How to erase Xiaomi IMEI: risks, consequences and methods of resetting

The question of how to erase Xiaomi’s IMEI is often raised by users who have faced an IMEI lock, the need to change region, or the desire to reflash the smartphone for specific tasks. IMEI (International Mobile Equipment Identity) is a unique mobile hardware identifier that is written in the memory of the device in the factory. In theory, this number should be immutable, but in the Android environment, and especially in the Xiaomi ecosystem, there are ways to interfere with the system partitions where this information is stored.

It’s worth noting that the process of changing or completely removing IMEI is not a regular function of the operating system. Smartphone manufacturers implement various layers of protection to prevent ID swapping, as this is often used to bypass locks of stolen devices. On Redmi and Poco devices, the situation is similar to flagship models, but unlocking the bootloader here is easier, which opens up access to deeper system changes.

Before getting into technical details, it is important to understand the legal side of the issue. In many countries, manipulation of IMEI is prohibited by law and amounts to illegal change of labeling. If your device is blocked by a carrier due to loss or theft, trying to change the ID can be considered a crime by law enforcement. Complete removal of IMEI leads to the inability to register in the networks of mobile operators, turning a smartphone into a tablet without the possibility of calls.

Technical consequences of removing IMEI

Users who are experimenting with partition systems should be aware of the scale of the consequences. IMEI — It's not just about changing the number in the About phone settings, it's about affecting the radio module of the device that communicates with the base stations, and without the correct modem ID, the processor won't be able to log in to the operator's network, even if it's not the right one. SIM-card.

In addition to losing communication, there may be problems with Wi-Fi and Bluetooth. MAC-addresses of wireless modules are generated or linked based on the basic IMEI. If this base number is zeroed or damaged, you may find yourself in a situation where the wireless power sliders become gray and inactive.

⚠️ Attention: After erasing IMEI service centers often refuse warranty service, as this is considered a violation of the integrity of the software shell and interference with the work of the hardware.

Also worth mentioning are location issues: geolocation services like Google Maps or Find Device may not work properly, as they use a combination of GPS and cell tower data to better position. Without logging in to a cellular operator's network, the accuracy of positioning will be significantly reduced.

Recovery after a failed erasure attempt is not always possible. If the NVRAM (Non-Volatile Random Access Memory) partition, which stores antenna calibration data and identifiers, is damaged, simply flashing the stock firmware may not help, you will need to have a backup copy of your device or contact specialists with programmers.

IMEI Change Methods on Xiaomi Devices

There are several approaches to changing or deleting an identifier, each requiring preparation and carrying different risks. The most common method involves using an engineering menu, but on modern versions of MIUI and HyperOS, access to it is often closed or restricted.

Access to hidden features often requires entering special codes into the Phone app. For example, code ##3646633## should open the engineering menu, but on Xiaomi global firmware it often doesn't work without modifying system files. ADB-commands that allow you to send requests directly to the system.

A more advanced method involves using specialized software such as Maui Meta or SN Writer in conjunction with MediaTek drivers (MTK), which is only relevant for devices built on MediaTek processors. Snapdragon-based devices require other tools, often paid and only work with authorized service center accounts.

If you do decide to proceed, you will need an unlocked bootloader. Without this step, access to critical memory partitions will be closed. Unlocking the bootloader on Xiaomi devices requires a Mi Account binding and a wait of 7 to 30 days, depending on the region and version of MIUI.

Tools and training required

Preparation for the procedure should be careful, as the error can lead to the "bricking" of the device. You will need a computer with Windows, since most drivers and utilities are sharpened for this platform. USB-cable, preferably original, to avoid connection breaks at a critical moment.

Make sure to back up your data completely. The process will affect system partitions, and loss of personal files, contacts, and photos is almost guaranteed unless you take action early. Use cloud services or local copying on your PC.

It's important to install the right drivers. For MTK devices, these are Preloader and VCOM drivers. Qualcomm might need QDLoader drivers. Without properly installed drivers, the computer simply won't see the phone in the right mode, and the IMEI change program won't be able to connect to the device.

Don’t forget about security risks. By downloading IMEI modification software from unverified forums, you risk infecting your computer with malware. Many quack versions of software contain Trojans, password-stealing and credit card data.

Step-by-step instructions through the engineering menu

If you're lucky enough to have an engineering menu on your device, this is the easiest way to go: Open the Phone app and type ##3646633##. If you open a menu with tabs like Hardware, Testing, Debug and others, you have access.

Go to the Connectivity or CDS Information tab. You can find the Radio → Phone section. You can select AT+ from the command list that opens. You can change the IMEI by using commands like AT+EGMR=1.7, "YOUR IMEI" for the first slot and AT+EGMR=1.10, "YOUR IMEI" for the second.

After you enter the command, press the Send button. If OK appears in the log, the change has been successful. Reboot the device and check the new IMEI by dialing *#06#. If the number remains old or appears as Null/000000, then the system protection prevented the change.

It is worth noting that on Android 10, 11, 12 and later, this method works extremely rarely without the presence of Root rights and special patches. Android security has become much more strict in controlling access to the radio module.

Use of specialized software and Root rights

The most popular method is Magisk. Once you install Magisk and get Root access, you can use modules that replace IMEI at the system level without affecting the physical chip, which is less dangerous, but also less effective at bypassing carrier locks.

There are applications like IMEI Changer or Xposed IMEI Changer that require an installed Xposed or LSPosed framework, which allow you to change the IMEI system that you display. However, when you reset your settings or update your firmware, the changes can fly.

⚠️ Note: Getting Root rights will automatically void the warranty on Xiaomi’s device, and Google Pay (Mir Pay) banking apps and services will stop working unless you use additional root hiding modules (Magisk Hide / Zygisk).

When it comes to fully streaming NVRAM over a PC, the process is more complicated: you need to switch the phone to Meta Mode (for MTK) or EDL Mode (for Qualcomm), and you often need to open the case and close the contacts on the board to log into EDL, which is a last resort.

The software reads the current memory dump, the user edits the hex code, replacing the old IMEI with a new one, and writes the changed file back. Any error in the bits can cause the modem to stop running at all.

💡

Before recording a new IMEI, be sure to write down the original number on paper or take a picture of the sticker under the battery (if it is removable) to be able to return everything as it was.

Restoring the original IMEI

If the experiment fails and the phone stops catching the network, you have to return the factory settings, and the most reliable way is to have a backup of the NVRAM partition made before all manipulations, and if there is no copy, the task becomes more complicated.

In some cases, a full reset via Recovery Mode and a reflash of the official stock firmware via the Mi Flash Tool in Clean All mode helps. However, if the NVRAM partition was physically erased, the software will not be able to restore the unique identifier, since it is not stored on Xiaomi servers in an open form for the user.

The only legal and reliable way to recover from damage is to contact an authorized Xiaomi service center, where engineers can read IMEIs from factory logs by device serial number (SN) and record them again through internal service equipment.

There are also online services that can generate a recovery file by IMEI (if it is readable) or serial number, but their effectiveness is not guaranteed and depends on the processor model.
