How to change the IMEI to Xiaomi: Truth, Risks and Consequences

The question of how to change IMEI to Xiaomi often arises among users who have faced a device lock by an operator or bought a device from a “gray” market where identifiers could be lost when flashing. IMEI (International Mobile Equipment Identity) is a unique fifteen-digit code assigned to each communication module in the factory, and theoretically it should not change throughout the life cycle of the gadget. However, technically advanced enthusiasts and masters of service centers know that in the chips MediaTek and Qualcomm, there are engineers used in the Redmico data and recordings.

Despite the technical possibility of interfering with system files, the procedure for changing the ID involves enormous risks, which are rarely discussed in public sources. Attempting to write a new code can lead to a complete failure of the communication module, turning the smartphone into a device that only works on Wi-Fi, or worse, to locking at the level of the manufacturer’s servers. Below we will discuss in detail the mechanisms of these identifiers, software methods of influence and the real consequences of such actions for the average user.

There is a common misconception that change IMEI Helps bypass the lock on the stolen phone. In fact, in most countries of the world, including Russia and the EU, manipulation of the unique identifier of equipment is illegal and prosecuted by law, as it allows you to hide the location of the device and bypass the bans of operators. NVRAM-It is worth weighing all the pros and cons, and also to understand that modern telecom operators have learned to track such substitutions.

⚠️ Attention: Change IMEI-The Code of Administrative Offences in the Russian Federation and many other countries is an administrative offence. Article 13.3 of the Administrative Code of the Russian Federation and similar legislation prohibit the use of radio electronic means with changed identifiers.

What is IMEI and why is it important for Xiaomi?

IMEI is your smartphone’s digital passport, without which you can’t connect to your cellular network. This code is stored in a special secure partition of memory, which in the Qualcomm processor architecture is called NVRAM, and in MediaTek – NVM. When you turn on the phone, the modem reads this data and transmits it to the nearest operator base station for authorization on the network. If the code does not match the GSMA database or is marked as invalid, access to voice and mobile Internet will be limited.

For Xiaomi ecosystem owners, this parameter is also critical because it is tightly tied to the Mi Account and device search system. In the event of a device being stolen or lost, it is IMEI that police and operators can try to track the location of the device even if the SIM card has been replaced. In addition, technicians first check the code on the box, in the system settings and in the firmware when contacting the service center for warranty repair.

Modern smartphones, especially the flagship models of the Xiaomi 13, Xiaomi 14 or Poco series F5, Often have two slots under SIM-The maps, and therefore two unique ones. IMEI. Violation of the integrity of these records can lead to chaotic behavior of the communication module: constant network searches, rapid battery discharge due to overheating of the antenna module or complete disappearance of the signal. Android security system can also consider changing system files as an attempt to hack and block the work of banking applications.

Legality of procedure and legal consequences

Most countries consider IMEI to be an integral part of hardware, similar to a car license plate, which is equivalent to forging identification plates. Russia imposes liability for using devices with changed identities, and telecom operators have the right to block such devices from their networks without the possibility of unlocking, this is done to combat theft and “gray” imports of equipment.

There are also international databases where operators enter IMEIs of lost or stolen phones. If you try to clone code from another clean phone, you automatically become complicit in a crime because your phone will be listed as a hijacker. Communications operators use sophisticated traffic analysis algorithms that easily detect cloned IMEIs if two devices with the same code appear on the network at the same time or in close geographic locations.

• 🚫 Device lock: Operator can permanently lock the phone IMEI, And it's going to become a media player.
• ⚖️ Legal liability: The owner may face a fine or other penalty for using modified equipment.
• 📉 Loss of value: Phone with "broken" or modified IMEI It is impossible to sell at the market price as customers check the history of the device.
• 🔒 Warranty problems: Official Xiaomi services will refuse repairs, finding a mismatch between software and hardware identifiers.

It is important to understand that even if you can technically change the code, the device will legally remain “labeled.” Communication operators keep connection logs, and anomalies in the behavior of the device (for example, a sudden change in the model of the phone on the network with the same IMEI or vice versa) immediately attract the attention of automatic security systems, so before starting any manipulations, you should think about the feasibility of such actions.

Software methods and necessary tools

If the legal aspects are considered purely from a technical point of view, then changing the IMEI on Xiaomi devices requires obtaining superuser rights (Root). Without root rights, access to the system partitions where the modem data is stored is closed. The process usually begins with unlocking the bootloader through the official Mi Unlock utility, which in itself can lead to deleting all data from the device and resetting settings.

After obtaining root rights (most often through Magisk), users turn to specialized software. Software like SN Writer, Maui Meta or MCT Bypass is popular for MediaTek processors. Qualcomm devices, which make up the lion’s share of Xiaomi’s market, use QPST (Qualcomm Product Support Tools) and QCN Writer tools, which allow you to directly interact with diagnostic ports and write new values to memory cells.

