IMEI is a unique set of 15 digits that is assigned by the manufacturer to each mobile phone and serves to identify the device in the GSM network. Often, owners of Chinese devices of dubious origin are faced with the absence of this code on the device. And after a backup or IMEI it can also crash. And this often affects the quality of communication on a smartphone. Let's figure out how to change IMEI on Android if there is poor GSM network reception or restore serial number after erasing it.

How to determine IMEI on a smartphone

Before changing the IMEI on an Android device, you need to find out the IMEI that was assigned to this device by the manufacturer. This can be done in several ways:

Once you have managed to find out the id, you can proceed directly to changing it.

Ways to restore IMEI

There are two ways to restore or change IMEI on Android:

1. . Like , it is provided on all devices running Android.
2. Using additional software. Among the programs that allow you to register new IMEIs, we should highlight Mobile Uncle and Xposed IMEI Changer.

Changing IMEY through the engineering menu

The engineering menu is used for testing and optimal settings mobile devices. This area is hidden, but can be activated using certain USSD commands entered through the standard dial pad. U different models For smartphones, these commands may differ. For example, for an HTC phone, the combination *#*#3424#*#* or *#*#8255#*#* will be relevant. For Samsung, the command *#*#4636#*#* or *#*#197328640#*#* is suitable.

After changing the IMEI, proceed as follows:

For the changed settings to take effect, the smartphone must be restarted. After you have succeeded in changing the IMEI, you can verify the positive result using the same command *#06#.

Changing the ID through additional software

Using specialized software requires superuser rights on the phone. They can be activated using the programs Romaster SU, UniversalAndRoot, Farmaroot, etc.

So, to open extended access on a mobile device via Farmaroot, you need to:

Changing your IMEI using Mobile Uncle

This program for changing IMEI is freely available, so you can easily download it from Play Market. It works like this:

After you have succeeded in changing the IMEI on your Android device, it is better to close the superuser rights and completely remove the Farmaroot program from the smartphone.

Using the Xposed IMEI Changer utility

The Mobile Uncle application allows you to change the IMEI only on devices running MTK series processors. If you need to install IMEI on Android after flashing a phone with a processor from a company, for example, Qualcomm, the Xposed IMEI Changer program comes to the rescue. The procedure will be as follows.

Have you flashed your Android smartphone and it stopped seeing the network? Did you buy a second-hand device that periodically loses the network and cannot make calls? Are there incoming calls, but outgoing ones are constantly being dropped? Smartphone does not receive or send SMS? All these errors are in one way or another related to the wrong IMEI - “empty”, zero or non-unique. In our guide, we will tell you what to do to prevent damage to IMEI, how to check IMEI on Android and, most importantly, how to restore or change it if trouble does happen. We will also consider situations when it is necessary to change IMEI while remaining within the legal framework.

What is IMEI and how to find it?

IMEI (International Mobile Equipment Identity) is an international identifier for mobile equipment. This 15-digit number is essentially a serial number. mobile device. But unlike the serial number of a car, refrigerator or laptop, this identifier is actively linked to network protocol GSM and it is with the help of IMEI that the cellular network identifies your smartphone. Every time your device moves from one base station to another, it broadcasts the IMEI and the station registers your device, allowing it to work. Or not allowing it if there is something wrong with IMEI.

How to view IMEI

1. The easiest one is to open the battery compartment cover, remove the battery and look at the IMEI on the sticker. The method will only work if the smartphone has not been flashed, because... with firmware that affects the EFS partition (we'll talk about it later), the IMEI will probably change.
2. If the smartphone has been flashed or its battery is non-removable, then the first method will not work. In this case, we use the universal USSD request, which works on any platform: Android, iOS and even simple dialers. Open the “phone” application, select dialing using the keyboard and enter the request: “*#106#”. The smartphone will display a window with its IMEI. If the device has two SIM cards, the IMEI for each of them will be displayed.
3. In the operating room Android system IMEI can also be viewed in system settings. Go to the menu, then - -
4. You can view IMEI on Apple devices in a similar way: - -

The skills to view IMEI will be very helpful when buying a smartphone in person or at an online flea market. After all, it is much easier not to buy a device with a “crooked” IMEI than to then spend time and money bringing it back to normal.

Why does the ID disappear?

