Restoring imei using the terminal. Ways to repair or replace IMEI in Android devices. Repair IMEI in Chinese smartphones

When buying a used phone or an unsuccessful firmware, you may experience problems connecting with mobile network. The reason for this is the flown IMEI, which is very easy to restore.

International Mobile Equipment Identifier. When your phone connects to a mobile network, it transmits two primary identifiers - your SIM card number and Phone IMEI. This is a fifteen-digit code of decimal digits: from the first to the eighth - the model and place of origin, after - the serial number, and the last digit - the control, calculated by the Luhn algorithm based on the previous ones.

At a time when phones still had buttons, IMEI was the very beacon by which the police found stolen phones. With the advent operating system Android, which gives the user full control over the device, IMEI has ceased to be a stigma and has become a setting that can be very easily changed or lost under unfortunate circumstances.

To find out your IMEI, dial the number on your phone: *#06#.

Or look it up in the settings.

The IMEI should be listed under the cover of your device, most often under the battery and on the box you bought it in.

Why IMEI flies and how to restore / change it

The main reason for the loss of IMEI is an unsuccessful phone firmware, a little less often - an attempt to obtain root rights.

As mentioned above, IMEI is one of the main identifiers of your phone when communicating with a mobile network. And if it crashed (all values ​​are set to 0), there may be communication problems.

If you bought a used phone and found a discrepancy between the IMEI indicated on the phone and the one registered under the battery, it is better not to set the original IMEI.

Things to remember about IMEI:

• deleting IMEI is changing IMEI to a zero value (000000000000000), restoring IMEI is changing IMEI to its original value;
• there are no ways to restore the original IMEI if you do not know it, since information about it is not stored anywhere;
• if it is not possible to determine the original IMEI, you can always invent or generate it;
• in no case do not trust services that offer to find out your original IMEI for recovery - these people are scammers and offer the impossible;
• The only way to find your missing/stolen phone by IMEI is to contact the police.

Recovery through the engineering menu

To change IMEI, you will need to log into engineering menu. You can enter it by dialing a special number on your android device. The most common number to enter the engineering menu is *#3646633#*. And if it doesn't work for you, try these:

In addition to the above list, the number to enter the engineering menu must be indicated in the instructions for your device.

Repair IMEI using applications

If you have difficulty entering the engineering menu, or the engineering menu is not available on your device, you can always change the IMEI using applications. As mentioned above, the last IMEI digit is a control one and is generated by the Luhn algorithm based on the previous ones. And if you want to register a non-native IMEI, then it is better to generate it using one of these applications.

To download the application for changing IMEI, go to Play market and enter the word IMEI in the search bar.

All found applications for changing IMEI are identical, and we will consider them using Chamelephone as an example. It is worth saying that each of the applications requires root rights, and this is another story.

Getting root rights

Root rights or superuser rights grant the user special powers, such as:

• deleting system files;
• embedding programs and melodies;
• removal of ads;
• processor overclocking;
• activating hidden Android features.

Root rights will be required for some subsequent actions when cleaning the device. Rooting will void your device's warranty. Each device has its own characteristics, and the risk of damaging the system when rooting or after is always there. If you have root rights, you will not be able to receive warranty updates for the operating system.

1. If you haven't installed apps from external sources before, go to Android settings and open the "Security" tab in the "Personal data" section.

   

2. Activate the "Unknown Sources" option.

   

3. Download from the Internet latest version Framaroot. This application has analogues in the Play Market, but they may not be as reliable.
4. Install Framaroot. If the installer blocks the process, select "More Information" and click "Install Anyway (Insecure)".

   

5. Launch Framaroot and select "Install SuperSU", then click on any of the methods for obtaining root rights. Once received, reboot your device.

   

6. There is a possibility that your device is not supported by this app. You can try alternative programs, but this will increase the risk of "dropping" your system. It is best to find out the individual method for obtaining root rights for your device.

Sometimes owners of Chinese smartphones are faced with a reset problem IMEI. This mainly happens when applying "Return to factory settings". If not IMEI- the phone loses the GSM signal, it does not receive calls and does not make outgoing calls. The operator and communication signal may even be displayed: MTS, Kyivstar, Life, etc., but will not receive or call. Some models will display "IMEI invalid" or "IMEI missing" for both SIM cards.

You can confidently determine if there is an IMEI by typing *#06# in the dialing menu . The screen will show IMEI: "15 digit code" or not. (sometimes you need to enter *#06# and press call).

It seems like a big problem, especially when the service takes a lot of money. However, the procedure itself to restore IMEI in the phone is simple and fast.

Here are ways to restore IMEI on Chinese smartphones. If you plan to use them, understand that phones and firmware are different, the described examples may not be suitable for your phone, and an incorrect change in the engineering settings on your own may lead to incorrect operation, debugging the device and removing it from warranty service, act at your own peril and risk. The author is not responsible for the application of this manual.

