How to change the IMEI of Xiaomi phone: methods and risks

Changing a unique mobile device ID is a complex technical procedure that is most often required when replacing a motherboard or recovering lost data. Owners of Xiaomi and Redmi smartphones may encounter a situation where the device’s hardware number is damaged or not read by the system. Understanding how to change the IMEI of a Xiaomi phone is necessary for service center specialists and advanced users engaged in repairs.

However, it is worth noting that interference with the basic settings of the radio module carries serious risks. Mistakes can lead to complete inoperability of the communication module or even “bricking” the device. In this article, we will discuss in detail the technical aspects, the necessary tools and the software that is used for such manipulations.

It's important to understand that IMEI is not just a set of numbers, but a critical parameter for registering with an operator's network. Without the correct value, a smartphone will not be able to make calls or surf the Internet via a mobile network. Next, we'll look at where this procedure is really required and what are the legal ways to implement it.

What is IMEI and why should I change it?

International Mobile Equipment Identity is a 15-digit code that is assigned to every mobile device in the factory, stored in a special nonvolatile memory and serves to uniquely recognize the gadget in the networks of cellular operators, and when this sector of memory is damaged, the phone turns into a media player, unable to communicate.

The main reason why users are looking for information about the change IMEI, If you installed a new board from another device, its identifiers will differ from those shown on the box or under the battery. IMEI It is necessary to work correctly all functions of the phone and avoid network problems.

⚠️ Attention: Change IMEI The purpose of concealing a stolen device or bypassing a locking-in is illegal in many countries.

In addition to replacing the board, the procedure may be necessary after unsuccessful firmware experiments, when the NVRAM partition (where calibration data is stored) was damaged or erased. In such cases, the system may show zero values or give an error "Invalid IMEI". Without restoring this data, the use of the phone for its intended purpose is impossible.

It’s worth noting that modern Xiaomi smartphones have dual protection and complex verification mechanisms. Simply writing numbers through an engineering menu often doesn’t work because of the limitations of the bootloader and partition signatures.

Tools and training required

Before you start any manipulation of system partitions, you need to carefully prepare the workspace and software. Chaotic actions without understanding the processes can lead to irreversible consequences. You will need a computer with a Windows operating system, since most specialized utilities do not support macOS or Linux.

The key element is quality USB-Cheap charging cables often don’t provide a stable connection for data transfer, which can interrupt the writing process to critical memory areas. HS-USB QDLoader 9008 or MediaTek VCOM, depending on the processor of your device.

You'll need specialized tools to work with, and most commonly, you'll need tools like Maui Meta, SN Write Tool, or QCN Writer, and the software you choose depends on the platform, Snapdragon or MediaTek, and the wrong program may not see your phone or write data in the wrong format.

Remember to back up all your important data. The process of flashing or writing to NVRAM often requires a complete cleanup of your device. Save your contacts, photos and documents to the cloud or external storage so you don't lose them forever.

IMEI Change Methods on Different Platforms

The procedure for changing the identifier varies dramatically depending on the processor installed. Xiaomi smartphones use chips from Qualcomm and MediaTek, and each requires a unique approach. There is no universal method that works on all devices the same.

For MediaTek-based devices, the process usually looks more standardized. Once you have superuser rights (Root) and enable USB debugging, you can use an engineering menu or special utilities. The command to log into the engineering menu often looks like ##3646633##, but on newer versions of MIUI, this access may be closed.

Devices on Qualcomm Snapdragon require work with EFS or QCN files. These files contain not only IMEI, but also antenna calibration data. Damage to these files can cause the phone to lose signal even with the correct IMEI. This often requires an unlocked bootloader and EDL mode.

There is also a software method through Root rights and the Chamelephon or Xiaomi IMEI Repair app, which is less reliable and doesn’t work on all models, and involves direct editing of system files, which is extremely difficult on modern versions of Android (10, 11, 12 and above) due to the enhanced protection of partitions.

If you are not sure about the type of your processor, you can find out in the Settings → About Phone → All specs or using applications like CPU-Z. Accurate knowledge of the platform is the key to successfully executing the procedure without fatal errors.

Step-by-step instructions for MediaTek

Consider the action algorithm for MediaTek-based devices, as it is the most common for low-end models of Redmi and Poco. The first step is to activate the engineer mode. To do this, type the dialer code ##3646633#. If the menu does not open, you will need to install a special activator application.