The reason for the disappearance of IMEI may be software or hardware problems, depending on the model and manufacturer of the device. But common problems look something like this:

• IMEI disappeared when flashing the smartphone or resetting it to factory settings using the service utility. The problem is especially common in Chinese smartphones based on MTK processors. With ill-conceived firmware (or firmware assembled from someone else's device), you can overwrite or erase the EFS partition, which contains such important data as IMEI, MAC address of the Wi-FI wireless adapter, BlueTooth identifier. After such unsuccessful firmware, not a single wireless interface will work on the device;
• The smartphone was repaired, where the radio module was re-soldered, and along with it the EEPROM with service information. As a result, the device’s IMEI is incorrect or empty;
• IMEI was deliberately reset by the previous owner. This often happens with devices with a dark past. In the best case, the IMEI is erased to bypass the operator lock, which is typical for contract smartphones, and in the worst case, the device is stolen. If the sticker in the battery compartment is missing or damaged so that the numbers cannot be read, the smartphone is 100% stolen. not the previous owner, but the one before last and it is better not to mess with such a device. Read the Criminal Code.

How to restore or change IMEI on Android

Now we will consider a situation where the IMEI was not reset intentionally, there is a sticker with the code - therefore it is known to us. For owners of devices whose battery cannot be removed, I strongly recommend writing down the IMEI, serial number, MAC address of the network card and saving this information in a safe place.

Using the engineering menu

1. Turn off your smartphone and remove the SIM cards from it;
2. Turn on the power, launch the “phone” application and enter the access code into the engineering menu. Depending on the device manufacturer, the code may vary. For example, for Samsung smartphones the code will be<*#*#4636#*#*>. After this, the device will launch the engineering menu, in which we will change the IMEI.
3. Go to the tab , and in it - to the section
4. In the next window, go to the menu item
5. Select menu item In the input field, immediately after writing “AT+”, add the following command:

   EGMR=1.7,”IMEI”,
   where "IMEI" is the number that we need to restore.
   After entering the number you need in the field, click the button<Send at command>. If the command is not executed, try adding a space immediately after “AT+”.

6. If the smartphone has two SIM cards, step 5 must be repeated, but the command will be different:
   AT+EGMR=1,10,“IMEI”
7. <*#106#>

The codes for entering the engineering menu are different for different manufacturers. Here is a table with the most famous

Via Android applications

If it was not possible to restore IMEI using the engineering menu, on smartphones with a processor of the MTK family (most of the Chinese devices) you can use a program specially written for this - MTK65xx.

How to change IMEI using a file manager and Root access

This method is the most complicated, but it works without problems on almost any smartphone running the Android system.

1. Make sure your smartphone has Root access.
2. Download and install any file manager on your device, for example ES Explorer.
3. Download the Restore IMEI archive to your computer.
4. Unzip the archive to a folder on your hard drive. Find the “run.cmd” file in the folder and open it with Notepad.
5. Instead of the numbers following the program name “imei.exe”, enter the IMEI code you need. After that, save the file and close Notepad. Run the “run.cmd” file by double-clicking.
6. If you did everything correctly, it will appear in the folder new file- “MP0B_001”, which we will need to copy to a specific folder on the smartphone.
7. Connect your smartphone with a cable to your computer. Copy the configuration file to microSD card smartphone or to any folder in the user section.
8. Launch on your smartphone file manager ES Explorer. Move the configuration file copied from your computer to the address “/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001”. The system will issue a warning that the file will be overwritten. Agree to this by clicking the button<ОК>
9. Reboot your smartphone and check the IMEI when USSD assistance teams<*#106#>.

Changing IMEI - why is it necessary?

Changing the IMEI code is done in the same way as restoring, just instead of the “native” code, you enter the one you need. And this has to be done for several reasons:

• bought a smartphone with a “blank” IMEI;
• want to remove the IMEI lock from a contract device;
• arrived in a country where foreign IMEIs are blocked (for example, Turkey).
• you need two devices with the same IMEI, which will work in turn.

As a new IMEI code, it is best to choose codes from old non-working ones mobile phones, of which there are always a couple or three at home. If you generate a code using a generator program, there is a chance that someone will already have the same IMEI when trying to register in cellular network your smartphone will display an error.

Let me also remind you that changing IMEI for fraudulent purposes or on stolen/found devices is a criminal offense. Be clean before the law.