An alternative, but less reliable method is to use applications from the Play Market, such as IMEI Changer or Xiaomi IMEI Repair. However, the effectiveness of such applications on modern versions of Android (11, 12, 13 and above) tends to zero, as Google and chip makers have increased the protection of system files.

adb shell


su




echo"new_imei_value" > /dev/block/bootdevice/by-name/modem_fs1

The above is an approximate view of the command for the terminal that advanced users are trying to use. However, in reality, the file structure depends on the specific model and version of the firmware. An error in addressing can lead to the modem "bricking" after which the phone will no longer see the SIM card at all, in which case recovery is possible only through a deep memory dump and the presence of the original QCN or NVRAM file saved before the intervention.

Engineering menus and hidden commands

Many users are looking for simple ways to change code through the engineering menu by entering special combinations in the “ringer.” For devices based on MediaTek, there was a command ##3646633## that opened access to hidden settings. In theory, you could find a tab “Connectivity” or “CDS Information” and write a new IMEI. However, on modern Xiaomi smartphones with the shell of MIUI and HyperOS, this input is often closed or does not contain editing fields.

For Qualcomm processors, the analogue was the command ##717717## or access via the debugging menu. But even if you manage to log into the engineering menu, the IMEI fields there tend to be blocked (“gray”) without special rights or patches. Attempts to use third-party applications to activate these fields (IMEI Enabler) often lead to unstable system operation.

It is worth noting that on dual-symbol devices, it is important not to confuse IMEI 1 and IMEI 2. Incorrectly writing data to the corresponding cells can cause one of the slots to stop working, or the phone will constantly switch between 2G/3G/4G networks without stabilizing. The engineering menu also allows information about the radio module, which is useful for diagnosis, but dangerous for editing without deep knowledge.

Using an engineering menu without understanding the settings can cause all network settings to reset. If you accidentally change the frequency bands or the modem region, the phone may stop catching the 4G/LTE network in your area. It can be extremely difficult to restore the factory settings of the radio module after such experiments, often requiring a flashing of the entire device with cleaning of all partitions.

💡

Before any manipulation of the engineering menu, take a picture of all the current values on the screens. This is the only way to get it back to normal if something goes wrong.

Risks and possible problems after the change

The worst consequence of a failed change IMEI The modem may go into a state where it doesn't see any SIM card, or it constantly requires input. PUK-In the worst case, the modem bootloader is damaged and the phone stops turning on, stuck on the Redmi or Poco logo.

Another problem is conflicts with Google services and banking applications. Android security (SafetyNet / Play Integrity API) checks the integrity of the system partition. If it is found that IMEI is changed or root rights are active, applications may refuse to work. You may face the inability to pay for purchases through NFC (Google Pay / Mir Pay), since card tokenization requires a secure environment.

⚠️ Attention: After shift IMEI If the phone is stolen, you can't track it or remotely lock it, because the server can't correctly identify the device.

Also worth mentioning is the twin problem: If you took an IMEI from another randomly selected phone, there is a high risk that the code is already blacklisted or used by the real owner, in which case your phone can be remotely locked as soon as the owner of the original reports the problem, or you start receiving other people's SMS and calls intended for the owner of that IMEI.

How to find out and check your current IMEI

Before you decide to take any action, you need to know exactly the current status of your device. The easiest way to know the IMEI is to dial *#06# in the phone app. This code works on all Xiaomi devices without exception and displays information about all available slots. Compare these numbers with those shown on the box and on the sticker under the back cover (if it is removable) or in the sim card tray.

For a deeper check, you can use online IMEI verification services. There are GSMA databases and various aggregators that will show the device model, release date, country of origin and lock status. Type the code into the search bar on imei.info or similar site. If the service shows that the phone is wanted or has a changed identifier, this will be visible immediately.

You can also find this information in the settings of the smartphone itself. The path usually looks like this: Settings → Phone → General information. This shows the data that the operating system sees. However, remember that if the IMEI has been changed software, then both the settings and the code type will show a new, left-handed number, not the factory number.

💡

Always check IMEI in settings, when typing *#06# and on the physical case sticker, and the coincidence of all three values is a sign of a serviceable and clean device.

Restoring the factory IMEI

If you do have problems after experimenting, the only safe way to do this is to restore the original ID, which requires a pre-saved backup of the EFS or Persist partition. If there is no backup, recovery is extremely difficult. In some cases, factory resets help, but this rarely works, since data in NVRAM is often not affected by a conventional reset.

For device owners on MediaTek, flashing stock firmware through SP Flash Tool with the “Format All + Download” tick sometimes helps. However, this action completely erases all data and may require authorization through Mi Account. Qualcomm devices often require the use of paid service programs (DC-Unlocker, Chimera), which can read IMEI from the manufacturer’s server if the device was previously registered.

The best way to avoid problems is to not change the IMEI without an urgent need. If the phone is blocked by the operator, it is more legal and safer to contact the communication salon to unlock for a fee than to risk the performance of an expensive gadget. If you buy a used phone with a “broken” IMEI, the only way out is often to use the device as a tablet over Wi-Fi.
