The Chinese giantβs smartphone owners often face a situation where they need to identify a device accurately, such as searching for drivers, firmware, buying accessories or getting a warranty. However, the commercial name that flaunts on the box and the actual technical name in the system are often different, which is confusing, for example, the popular Redmi Note may be hiding a completely different code ID.
Understanding the difference between a marketing name and system code is critical to getting your device right. In this article, weβll look at all the methods available, from simple visual checks to advanced engineering menus, learn how to distinguish between global and Chinese versions, and understand why MIUI sometimes hides the true face of your device.
Knowing the exact modification will save you from installing incompatible software that can turn a device into a brick.We will look at the standard Android operating system tools and MIUI shell, as well as methods for advanced users. Don't ignore these details, as even a slight difference in one letter of code can mean a difference in hardware stuffing.
Search for information in system settings
The most obvious and safe way to get data about the device is to look at the standard settings menu, but the path to the information you need may vary slightly depending on the version of the shell you install. Most of the time, you'll need to go to Settings and then select About, and that's where the basic configuration information is hidden.
Note the "Device Model" box. Often it shows exactly the alphanumeric code you want to find firmware. If you see a name like "Redmi Note 10 Pro" but you want a technical code (like sweet or global), you need to do a few quick taps on the line with the version of MIUI. This action will open an extended menu that will show the code names, the Android version and the build date.
In some cases, especially on Chinese firmware, information can be presented in hieroglyphics or abbreviated form. Then you should pay attention to the build number or code name, which is often duplicated in Latin.
β οΈ Warning: Don't blindly rely on the name displayed in the store's advertising materials.The real model is determined only by internal system identifiers.

If you see Chinese characters in the About Phone menu, try switching the system language to English or Russian so that the lines with the codes become readable.
This section also often indicates the region of the device, which is an important parameter, as CN (China), EU (Europe) and Global versions can all have different frequency bands and pre-installed services. Make sure you look at the model instead of the software version, although they are often correlated.
Use of the engineering menu and USSD-code
To get deeper diagnosis and hidden information, the developers left special character combinations. By typing them into the Phone app, you can activate hidden test modes. One of the most useful codes for Xiaomi devices is ##64663##. This character set triggers the CIT (Customer Integration Test) menu, which is used in factories to check hardware.
In the test menu you can find the exact name of the model, version PCB-boards and other technical details that are not displayed in the normal interface, navigation is carried out through the volume and power buttons or by touching the screen, depending on the specific model. Be careful not to run tests that can reboot the device or change the calibration of sensors without the need to.
- π± *#06# - displays IMEI Serial number, which can also identify the device in the databases.
- π§ ##4636## - Phone, battery and usage statistics testing menu (not available on all versions) MIUI).
- πΆ ##225## - Event calendar information (less useful for the model, but sometimes contains data about the region).
- βοΈ ##6484## - Alternative login to the engineering menu on some older Redmi models.
It is worth noting that on newer versions of Android and MIUI, access to some code may be restricted for security reasons. If the code does not work and nothing happens, then the manufacturer has blocked this feature in this version of the firmware, in which case it is worth trying third-party applications to collect information about the system.
Why can codes not work?
Analysis of information on the body and packaging
Physical inspection of the device and its original box is a classic method that is often overlooked: the back of the smartphone, usually at the bottom, has a marking on it. Depending on the year of release, there may be a sticker or an engraved line. Look for the "Model" line, followed by an alphanumeric code, such as the M2101K6G.
The box from the device contains the most complete information. On one side, there is usually a white label with barcodes. It shows the exact model, color, memory, IMEI, serial number (S/N) and production date. If you buy a used phone, reconciliation of the model on the box and in the system is a mandatory step of checking for originality.
| Designation | Meaning | Example |
|---|---|---|
| Model | Technical code of the model | M2010J19SG |
| S/N | Serial number of the device | 8Y9HB204500XXX |
| IMEI | International identifier | 865432101234567 |
| Input | Charging parameters | 5V-2A / 9V-2A |
Note the suffixes at the end of the model code: The letter G often stands for the global version (Global), the C for China, and the I for India, and these differences are important when looking for parts, as charging connectors or camera modules can vary by region.
If the sticker on the case is worn or missing (which is often the case on refurbished devices), the box remains the only physical source of truth. However, remember that the box can be confused, so always double-check the data by software methods. Keeping the box also makes it easier to return the goods under warranty.
Application of third-party software and ADB
When the built-in tools don't give you the full picture, Google Play apps come to the rescue. Programs like CPU-Z, AIDA64 or Device Info HW read data directly from system files and output them in a convenient way. In the "Device" or "System" section, you'll see the exact codename you need for the firmware.
For advanced users with access to a computer, the ideal tool would be ADB (Android Debug Bridge), which is by connecting the phone in USB debugging mode, you can get comprehensive information through the command line, which works even if the phone screen is broken, but the system boots.
adb shell getprop ro.product.model
adb shell getprop ro.product.deviceThe first command will return the commercial name of the model, and the second will return the code name of the device (for example, lmi for Xiaomi Mi 10 Pro). These data are the most reliable, as they are taken from the system properties of build.prop. No user settings can change these values software without flashing.
βοΈ Check through ADB
Using ADB also allows you to see information about the bootloader and status of the device, which is especially useful when buying used equipment to make sure that the phone is not blacklisted or has a locked bootloader from the enterprise versions.
Decoding of code names and numbering
Xiaomiβs understanding of the logic (naming) helps you determine the characteristics of the device immediately. Code names are often associated with famous characters, plants or phenomena. For example, the Redmi Note series often uses the names of flowers or spices, and the flagship Mi β the names of rivers or cities.
Model numbering also follows a system: the first two digits often indicate the year of development or series, and the subsequent characters indicate a specific modification, and knowing these patterns, you can approximate the date of a device even without access to Internet databases.
It is important to distinguish between global and regional versions at the end of the model number. As mentioned earlier, suffixes play a key role. A device with code intended for the domestic market of China may not support some LTE frequencies used in Europe or the CIS, which will lead to poor signal reception.
β οΈ Note: When you run a global version of the Chinese device (and vice versa) you can lose the opportunity to use NFC-Payment (Mi Pay) or receive a broken Widevine L1 (will not HD Netflix).
There are online databases where you can type in the code you find and get the full specification. However, it is better to remember the logic once so as not to depend on third-party resources. For example, the presence of the letter "S" in the code often indicates the presence of an NFC module in some Redmi series.

A code name (e.g., βdavinciβ) is more important than a commercial name when searching for firmware and modifications on developer forums.
Frequent problems and their solution
Users often experience a situation where the phone is identified as another device, which may occur after unskilled repairs, when the motherboard or plumes have been replaced, in which case the system information may not correspond to the physical case.
Another common problem is rebranding, and some marketplace vendors are refashioning Chinese versions to global ones, changing the IMEI and the model software, and these devices may stop being updated over the air or get blocked by the manufacturer, and checking through ADB or bootloader helps to detect such manipulation.
If the settings display "Unknown" or the model is not correctly defined, the persist or misc partition in memory may be damaged, and recovery of this data requires professional intervention and the presence of a memory dump from an identical, serviceable device.

- π Global firmware (Global) works more stable with our networks than Chinese ones (China).
- πΎ Section backup EFS critical in any manipulation of the device model.
Always double-check information from multiple sources, if the program shows one model and the sticker on the case of another is a red flag, in such cases it is better to refrain from buying or deeply interfering with the system until you find out the reasons for the discrepancies.
