No imei after flashing. Restoring IMEI after flashing firmware on an Android device: detailed instructions. Sticker on the packaging or under the removable battery

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 devices, Philips and Fly;
  • *#*#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 engineering menu MTK".

From the name it is clear that the application works correctly only with MTK processors. We will describe how to restore IMEI on Android using this utility if the installer did not enter the code correctly:

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 subsection " Personal Area» or directly follow the link

In this case, you need to check whether the identifier has been lost after an unsuccessful reset or firmware update. To do this you need to do the following:

  • go to the dialing window;
  • dial *#06#;
  • sometimes after this you still need to press the call button.

If all is well, a 15-digit code will appear on the screen, this is the IMEI. Otherwise, there will either be zeros or a message indicating that the code is incorrect or missing.

If it happens that the ID number has disappeared, then you can see it under the back cover. To do this, you need to turn off the phone and remove the battery. Or you can simply find it on the phone box. This will definitely come in handy during the recovery process.

Devices based on MTK processor

Each manufacturer has in its arsenal devices based on MTK processors. If you use just such a device, you can consider yourself very lucky. For MTK, the issue related to IMEI restoration on Android is not relevant. It is enough to use several engineering menu commands. So what needs to be done? Here are step-by-step instructions.

Step #1. Enter the engineering menu code. The default combination is *#*#3646633#*#*. This code allows you to access the phone's engineering menu. Through it, you can delve into previously inaccessible system functions of the device, as well as restore IMEI.

Step #2. Enter the IMEI repair command. With this action, everything is not so simple. Each manufacturer has its own special code.

IMEI repair on Explay smartphones

This Russian manufacturer has been known in the mobile device market for quite some time. Devices from this manufacturer combine an attractive price and high quality. Everything here is almost like the Chinese. In general, there are some similarities between smartphones from Lenovo and Explay. How can I restore IMEI on Explay devices? Everything is the same here as for Lenovo smartphone. Both manufacturers use MTK processors. For this reason, you can use the same method as when restoring IMEI on a Lenovo device, namely the Mobile Uncle Tools program.

You can also try using the original Maui Meta 3G program. You need to download and install the Maui meta 3G program. It is also necessary to install for the device necessary drivers.

Only Samsung decided to hide its phone system from users. This approach, on the one hand, is quite logical - after all, there is no danger that users who inadvertently accessed the firmware will “kill” the phone. Perhaps this is exactly what Samsung engineers were counting on. It is almost impossible to restore IMEI on such a device on your own. You will have to pay a considerable amount for service at a service center.

Repairing IMEI in Chinese smartphones

To begin with, it would not hurt to figure out which smartphones can be classified as purebred “Chinese”. This phrase is usually used to describe cheap copies. expensive smartphones, assembled from cheap components by Chinese workers. Such a smartphone is usually distinguished by a “crooked” translation of the system into Russian, as well as the presence of many unnecessary additional functions. Quite often, such smartphones have a television receiver. As a rule, the screens in such devices are non-capacitive, so in order for them to function normally, you have to poke something thin into them. But despite this, such devices are sometimes installed Android system. This means that the issue of IMEI restoration is also relevant for such counterfeits.

Separately, it is worth noting that IMEI restoration for Chinese phones the process is quite complicated. If there is at least some logic in the construction of system folders of “normal” mobile devices, then in the case of Chinese smartphones it is completely absent. Much easier to download required file from the Internet. If the required firmware for a smartphone is found, this does not mean that the difficulties are over. The thing is that cheap Chinese smartphones are connected to a computer using USB cable, and for firmware you will need a cable with a different pinout. This means that you will have to solder with your own hands. On specialized Internet resources you can find the correct wiring diagrams for certain smartphone models. When the cable is unsoldered and the required firmware is found, the task of IMEI repair will be significantly simplified.

One of the unique numbers assigned to each Android device is called IMEI. It can be used for personal purposes, restored or exchanged for Android. It is also worth always remembering why it is needed and knowing when IMEI may be required.

