How to determine the firmware version on the Xiaomi phone: a step-by-step guide

Why it is important to know the firmware version on Xiaomi

Every Xiaomi smartphone owner will have to find out the current firmware version sooner or later, which may be needed to install updates, solve application compatibility issues, or unlock the bootloader. The firmware version includes two key components: the MIUI build number (the Xiaomi branded shell) and the Android version (the base operating system).

Without accurate firmware information, you risk installing incompatible software, which can lead to a device blink or data loss. For example, trying to flash the Redmi Note 10 Pro with a Poco X3 Pro file even with the same processor will end in error, and to participate in beta testing of new versions of MIUI requires confirming the relevance of the current firmware.

In this article, we will look at all the available methods, from standard settings to hidden engineering menus, you will learn not only how to view the version, but also how to correctly interpret symbols like MIUI 14.0.5.0.SKUCNXM or Android 13 TKQ1.221114.001.

Method 1: Through the basic settings of the phone

The easiest and safest method is to use a standard settings menu, which works on all Xiaomi, Redmi and Poco models regardless of the MIUI version.

1. Open the Settings app (the gear icon on the home screen).
2. Scroll down and select the About Phone section.
3. Slip on the first line of the MIUI version - here will display the full information.

On this menu you will see:

• 📱 Version. MIUI — for example, 14.0.5.0 (where 14 is the shell version number, 0.5.0 is the assembly).
• 🤖 Android version – for example, 13 TKQ1.221114.001 (13 - OS version, the rest - security patch).
• 🔧 Model number - for example, 22101320C (For the Redmi Note 12 Pro+).
• 🏷️ Region Code - letters at the end of the version MIUI (for example, CN — China, RU — Russia).

Note the region’s code, which is critical when choosing custom firmware, for example, firmware labeled EEA (Europe) may not support Russian, and IN (India) may have restrictions on Google services.

Method 2: Use the engineering menu (#4636##)

The hidden engineering menu provides advanced information about the system, including firmware details, which works on most Xiaomi devices, but can be blocked on some Chinese firmware models.

To open the menu:

1. Open the Phone app.
2. Enter the combination: ##4636## (no spaces).
3. In the window that appears, select Phone Information.

Here you will find:

• 📊 Baseband version (modem version.
• 🖥️ Kernel version (for example, Kernel version, 4.19.157-perf+.
• 📁 Build number – the full firmware identifier, for example SKQ1.211006.001.
• 🔒 Bootloader state: Locked or Unlocked.

💡

If the ##4636## combination doesn’t work, try #284##, which is an alternative code for some Xiaomi models.

In the baseband version, note the first digits, which are the modem version. For example, MOLY.LR12A.R3.MP.V19.5 indicates firmware for the MediaTek Helio G96, which is useful when looking for custom radio modules.

Method 3: Through the System Update application

The update menu not only allows you to install new versions of MIUI, but also displays current information about the firmware, which is convenient because you can check for updates right here.

Instructions:

1. Launch the System Update app (an icon with an arrow in a circle).
2. At the top of the screen will be the current version.
3. Put the badge on. ⚙️ (settings) in upper right corner.
4. Select Package Update → Select Service Package.

This section shows:

• 📦 Current version MIUI — for example, V14.0.5.0.SKUCNXM.
• 📅 Build Date – When your version was released (e.g. 20230615).
• 🔄 Type of firmware: Stable (stable) or Developer (developer).

Ensure that the battery is fully charged (at least 50%)

Connect to a stable Wi-Fi network

Backup of important data

Close all background applications

-->

If you see the following message in the update menu: Your version is relevant, but you know about the existence of a newer build, try manually downloading the firmware from the official Xiaomi website and selecting it through the Select Service Pack.

Method 4: Use ADB-Teams (for experienced users)

If your Xiaomi doesn’t turn on or is stuck on the logo but connects to your computer, you can find out the firmware version through ADB (Android Debug Bridge), a method that requires pre-configuring the debugging over USB.

