Owning a device from the Chinese giant often poses a mystery to users about what your gadget is called. Unlike other brands, the Mi ecosystem uses a complex naming system, where the marketing name (such as the Redmi Note 10 Pro) often differs from the technical identifier (M2101K6G), a distinction that becomes critical when looking for firmware, buying parts or issuing warranties.
Knowing the exact technical article helps avoid errors in system recovery. Many beginners confuse global versions with Chinese ones, which leads to incompatible software installation. To avoid turning a smartphone into a brick, you need to clearly understand what kind of hardware you are holding.
There are several proven methods of device identification, from simple visual to advanced software, and we will look at each of them so that you can get full information about your device in minutes, regardless of the state of the operating system.
Identification through MIUI and HyperOS system settings
The most obvious and accessible way is to look at the menu of the smartphone itself. The MIUI or the new HyperOS interface hides all the technical information in the About Phone section. However, by default, the system often displays only a beautiful marketing name, hiding the real code of the model.
To reveal hidden data, you need to perform a specific action: Find a line with the model name (for example, Xiaomi 13) and quickly click on it 5-7 times. The screen will change, and instead of the commercial name, a technical code starting with the letter M (for example, 23013PC75G) will appear.
Here you will find information about the version of the operating system, the processor and the amount of RAM, which is necessary to verify the authenticity of the device and compatibility with regional firmware. Note the end of the code: the letters at the end often indicate the region (G - Global, C - China, I - India).
💡
The marketing name and the technical code of the model are different identifiers. Always use the technical code that is hidden by default to find firmware and parts.
If the standard path is not working or the menu is blocked, you can search by settings, type the word "model" or "version" in the search bar, and the system will redirect you to the desired section, which is especially convenient on large screens, where it is difficult to manually search for the desired item in long lists.
Use of the USSD-codes and engineering menus
When access to the settings menu is limited or more technical information is needed, secret combinations come to the rescue, and entering special codes into the Phone app opens up access to hidden parts of the system, known as the CIT (Customer Integration Test).
For Xiaomi devices, the most versatile code is ##6484##. Once the last character is entered, the screen will automatically switch to the test menu, and you can not only see the model, but also check the performance of all sensors, screens and communication modules.
- 📱 Version. MIUI: It shows the exact assembly of the software.
- 📡 IMEI/SN: Unique Equipment Identifiers.
- 🔋 Battery: Real Capacity and Charging Cycles.
- 📶 Network: Status of Communication Modules and antennas.
Another useful code is *#06#. It instantly displays it on the screen. IMEI-All SIM card codes and the serial number of the device are critical when locking a stolen phone or checking the device against a database before buying from hand.
What do I do if the codes don't work?
It's important to understand that the engineering menu is for diagnostics. Changing the settings in the sections you're not sure about can cause the radio module to malfunction or recalibrate the screen. Use this tool only to view information if you're not an experienced user.
Analysis of factory packaging and documentation
If the smartphone doesn't turn on, the most reliable source of information is the original box, which requires manufacturers to put on the packaging all the key data that duplicates information from the system, which is the only way to know the model of the "dead" device without running it.
Look for a barcode sticker, usually located on one of the side faces or at the bottom of the box, that contains the Model (model), IMEI, serial number (SN) and current input, and that is the model code listed here, which is the ultimate truth for service centers.
| Label field | Description | Example of meaning |
|---|---|---|
| Model | Technical code of the device | 21061110AG |
| IMEI 1 | Identifier of the first SIM | 866453041234567 |
| S/N | Serial number of the party | 9340218/3001234 |
| Input | Charging parameters | 5V-3A / 9V-2A |
Pay attention to the integrity of the sticker. If it's overstuffed, has autopsy marks, or the data on it doesn't match the ones that are displayed when you turn on (if the phone is working), this is a sure sign of device recovery or case replacement.
You can also find information on the warranty card or instructions, if they are preserved, which often spells out the full name of the model and the region of sale, which helps distinguish "European" from "Chinese", which is critical for the job. NFC-modules and frequency ranges 4G/5G.
Checking through a computer and ADB-team
For advanced users with access to a PC, there is a way to get the most detailed information through USB debugging, which works even if the phone screen is broken, but the touchscreen partially reacts, or if the system does not load to the end.
You will need to install Xiaomi USB Drivers and SDK Platform-Tools. Once you connect the device in debugging mode (USB Debugging), you can use the command line to request data directly from the Android system.
adb shell getprop ro.product.model
adb shell getprop ro.build.version.incrementalThe first command will output the exact model code, and the second will output the build number, and the good thing about this method is that it reads data directly from build.prop, which is virtually impossible to modify software without deep intervention in the system partition.
💡
If ADB If you don't see the device, try to press the volume button when you connect the cable. The phone goes to Fastboot mode, and the command `fastboot getvar all` Provide comprehensive information about iron.
There are also graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools. They automatically collect all the information about the device, including the bootloader's unlock status and binding to the Mi Account. It's a great tool for checking the phone before buying from hand.
Model definition by appearance and marking
Visual identification can be difficult because of the similarity of designs across generations, but there are details that give off the model, such as the location of the cameras, the shape of the module and the presence of certain connectors help narrow the search.
Look in the tray for SIM-on many Redmi models and POCO The inside of the tray is laser-engraved with the model code, and to see it, you have to take out the tray and look carefully at it in good light, perhaps with a magnifying glass.
- 🔍 Tray SIM: often contains the model code, for example, M2004J19C).
- 📷 Camera module: unique lens geometry for each series.
- 🔌 Connectors: presence or absence of a 3.5mm minijack.
- 🧩 Logo: Logo location Xiaomi/Redmi back-panel.
Also worth paying attention to the inscription on the back cover (if it is not glass) or at the bottom of the case. regulatory markings often contain certification codes that can break through the device in the databases of the FCC or EAC.
⚠️ Attention: Don't rely on the look alone. Chinese craftsmen often change the back covers and the case. SIM One thing says, and the settings are different - you need to trust the tray or IMEI, The body could be replaced in the service.
Comparison of technical specifications for accurate identification
If none of the previous methods gave a definitive answer, it remains to compare the hardware. The characteristics of the processor, the screen matrix and the main camera are unique fingerprints for each model.
Use benchmark apps like AIDA64 or CPU-Z. They will show the exact CPU codename (like sm8250 for the Snapdragon 865) and the resolution of the camera sensor, and by matching this data with the spec sheet on the official website, you will pinpoint the model.
Global versions often have reduced frequency bands compared to Chinese ones. If your phone doesn’t catch 4G in a certain range (Band 20), chances are you have a Chinese version, even if the menu says “Global”.
☑️ Checking before buying a b/w
In conclusion, knowing exactly what your Xiaomi model is is the foundation for its long and stable operation: Don’t be lazy to check codes, especially when buying a used device or before flashing it, and it will save you time, money and nerves in the future.
