How to accurately determine the version and region of the firmware Xiaomi phone

Owners of Xiaomi, Redmi and POCO smartphones often face the need to know the exact version of their device, which may be required when buying a used gadget, finding the right firmware, or when you have problems with banking applications and NFC. The differences between the Chinese, global and European versions can be critical for functionality.

There are a number of ways to determine a modification, from simply visually inspecting the box to using special engineering codes. In this article, we will discuss each method in detail so that you can confidently tell which Xiaomi is in your hands.

Understanding the differences between Global Version and Global ROM is the first step to making good use of the ecosystem, and a mischosen version of the software can result in the absence of important communication frequencies or the inability to install Google services.

Visual check of the box and stickers on the case

The easiest way to know the origin of the device is to look carefully at the package. The back of the box usually has a white sticker with technical information. Look for the Model or Mi Model field. If the model code ends with the letter C (e.g., M2101K7AG), you're looking at China Version. Global versions are often labeled G or I (for India).

Also, look at the certification logos. The global version box must have a CE (European Standard) sign and an Android logo that says "Works with Google." Chinese boxes often don't have these signs, and the characters and MIUI logo are dominant without Google binding.

⚠️ Warning: The sticker on the case of the smartphone can be replaced by the seller. IM-code specified on the box, with what is displayed in the system or on the tray for SIM-map.

If you buy a device from hand, ask the seller to send a photo of the label.The absence of Russian instructions in the kit or the presence of a plug charger of a type that is not standard for your region (for example, flat Chinese) can also indicate CN Version.

Analysis of the model code in the smartphone settings

The most reliable software method is the information in the settings menu. → The phone. At the top of the screen, you'll see the name of the model. However, the line "Version" hides more detailed information. MIUI" or “OS version".

Click the MIUI logo or version name several times in a row to open the extended menu, and here you will see the full build code. The key element is the letters after the version number. For example, on the line 14.0.3.0.TKGMIXM, the last characters indicate the region:

• 🌍 MI — Global (International version, supports all languages and Google).
• 🇪🇺 EU — Europe (European version, often with less pre-installed garbage).
• 🇮🇳 IN — India (Indian version, there may be restrictions on the NFC or pre-installed local annexes).
• 🇨🇳 CN — China (Chinese version, no Google out of the box, lots of Chinese software).
• 🇷🇺 RU — Russian version, now rare, mostly on older models).

It is important to distinguish between Global Version (the device originally released for the world) and Global ROM (the Chinese phone that has been reflashed to global firmware), in the second case, the model code may retain the letter C, although the firmware name will be MI.

Use of the engineering menu and USSD-code

To get hidden technical information, you can use special codes entered in the Phone app, which allows you to quickly check the version without diving deep into the menu. Open the dialer and type ##64663#. This will open the CIT (Customer Information Test) engineering menu.

In the menu that opens, select Version Information or just look at the top line. This shows you detailed information about Hardware and Software. Pay special attention to the Region field. If it says Global, but you bought a phone as Chinese, you probably did a firmware reflash.

##64663##

Another useful code to check the status of locks and region is ##4636##. Going to Phone Information, you can see more detailed network information that can also indirectly point to the region (for example, supported LTE frequencies).

Table of compliance of region codes Xiaomi

So you don't have to guess, we've prepared a summary table of the main codes found in the MIUI version bar, and these two characters are at the end of the version line and are the main indicator.

Note the line with the code CN. Chinese versions often lack support for 20th and 66th LTE frequencies (B20, B66), which are actively used by operators in Europe and Russia for coverage in buildings and outside the city.

💡

Use CellMapper or LTE Discovery to check what Bands your phone is actually using in your current location, which will help you see if your device has enough bands for quality internet.

Differences between Global Version and Global ROM

This is the most confusing moment for beginners. Global Version is a smartphone that is originally designed and assembled for the international market.It has the appropriate labeling on the box, it comes with a global power supply, and the factory has a global firmware with an unlocked bootloader (usually).

The Global ROM (or China-re-imprinted) is a device originally designed for the Chinese market, where the seller or user has self-erased the Chinese system and installed a global one. Visually, the difference may not be noticeable, but there are nuances:

• 🔒 Bootloader: On Global Version, the bootloader is often unlocked or easily unlocked officially. On re-flashed versions of China, the bootloader can be blocked, which will not allow you to return Chinese firmware or install custom software.
• 📉 Updates: Global versions get updates stable. Automatic updates on re-flashed devices (OTA) may not work or lead to a “brick” if the firmware region does not coincide with the region of the device.
• 🏦 Banking applications: On the properly installed Global ROM Google Pay (Wallet) and banking apps work fine, but if you reset the settings to factory settings, the phone can go back to China, and you have to reconfigure everything.

⚠️ When buying a smartphone on marketplaces like AliExpress, if the product name says "Global Version", but the price is suspiciously low - with a probability of 99% is overstuffed China (Global) ROM). The real Global Version costs the same as the official store.

Checking through computer and ADB

For advanced users who want a 100% guarantee, there is a method of checking through the ADB (Android Debug Bridge. This is a way to see the underlying properties of the system that are not hidden by the interface. You'll need a PC, USB-cable and installed drivers ADB.

Connect the phone in debugging mode via USB and enter the following command in the command line:

adb shell getprop ro.boot.hwc

This command will return the hardware region code. It's also useful to check the ro.boot.country property. If the system returns CN and the settings say Global, you're looking at a flashed device. This is the most accurate technical identification method, because these properties are written in the factory and it's hard to change software without the bootloader flashing.

💡

The combination of verification methods (box + code in settings + ADB) gives 100% guarantee of determining the version of the device.