Step-by-step:

1. Install Platform Tools on your computer.
2. Connect your phone to your PC and enable USB Debugging in Settings → About Phone → MIUI version (tap 7 times to activate developer mode).
3. Open the command line in the adb.exe folder and type:

adb shell getprop ro.miui.ui.version.name


adb shell getprop ro.build.version.incremental




adb shell getprop ro.build.version.release

Transcript of commands:

• 📌 ro.miui.ui.version.name version MIUI (for example, V14.0.5.0.SKUCNXM).
• 📌 ro.build.version.incremental – build number (e.g., build.version, SKQ1.211006.001).
• 📌 ro.build.version.release – Android version (e.g. 13).

If the phone is not turned on but is detected by the computer in Fastboot mode, use the command:

fastboot getvar all

In the conclusion, find the lines version-bootloader and version-baseband - they contain information about the firmware of the bootloader and modem.

Method 5: Special Applications for System Analysis

If you want the most detailed information about your firmware, including kernel, drivers, and modules, use third-party applications that collect data from all system files and present them in a convenient way.

Top.-3 apps:

• 📊 CPU-Z — Android version, MIUI, processor model and kernel assembly date.
• 🔍 AIDA64 — It provides detailed information about the firmware, including the bootloader version and the list of installed modules.
• 🛠️ DevCheck is a user-friendly interface that divides data into categories (OS, hardware, network.

Example of data from CPU-Z for Xiaomi 12T Pro:

Note the field Build Date – if it is older than 6 months, your firmware is outdated and may contain security vulnerabilities, in which case it is recommended to update through Settings → System Update.

Decoding of designations in the version of MIUI

The firmware version of Xiaomi looks like a set of numbers and letters, for example: MIUI 14.0.5.0.SKUCNXM. Let’s analyze what each part means:

The format of MIUI: X.Y.Z.W.DEVICECODE is:

• X is the main version of MIUI (e.g. 14 for MIUI 14).
• Y is the build type: 0 is the stable version. 1-9 is the beta or development version.
• Z.W is the build number (e.g. 5.0).
• DEVICECODE: The first letters are the model (e.g. SKU for Redmi K50 Ultra). The last letters are the region (CN for China, RU for Russia, EEA for Europe).

Examples of decryption:

• 📱 V14.0.4.0.SLRCNXM: MIUI Stable Assembly (0) Assembly number 4.0. Model: Redmi K40S (SLR). Region: China (CN).
• 📱 V13.2.5.0.SKUEUXM: MIUI 13 (second digit 2 is beta). Model: Redmi K50 Ultra (SKU). Region: Europe (EU).

💡

If the MIUI version ends with the letters IN (India) or ID (Indonesia), the device may not support NFC or 5G in some regions.

Knowledge of the region’s code is critical when choosing custom firmware, for example, firmware marked CN will not have Google services, and RU may contain pre-installed Russian applications.

Frequent Mistakes and How to Avoid Them

When checking firmware, users often encounter typical problems, and here are the most common ones and how to solve them:

⚠️ Warning: If the phone stopped turning on after the upgrade, don't try to flash it through Fastboot without backing up.First try Recovery Mode (press Power). + Volume Up) and perform the reset.

Top.-5 mistake:

1. Symptoms: After updating, the Russian language disappears or mobile networks stop working. Solution: download the firmware with the correct regional code (for example, RU instead of CN) from the official MIUI Downloads website.
2. Blocked bootloader: Symptoms: When trying to flash custom software, an Anti-rollback check error emerges. Solution: unlock the bootloader through the official Xiaomi tool (requires a Mi Account and wait 7-30 days).
3. Not enough room to update: Symptoms: Not enough storage error when installing OTA. Solution: clear the cache in Settings → Storage or transfer files to a memory card.
4. Interrupted Update: Symptoms: The phone is stuck on the MIUI logo after the reboot. Solution: wait 10-15 minutes. If it doesn't work, reset via Recovery.
5. Wrong firmware model: Symptoms: This package is for "tissot", this is "santoni". Solution: check the exact model of the device in Settings → About phone → Model and download the firmware for it.

If you see a Can't verify update error when you try to install firmware manually, chances are the file is corrupted. Download it again and check the MD5 checksum (you can find it on the firmware download page).
