Users of the Xiaomi ecosystem often face the need to specify the exact modification of their device, which may be required when searching for specific drivers, buying cases or trying to update the operating system manually. However, just knowing a model, such as the Redmi Note 12, is not enough, since the same device can be released for different markets with fundamentally different software shells.
There are several levels of identification, from the base model number to deep analysis of firmware code. In this article, we will break down all the nuances that will help you understand what is in your hands. The global version and the Chinese ROM are two big differences, and you should not confuse them.
The differences are not just in the interface language, but also in the availability of Google services, frequency bands, and even physical features of the case, sometimes in the small things that affect the stability of the gadget in your region.
Visual inspection of the hull and markings
The first and easiest way to get the primary information is to physically inspect the device, and manufacturers often place the key data on the back or in the tray for the device to be used. SIM-Note the lower part of the case, where the small print is printed with technical information.
You can find a model number that consists of letters and numbers here, for example, the M2101K6G marking indicates a specific modification, and it is also worth checking the SIM card tray: on some models, such as the Xiaomi 13 or Poco F5, the version code is stamped directly on the metal frame of the tray.
It's important to check the box against the box. If you're buying a device from hand or in an unofficial store, the discrepancy may indicate a repackaged item or replacement of components. The original package always contains a sticker with an IMEI and a model that should match reality.
- 📱 Look for the model code on the back cover or under the removable battery (in older models).
- 🔍 Check the engraving on the tray for SIM-mapping.
- 📦 Compare the sticker on the box with the data that is stamped on the device itself.
⚠️ Note: If the box has one region (e.g. Global) and the case or system has a Chinese version (CN), This may indicate that the device is flashed by the seller in violation of standard procedures.
Don't ignore the physical buttons. Chinese versions of smartphones often lack physical support for some frequency bands, which is only visible from the specs, but sometimes the antenna markings on the case are different, too. Visual control is just the first filter.
Verification through MIUI and HyperOS system settings
The most reliable software method is to use the built-in settings menu. The MIUI or the new HyperOS interface contains all the necessary information about the software. To access this data, you need to go to the About Phone section.
This shows the Android version, the MIUI version and, most importantly, the firmware type. In the line with the software version, you can often see letter marks at the end, for example, MIUI 14.0.5.0.TKRMIXM. The last two or three letters indicate the region: MI - India, EU - Europe, GL or Global - global version, CN - China.
To see the full information, including the model code, you need to quickly click on the MIUI logo or the name of the firmware version several times. An extended menu will open, where the exact code will be indicated, for example 2201116SG. The letter at the end of the model code is also important: G stands for Global, C - China, I - India.
Note the Advanced Settings or Region section, if the device is originally Chinese but flashed on global firmware, the region settings may not have some countries or strange restrictions, a sure sign of modified software.
- 📲 Go to Settings. → About the phone to view basic information.
- 🔢 Click on the version several times MIUI, Open a hidden menu with the model code.
- 🌍 Decipher the firmware suffix: MIXM (Global), EUXM (Europe), CNXM (China).
⚠️ On cross-stitched from Chinese to global version of smartphones (the so-called Global) ROM base CN) The menu may display incorrect information about the region, although the device will remain functionally Chinese.
Use of the engineering menu and USSD-code
For a deeper diagnosis, you can use the engineering menu, which is a hidden part of the system that is designed to test equipment, and you can log in through a set of special combinations in the Phone application.
The most universal code for Xiaomi and Redmi devices is ##6484##. Once you enter this code, the CIT menu automatically opens. Here you can check the operation of all modules, but we are primarily interested in authentication and component version. In some cases, the build version is displayed in the upper corner of the CIT screen.
##6484##
Another useful code is ##4636##. It opens the testing menu, where IMEI and network type can be seen in the Phone Information section, and although there is less direct information about the firmware version, this method helps identify gray devices that may have changed identities.
What if the code doesn't work?
