Where is the build number in Xiaomi: search, decryption and value

Owners of Xiaomi, Redmi and POCO smartphones often face the need to know the exact version of the software installed on their device, which may be required when searching for bugs, installing custom recaps, or simply to understand the relevance of your MIUI or new HyperOS. The build number is a unique identifier that tells developers and advanced users about a particular firmware version, its compilation date, and even the release region.

Many users confuse the build number with the Android version or the common version number. MIUI, It's important to understand that the Build Number contains much more technical information encoded in alphanumeric format, and this is the parameter that is often requested in service centers or forums when discussing problems with the system. OTA-update.

In this article, we will look at where exactly this parameter is hidden in the system, how it is correctly interpreted and why it is important for the safety and stability of your gadget. We will look not only at the standard paths in the menu, but also at how to get information through the computer, which is especially important for devices with a broken screen or a damaged system.

Main path: search in the menu "About the phone"

The easiest and most obvious way to find the desired option is in the standard system settings menu. You don't need special rights or a PC connection. Just unlock the screen and go to the Settings app. At the top of the list, usually just below the search bar or account avatar, is the About Phone (or About Device).

When you open this section, you'll see the basic information: the processor model, the Android version, and the MIUI/HyperOS version. However, the default build number itself is hidden from the eyes of the average user to avoid confusion. It's located on the same line as the operating system version. To see the full code, you need to tap the line with the MIUI version several times, but in this context, we just need to look closely at the text under the version title.

⚠️ Note: Do not confuse the line "version" MIUI Android" with a separate "Build Number" field in the extended menu, and in modern shell versions, they can be displayed differently depending on the regional firmware (Global, China, EEA).

Often users search for a separate graph, which may not be on the main screen of the menu “About the phone”, in this case, you should pay attention to the field version of MIUI. It is under it or next to it in small print is the same code starting with, for example, V14.0.5.0 or OS1.0.2.0. This is a brief entry of the build number, the full version of which will be revealed on detailed examination.

⚠️ Note: On some devices with Chinese firmware (CN ROM) You can look for characters that correspond to the word "version," or use a screen translator if you don't speak the language.

How to see the full version code through taps

To access the full technical identifier required to flash through the Mi Flash Tool, there is a hidden mechanism. In the About Phone menu, find the line where the version is specified. MIUI (for example, MIUI 14 or hyperos 1.0). You need to quickly click on the logo or text of the version 7-10 successively.

After a series of taps, the system will pop up a pop-up notification at the bottom of the screen: "You're a developer!". This action activates the hidden menu for developers, but also often changes the display of version information. Once the developer mode is activated, go back to the About Phone menu and look at the version bar again. Now it can display the full Build Number, which looks like a long string of characters, for example: V14.0.7.0.TKGMIXM.

If after activating the developer mode, the full code did not appear immediately, check the menu that appears Advanced Settings. → For developers, there may be a "My Version" or similar item that contains the full information, and the full code is always displayed when you boot the device, right after the logo. MI Xiaomi, if you look at the bottom right corner of the screen.

Decoding the structure of the assembly number

Understanding the structure of the build number helps you instantly determine which version you have: global, Chinese or European. The code consists of several segments, each of which carries a meaningful load. V14.0.5.0.TKGMIXM.

The first part (V14.0.5.0) indicates the shell version. The number 14 is the major version of MIUI. The following numbers indicate minor updates and security patches. The second part of the code (TKGMIXM) is the most important for identifying the region. The letters in the middle of the code indicate the device code name and region.

💡

The last two or three letters in the assembly code indicate the region: MI – Global, EU – Europe, CN – China, RU – Russia, IN – India.

Let’s consider the table for a visual comparison of regions in the assemblies numbers:

Knowing these designations, you will never confuse Chinese firmware with global firmware, which is critical when trying to unlock the bootloader or restore the device after a failure, since firmware in an incompatible region can turn a smartphone into a “brick” or cause communication problems.

Search for build numbers via ADB and Fastboot

If the smartphone screen is broken, the touchscreen is not working, or the device is getting stuck in a bootloom, the standard path through the settings is not available. ADB (Android Debug Bridge.This method requires that the phone previously turned on “Debugging by” USB».

Connect your smartphone to your computer, open the command line in the ADB tool folder and type in the command:

adb shell getprop ro.build.version.incremental

This command will display the exact number of the current build. If the device is in Fastboot mode (loading with a picture of a rabbit repairing an android), the information is displayed directly on the smartphone screen.

fastboot getvar all

In the answer, among the many lines, find the bootloader version-base or similar field that will contain the code you want, which is the most reliable way to know the version when the system is not fully booted.

The value of the build number for OTA updates

The build number plays a key role in the air-to-air update engine (OTA). Xiaomi servers compare the build number installed on your device to the build numbers available for download. If your version is newer or equal to the current one on the server for your region, the update will not come.

Often users are faced with a situation where the global version came Chinese build or vice versa, this is due to errors in determining the region or changing the region in the settings, the system may suggest upgrading to a version that is technically newer on the compilation date, but is intended for a different market.

⚠️ Warning: Forced installation of another region build via the update menu (file selection) can result in data loss or device lock.Always check the last letters of the code before installing.

There are also “stable” and “beta» (Beta/Developer) The beta number often has a prefix. DEV Installing a beta build over a stable one usually requires complete data cleaning (Wipe Data), which the system will warn you about.

💡

Before installing a new build, make a full backup of data through the Mi Cloud or on your computer. Even a regular update can be error-prone, and the possibility of rollback will be a salvation.

Problems with definition of the version and their solution

Sometimes users encounter interface bugs when the build number is not displayed correctly, such as “0.0.0.0” or simply does not change after an update, which may be due to corrupt system files or a failed cross-regional update.

In such cases, it is recommended to reset the settings to factory. Before you do, make sure you remember the data from your Google account and Mi Account. If the problem persists even after the reset, it is possible that the phone memory contains files from the old firmware that conflict with the new one.

Also worth checking the integrity of system files through Recovery mode. Press the Volume Up button and Power when the phone is off. The Recovery menu (Chinese or English) can also display the current version of the firmware, which will allow you to diagnose the problem even without booting the OS.