Initially, you need to check the IMEI - dialing * # 06 # call

Method 1

If there is no IMEI, you need to do the following to restore it:

1. Turn off and remove SIM cards. Rewrite 15 digits of IMEI, they are indicated on the back of the phone under the battery, if the phone is non-separable, like a copy of the iPhone 5, look at the warranty card or on the box. Turn on your phone.

If nothing happened, try the following codes to enter the engineering menu.

• *#*#54298#*#* or *#*#3646633#*#* - MTK processor
• *#*#8255#*#*, *#*#4636#*#* - replace imei with Samsung
• *#*#3424#*#*, *#*#4636#*#*, *#*#8255#*#* - replace with HTC
• *#*#7378423#*#* - replacement for Sony
• *#*#4634#*#* - replace imei with iPhone 5C Android
• *#*#3646633#*#* - replacement for Philips, Fly, Alcatel
• *#*#2846579#*#* - replacement for Huawei

3. Menu item d: CDS Information > Radio Information > Phone 1

4.Place the cursor after AT+ and enter EGMR=1.7,"" using english alphabet. The system will suggest the option EGMR=1.7,"" select it, or enter the characters yourself.

5. Put the cursor in quotes and enter the IMEI code, i.e. 15 digits. There should be an inscription: AT+EGMR=1,7,"123456789101112", Where 123456789101112 - 15 digit IMEI.

7. If the phone is for 2 SIM cards, to restore the second IMEI, repeat steps 5 and 6 with only the code AT + EGMR = 1.10, "123456789101112", where 123456789101112 is 15 digits of the IMEI of the second SIM card.

8. Exit the engineering menu and reboot your phone.

9. Check IMEI code - *#06#. The entered code should appear on the screen.

10. Turn off and insert SIM cards into your phone. Try to make calls, the phone will work.

If IMEI recovery failed, then either something was done with an error, or this method is not suitable for your device. Don't change any other settings unless you're sure where this will lead. This can lead to incorrect operation or failure of your device.

Method 2

1. Download MTK65xx.zip archive or MTK65xx.apk file

2. Extract the application from the archive

3. Remove SIM cards from the phone

4. Install the application on your smartphone

5. The first time you launch the application, it will notify you of the type of your Android devices, after reading, press the button ok

6. The application reads IMEI, if it did not count, press the read button

7. Uncheck "same IMEI" and enter new IMEI.

8. Press the "logout" button. Reboot Android device

Method 3

Owners of Chinese Googlephones based on MTK6515 may encounter the problem of losing IMEI as a result of flashing or resetting to factory settings. As it turned out, the problem is typical for firmware, where the file "MPOB_001", with encrypted IMEI, located in /data/nvram/md/NVRAM/NVD_IMEI, which is overwritten by reflashing. In modern firmware, this file is placed in /nvram/md/NVRAM/NVD_IMEI, it no longer disappears.

If you are not sure about the firmware, before updating / resetting the settings, we recommend that you save this file on a flash card. You can do this using a terminal emulator, for example: Android Terminal Emulator (available on the play store), or Better Terminal Emulator Pro. Run after installation and enter in command line code:

su, and agree to the granting of root rights.

Now the actual procedure for writing IMEI:

echo "AT+EGMR=1,7,"IMEI_1"" > /dev/pttycmd1
echo "AT+EGMR=1,10,"IMEI_2"" > /dev/pttycmd1

Where IMEI_1 and IMEI_2 are 15 digits of the 1st and 2nd IMEI respectively.

Method 4

If IMEI is not in the firmware, but in EEPROM. Then it is very easy to change it with the help of a complete data cable (not a firmware one) and the Hyperterminal program, which is included in any Windows.
Instructions for changing IMEI via Hyperterminal:
1) connect the phone in com-port mode to the computer via a USB cord. If you are using Windows: call hyperterminal -> select the virtual port on which the phone is connected, after connecting, type AT - in response, you should receive OK in the window, i.e. connected via comport;
2) then we type a test command (determines whether IMEI change is supported):
AT+EGMR=?
if supported (OK) - drive in a new one
AT+EGMR=1,7,"IMEI"
(instead of IMEI - real imei numbers).

If two-symbol - the second imei is changed by the command AT + EGMR = 1,10, "IMEI"
(instead of IMEI - real imei numbers).

By the way, the first parameter of the command is zero-read, one-write.
at+egmr=0.7
+EGMR: "135790246811220" - view the first IMEI

At+egmr=0.10
+EGMR: "135790246811220" - view the second IMEI

If they differ, then by * # 06 # on the keyboard of the device both are displayed, if they match - only one.

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

What is the IMEI of a smartphone or tablet

IMEI is a unique identifier that every Android phone and tablet has. It is needed in order to be able to call, send messages and use the device. Mobile Internet. That is, at available IMEI you can enjoy all the features that the SIM card provides.