Some carriers are blocking the entry USSD-If you want to use the code or redirect it to your services, then try dialing the code in the Phone app without pressing the call button. If the menu doesn't appear, maybe your version of the menu is not available. MIUI There are other codes that restrict access to the engineering menu for security reasons *#06# check out IMEI. Bridging. IMEI-The code on the screen, on the box and under the battery (if it is removable) is a must-do when buying, and the coincidence of all three numbers ensures that the device was not assembled from different parts. Understanding the naming logic of Xiaomi models allows you to instantly determine the origin of the smartphone. 10-11 Let's look at the structure of the symbols. 2201116SG. First two digits (22) year of the start of development or release (2022 year). The next digits are the serial number of the model this year. But we're more interested in the last letter. In this case, S stands for Global (international), C stands for China (China), I stands for India (India), R stands for Russia, T stands for Taiwan. The last letter is Region of Features C China (CN) No Google Play out of the box, there's Mi Pay (NFC), Chinese frequencies. G or S is Global (Global) There's Google Play, all languages support, optimization for the world. I India (IN) Is similar to global, but may have specific presets. R Russia (RU) There may be a different set of features from the global cameras, for example, and the global ones that are not important for example, and the Pros, for example, the number 10. Chinese versions (CN) often have faster charging bundled but lack some LTE bands (e.g. Band 20), which is critical for 4G running in rural Europe and Russia. Global Version's differences from Global ROM One of the most confusing points for buyers is the difference between Global Version and Global ROM. This is not the same, and confusion here can cost money and nerves. Global Version is a device originally manufactured by the factory for the international market. It has the appropriate labeling on the box, support for all the required frequencies, NFC for the official method of blocking it, and the most important for the global boarding, the main thing is the global unblocking it is the main method of the original. Global ROM (often CN A Global is a Chinese device that the seller or user has installed the global firmware on their own, often requiring unlocking the bootloader, which is becoming increasingly difficult on new models due to Xiaomi's limitations. Such phones can have a re-stitched bootloader, which blocks the work of banking applications (Google Pay, Mir Pay) and Widevine. L1 (no HD quality in Netflix). 🛡️ Global Version: Official Warranty, Automatic OTA-updates, stable operation NFC. ⚙️ Global ROM: Risk of getting a “brick” when upgrading, possible notification and autoboot issues. 💰 Price: Global Version is always more expensive, as it includes taxes and royalties. ⚠️ Note: On devices with re-flashed Global ROM It is often impossible to pass a security check in banking applications. Before buying, be sure to check whether the phone will reflash. 💡To see if the phone will flash over, try resetting it to factory settings. If the device boots up in Chinese after the reset and requires a complicated activation procedure, this is Global. ROM Chinese version specific versions for different markets (EEA, RU, IN) Beyond the China and Global divide, there are regional variations within the global pool. EEA (European Economic Area: The European version, which is strictly in line with the EU radiation standards. SAR And these smartphones have a forced sound on the camera, which is not software-based in most regions. RU (Russia is almost identical to the global one, but may contain a pre-installed set of Russian software (Yandex, VK, Mail.ru, etc.) in accordance with the requirements of local legislation. Sometimes RU-Versions have changed the logic of the work NFC to support local payment systems if they don't run on standard Google Pay (IN) They are often equipped with chargers with a British type fork (three pins) or have specific logos on the case (for example, Redmi with the logo of the Indian Kriketa). 5G, relevant to other markets. 💡Buying a version EEA or RU ensures full compliance with local frequencies and legislation, while Chinese versions may not work in the country. 4G Frequent questions and identification issues Users often encounter conflicting information in the process of version determination, such as settings that might say Global and model code starting with C. This is a clear sign of flashing. There are also cases where the phone is defined in the PC as the Chinese version, although the menu is all in Russian. It is important to understand that with the release of HyperOS, the company's policy has become more stringent. If you bought a Chinese phone and you try to unlock it with a global account, the system may give you an error. IMEI You can enter a number to see which market the device was originally built for, which is the most reliable way, regardless of what you have "wired" on the phone in the store. Why is my Xiaomi notified from some apps? This is a common problem with Chinese versions (CN) and re-filmed by Global ROM. Aggressive energy saving system MIUI kill off background processes. You need to manually allow auto-start and background work for each important application in the battery settings. How do you know the exact version of Android? Go to Settings → The phone. It will show the version of Android (e.g., the Android version, 12, 13, 14). Remember that the version number MIUI/HyperOS And the Android number is different. MIUI The Chinese versions often run faster out of the box because they have fewer Google background services, but the global versions are more stable with geolocation and notifications in our latitudes. The speed difference on today's processors is almost imperceptible. Can we upgrade the Chinese version to a global version through a global one? OTA? No. Official airborne update» (OTA) available only for the regional version for which the device is intended. The Chinese phone will only receive Chinese updates, and a complete flashing is required to change the region.