In the menu that opens, go to the Connectivity tab, then select CDS Information and Radio Information. You'll see input fields here. IMEI. For SIM 1 is usually IMEI(1), for the second card — IMEI(2) Enter the command AT+EGMR=1.7, YOUR_IMEI" Note the syntax: quotation marks and commas are required.

⚠️ Note: Enter only your real numbers IMEI, The use of random numbers can lead to the locking of the device by the operator.

After you enter the command, press the Send AT button. The phone can restart or simply confirm the execution by the OK command. For the second slot, the AT+EGMR=1.10 command, "YES IMEI." After you have completed all the actions, be sure to restart the device to apply the changes.

💡

If the AT command fails, try switching the preferred network type in the same menu to "LTE Only", write it, and then return it back, which helps bypass some software locks.

You can check the result by typing *#06#. If the numbers match the numbers entered, the procedure was successful. If the fields are empty or zeros are displayed, then the recording did not occur, and you need to try again with Root rights or via a PC.

Working with Qualcomm and QCN files

For flagship models Xiaomi on Snapdragon processors method AT-It's not working. It's using binary file recording technology. QCN. This file contains a complete map of the radio part of the device. QCN for your particular model in the open access is almost impossible, so often use a backup from the same serviceable machine.

The process begins with EDL (Emergency Download Mode) mode, which can be done by a combination of buttons when the phone is turned off or by using the ADB command: adb reboot edl. In this mode, the device is defined by the computer as a Qualcomm HS-USB QDLoader 9008.

Using the QPST or QFIL utility, you need to download a QCN file to your phone's memory. Importantly, before writing a new file, you often need to delete the old one to avoid conflicts. Once the recording process is complete, the phone needs to be restarted.

The challenge is that on many modern devices, the EFS partition is protected from writing, and you can get around this only with an unlocked bootloader and Root rights, or using paid boxes for repairs, and it's extremely dangerous to climb into this section without proper qualifications.

💡

Working with Qualcomm requires the original QCN file or EFS backup. Trying to write a file from another model is guaranteed to result in signal loss and modem inoperability.

Possible mistakes and ways to solve them

In the process of shifting IMEI And the most common is "Invalid Command," or the lack of response to the problem. AT-This could mean you don't have Root rights, or the engineering menu is blocked by the manufacturer, and in such cases, only flashing through the Fastboot will help.

Another common problem is that the IMEI changes, but immediately after the reboot it returns to its old value or resets to zero, which suggests that the NVRAM file is damaged physically or software protected from writing, and the solution may require a complete re-markup of the memory partitions, which is a complex engineering task.

• 📱 The “Null” mistake IMEI» — Reconstitution of the section is required EFS/NVRAM backup.
• 📡 No network after a shift – incorrect calibration data or incompatible QCN file.
• 🔒 Bootloader Unlock Request – You must officially unlock the bootloader through the Mi Unlock website.

If the phone is no longer defined by the computer or hangs on the logo, you may have damaged the bootloader, in which case only Fastboot mode and flashing the stock version of MIUI will help. Always have the latest firmware for your model at hand.

In some cases, network resets help. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will not delete your personal data, but will return network settings to factory values, which can eliminate software conflicts.

Legal and security aspects

It is important to be aware of the legal side of the matter. In many countries, including the Russian Federation, changing the IMEI to mask a wanted device is a criminal offence, and legitimate reasons, such as repairs, must be documented, especially if you are doing it professionally.

Communications operators have databases IMEI, And abruptly changing the identifier on a device that previously glowed on a network with a different number may cause suspicions in the operator's security system. SIM-maps before the circumstances are determined.

⚠️ Note: Use of software "generators» IMEI It's dangerous to randomly select numbers, and you can accidentally assign your phone to someone else's number, which will cause problems for both subscribers.

The security of your data is also compromised when using third-party software to change IMEI. Many "cracked" versions of programs contain viruses or Trojans that can steal passwords and access banking applications.

Remember that modern Xiaomi smartphones have a Mi Account binding to a hardware ID. Changing the IMEI does not untie the device from the owner's account if the Find the Device feature is enabled. This protects against theft, but complicates repairs.