How to find a stolen smartphone by ID

From the technical side, there are no problems finding a stolen (lost) device: base stations operator mobile communications using triangulation, they can determine the location of the smartphone with an accuracy of up to 10 meters. And it’s also easy to see from billing which number is associated with a given IMEI.

But the mobile operator will carry out such search activities only at the request of law enforcement agencies. Therefore, the simplest and quick way find a stolen smartphone by IMEI - contact the police. But keep in mind: the first thing they will do when buying stolen devices is to change the IMEI.

Is it possible to remove IMEI?

IMEI cannot be removed. But when changing IMEI, you can make it with zero values. A device with a zero IMEI will not register in the operator’s network, and accordingly, it will not be able to work as a phone or modem. Such manipulation may be necessary if you need to limit the functionality of a smartphone or tablet for children, for example, so that they use the device only as a media player. Or for company employees who need to limit Internet access to a corporate channel with configured blocking and a blacklist of sites.

I would also like to add that on almost all models Apple smartphones, on the top Samsung smartphones and Sony software changing IMEI is not possible. It is necessary to reprogram the EEPROM of the radio module, which can only be done in service center using specialized equipment.

All methods of changing or repairing IMEI seem simple, but the variety of hardware configurations of smartphones makes such work difficult. Carefully select the necessary tools, study the experience of working with similar smartphones on specialized forums and luck will definitely smile on you. If the problem cannot be solved programmatically, there is always the “cherry on the cake” - a trip to the service center, where professionals will be happy to help you.

IMEI sometimes “flies” when flashing the gadget, after which the latter stops working correctly, losing the ability to make calls and go online. Note that some Chinese devices can operate without an identification number, but such devices are in the minority. Therefore, we will tell you how to restore IMEI on Android, as well as how to change it if necessary.

To make sure that it is the lost identifier that is causing problems with the gadget, enter the characters *#06# in the dialing field. If the code of your device does not appear on the display after this, then the problem has been identified correctly - you need to restore the IMEI. Keep in mind that a phone with two SIM cards must also have two IDs.

Let's describe how to restore IMEI on Android after flashing the firmware using Samsung as an example:

1. Remove the SIM card from the device.
2. , for which in the field for entering the number, write the combination *#*#4636#*# or *#*#8255#*# if the first code is incorrect.
3. Open the “CDS Information” section, then “Radio Information” and go to the “Phone 1” subsection.
4. In the top line where it says “AT+”, enter the command EGMR=1.7. Next, in quotation marks, we write the fifteen-digit code corresponding to your IMEI.

Please note that the codes for entering the engineering menu differ on different devices. For Samsung they are already given above. Therefore, before changing IMEI, check this information. For other gadgets they may be as follows:

• *#*#2846579#*# - for Huawei gadgets;
• *#*#3646633#*# - for Alcatel, Philips and Fly devices;
• *#*#8255#*#, *#*#3424#*# - for HTC;
• *#*#7378423#*# - for Sony.

You can restore the ID not only manually, but also using various utilities that allow you to enter the engineering menu without entering a code. For this, for example, the MTK Engineering Mode program can be used, available even in Google Play. True, it only works with MediaTek processors.

Let us immediately note that changing the device identifier is not legal, since it will be very difficult to find a lost or stolen gadget using IMEI. Let's describe how the Android IMEI is changed if, for example, you find someone else's device:

After this, all you have to do is dial *#06# to make sure that the identifier has really changed. If you want to return your old imei and don’t know how to find the fifteen-digit code, then if you have the device itself, it’s very easy to do. The codes are located on the box and in the gadget itself on a sticker under the battery.

Mobile Uncle is another small utility that can be used to change IMEI if you have Root rights. It is available on Google Play and has a long name there “Launch the MTK engineering menu”.

Note that these methods describe how to restore IMEI on Android after flashing, that is, if it was lost after unsuccessful user actions. It is required to register a new one only in cases of an attempt to conceal illegal actions with the gadget. Moreover, there is a very high probability that if you change the “native” identifier to a changed one, the smartphone will turn into “ ”, losing the ability to access the Internet, make calls, send messages, etc.

But even if you cannot find out the IMEI, for example, in the event of a gadget theft, it is easy to obtain it in your Google account to transfer information to law enforcement agencies. This method works if the device is connected to a Google account. All smartphone data is automatically saved on the server, and to get it, you need to go to the Google account settings section in the “Personal Account” subsection or immediately follow the link