What is IMEI of a smartphone or tablet

IMEI is a unique identifier that every Android phone and tablet has. It is needed so that the device can make calls, send messages and use Mobile Internet. That is, if you have an IMEI, you can use all the functions that the SIM card provides.

How to find out device ID on Android

There are two ways in which you can find out the IMEI of your phone or Android tablet: By entering a USSD code or a sticker located on the back of the device.

Via USSD code

  • In the input section telephone number write the code *#06#.

    Enter the code

  • In the window that opens, you will see one unique IMEI if your device supports one SIM card, and if two, then two IMEIs will appear on the screen.

    How to change IMEI or restore it if it’s lost

    After flashing the device firmware, updating or resetting data and IMEI settings may get lost or disappear. If this happens, you will not be able to use mobile communications, Internet and messages. In this case, there is only one thing left to do - restore the unique number by changing it to another code. This can be done using the built-in engineering menu or through third-party applications.

    How to write code through the engineering menu

  • Remove the SIM card from the device.

    We take out the SIM card

  • Open phone dialing apps.

    Finding a stolen or lost phone by IMEI

    Since the IMEI code is unique, a purely theoretically lost device can be found by contacting law enforcement agencies or your mobile operator. But this method of searching for a device in most cases does not help, since it is quite difficult to get the operation started, and the fraudster who stole the phone most likely changed the IMEI a long time ago.

    The only thing left to do is to enter your IMEI into a single database (http://sndeep.info/ru/lostolen) and declare the device associated with this code as missing. If you add a reward message for finding and returning the phone, you may be able to get it back. Most often, sellers of stolen equipment check this database, so maybe you will get lucky.

    We enter the IMEI of the lost device and other necessary data

    Under no circumstances should you access websites that offer the opportunity to find a device by IMEI for a certain amount of money. Only telecom operators and law enforcement agencies have access to search by code; all other organizations simply do not have access to necessary programs and equipment, which means they won’t be able to find your device and take your money.

    Is it possible to remove IMEI?

    Some users mistakenly think that by erasing the IMEI they will make their device secret and will not be able to make calls to it. But this is absolutely not true, especially since you cannot delete IMEI, you can only change it to a different combination of numbers. How you can change the IMEI code is described above in the article.

    Each Android device is initially assigned its own unique IMEI code, which can be viewed, restored or changed. To do this, you will need knowledge of special USSD codes, an engineering menu or root rights. You can find a lost device by IMEI only with the help of a telecom operator or law enforcement agencies, but not through Internet sites that offer this service. You cannot delete IMEI, you can only change the code numbers.

    On Android - a serious error due to which the device loses the communication signal, which leads to the inability to make a call, send a message or access the Internet.

    Reasons for the failure:

    • Incorrect device firmware.
    • Error when returning the smartphone to factory settings.

    Some models Chinese smartphones they can work without an identifier, but if you have a high-quality device from a well-known brand and your Name has disappeared, the device will not work correctly.

    Manual recovery

    Dial on Android phone combination *#06#. If the IMEI code does not appear on the screen, then you urgently need to restore it. You can find the identification number on the box, in the instructions, or under the battery. If the smartphone supports dual SIM cards, then two IMEI numbers must be specified.

    Manual IMEI repair on Android:


    If the number above does not work, try the following options:

    If your Android supports two SIM cards, then you need to repeat the procedure for restoring the identification number. For the second SIM card the command will be: AT+EGMR=1.10,“IMEI”.

    After recovery, you need to exit the engineering menu and reboot the phone. After turning on, dial *#06# again to check IMEI. If the number is not displayed, then to correct the error you will need an Android IMEI repair program.

    Software recovery

    If manual recovery did not help solve the problem of missing identifier after flashing, then try using the MTK65xx.zip program.

    After rebooting the device, dial *#06#. The device identification number lost after the firmware update will be restored. If the above methods did not help you figure out how to restore IMEI on Android after flashing, then try another option:


    Using Root Browser, move the MP0B_001 file to the /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001 directory. After transferring the data, restart your phone and check the identification number again - this time it should be displayed correctly.
