.

Use of the engineering menu and USSD-code

When the graphical interface is damaged or the phone is stuck on the logo, hidden commands come to the rescue, and they are typed through a standard "bell ringer," like a regular phone number, and this method works at the base system level.

The most universal code for Xiaomi devices is ##6484##. Entering this combination automatically opens the device. CIT-A Cit Test for hardware diagnostics, where you can check the sensor, the speakers and the cameras.

However, the firmware version is more commonly used for the code ##4636##. It opens the testing menu, where the Phone Information section displays detailed information about the Build number and SDK version.

• 📱 Code 1: #6484## Complete testing of equipment (CIT).
• ℹ️ Code 2: #4636## - Technical information about phone and network.
• 📶 Code 3: #726### - Preferred network type settings (for advanced networking).
• 🔍 Code 4: *#06# - Display IMEI and serial number of the device.

Not all codes work on all versions of Android.In Google's latest security updates, some hidden menus may be blocked by the manufacturer.

Decoding the code of the firmware version

Once you have a long set of characters, you often don't know what it means. The version code is not a random set of characters, but a structured string of data. Let's take a look at V14.0.5.0.RGCMIXM.

The first letter or combination of letters indicates the version of Android on which the shell is based. The numbers represent the major and minor versions of MIUI/HyperOS. But the most important segment for the average user is the region.

The third two-letter group defines geographic reference, which determines the availability of ads, pre-installed apps and the frequency of updates, and global versions usually arrive later than Chinese ones, but are more stable outside China.

The last letters often indicate a device or build type (Stable, Beta), which is a structure that avoids installing inappropriate software that can turn a phone into a brick.

Definition of firmware through computer (ADB)

For advanced users who want to get comprehensive technical information, Android Debug Bridge is the perfect tool (ADB). This method requires connecting the smartphone to the PC through USB-cable and availability of installed drivers.

ADB allows you to request data directly from the system without having to go through the GUI, which is especially useful if the phone screen is broken but the system is working, or if the sensor is not responsive to touch.

First, you need to enable debugging over USB in the "Developers" menu, and after connecting to the computer, a request is entered in the command line to get the build version property.

adb shell getprop ro.build.version.incremental

This command will return the exact build number, and you can also ask for device model and region code information from individual teams, which is a professional diagnostic method.

⚠️ Attention: For work ADB Xiaomi drivers are required USB Driver. Without them, the computer won't see the device in debugging mode.

Using console commands gives you a sense of complete control over the device, and you can not only control the version, but also manage processes, install applications and make full backups.

Checking with Mi Account and Cloud

Xiaomi’s tightly integrated ecosystem with cloud services, if your smartphone is tied to Mi Account, device information can be found remotely, which is useful if the phone is lost or physically inaccessible.

When you access the official cloud service website through a browser, you enter your personal account, and the device section displays a model and sometimes a version of the software if the phone has recently logged on.

However, this method does not always display the exact current firmware version in real time; the data can be updated with a delay.

• ☁️ Go to i.mi.com.
• 🔐 Sign up with your Mi Account.
• 📱 Select the section "Find the device».
• ℹ️ Check out the connected gadget card.

This is a good way to quickly check if the server is seeing your device, so if the phone isn't listed, it's been offline for a long time or the account has been untied.

Frequent questions and problems of version definition

Users often experience a situation where the claimed version is not the same as expected, which may occur after customization of the system or installation of modified assemblies, in which case standard menus may show false data.

Some enthusiasts are changing build.prop files to hide real hardware or region, and detecting such manipulations will require the use of specialized software like CPU-Z or AIDA64, which reads data directly from chips.

And you also have to remember that there are test builds, and engineering versions of software can have unstable work and strange numbering, and if you bought a phone with your hands and you see a weird version, be careful.

💡

Install the CPU-Z app from the Play Market to see detailed hardware and software platform information in a user-friendly interface.

Always double-check information from multiple sources if you plan to make major changes to your system. A mistake in determining the type of firmware can cause your smartphone to fail.

💡

Accurate knowledge of the version and the region of the firmware is the key to successful updating and security of your data when working with system files.