How to find out the device ID on Android

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

Via USSD code

Look at the sticker inside the case

Remove the cover of the device and look for a sticker that may be on the case or under the battery. On it, find the IMEI line, which will contain 15 digits.

We look at the IMEI code

How to change IMEI or restore if it has crashed

After flashing the device, updating or resetting data and settings, IMEI may go astray or disappear. If this happens, then you will not be able to use mobile communications, the Internet and messages. In this case, one thing remains - to 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.

Finding a stolen or lost phone by IMEI

Since the IMEI code is unique, it is theoretically possible to find a lost device 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 start the operation, and the scammer who stole the phone most likely changed IMEI a long time ago.

The only thing left to do is to drive 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 message about the reward for finding and returning the phone, then it may be returned to you. Most often, sellers of stolen vehicles check with this database, so you might be lucky.

We drive in the IMEI of the lost device and other necessary data

In no case do you turn to Internet sites that provide the ability to find a device by IMEI for a certain amount. Access to search by code is available only to telecom operators and law enforcement, so all other organizations simply do not have access to the right programs and equipment, which means they will not be able to find your device, while taking your money.

Is it possible to remove the IMEI?

Some users mistakenly think that by erasing the IMEI they will classify their device and it will not be possible to call it. But this is absolutely not the case, 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 sites on the Internet that offer this service. You cannot delete IMEI, you can only change the code numbers.

Modern technical devices that allow us to use communication services, access the Internet, store data, etc. are constantly being modified and acquire either additional features or identification data. This is done in order to store and secure your data, which allows you to restore lost information or find a lost or stolen device in time. But each development is created with good goals and ordinary people, so it is almost impossible to avoid various failures and errors. Today we will talk about how IMEI recovery goes, what is needed for this and why this function is needed at all. The severity of the problem is due to the fact that many users began to face a situation where their device stopped working normally and indicated an error that mentions IMEI. Therefore, in order to understand this problem, you should read this article, which contains all the necessary information that will not only be useful, but also serve as an excellent instruction for restoring your device.

What is IMEI?

But before talking about how IMEI recovery goes, it’s worth understanding what it is. The IMEI is the generic name for your device and is required for conditional registration and provision of various services. For example, it allows you to easily make phone calls and access the Internet, get support and install various applications. In general, this function is the basis of the performance of your device. But is it really so? What is the main purpose of this identification number?

Why is this feature needed?

Oddly enough, but the hidden meaning of this feature is that operators can easily identify you and provide all the necessary information about your calls and correspondence, about Internet preferences and favorite applications. In general, this is your electronic passport, which allows you to find out about the user who uses it, almost everything that is needed. Can this be avoided? Yes, many hackers managed to do this, however, they have to get used to the constant change of data, their complete formatting, etc. Therefore, it is better not to rack your brains and use the main purpose of this function.

How do you know which number you have? It is quite simple to do this, since almost everyone can check the IMEI. It is enough to dial the combination * # 06 # on the keyboard, and the device itself will give out your number, however, if it is activated for you. And it is from this moment that you can understand whether your device is broken, or you can continue to use all the available features without any problems. If an error occurs, and at the same time you notice that you cannot make calls, then you have problems in identification that need to be fixed urgently. What is causing this unfortunate situation? We will talk about this further.

Why does this problem occur?

So, you decided to check the IMEI, but the device does not give it out. Before that, have you noticed that you cannot make calls, write SMS and access the Internet, although you have completely updated the firmware of the device and re-downloaded all applications? This is where the problem lies, due to which this unpleasant situation occurs. Firmware is a process in which the software shell is changed, that is, codes are updated, a new structure is created and some unnecessary processes are erased. This procedure should be done by professionals so as not to damage the device and do everything on highest level. True, many users sometimes decide to personally do this and “crookedly” install this software element, which causes software failures and IMEI is lost. In fact, it does not change, it simply loses its registration force, which causes all the main functions of the device to be disabled.

This is not so critical, since everything can be restored either in a special service, or on your own, using various convenient methods to ensure IMEI recovery on android. What methods exist and how to use them, you can find out below.

Ways to fix the error

After you saw the error, and all the symptoms of an unpleasant situation were confirmed, you should choose a method for solving this problem. Repairing IMEI through the engineering menu, using various programs, downloading a file from the Internet, etc. - there are many ways, however, those listed are the most effective and effective among all. They allow you to access the internal settings of the device system with further editing and changing the structure. These actions allow you to amend and return the IMEI to working capacity. Each method is unique in its own way and has its own requirements that must be followed with special care so as not to aggravate an already unpleasant situation. If you are not afraid of innovations and are ready to take risks, then you can already prepare a notebook and a pencil, but if you suddenly have doubts about your abilities, then it is better to contact the service, as the specialists there will quickly correct the error, and in a couple of days you will be able to continue using your device .

But it should be borne in mind that this service, which allows you to restore IMEI, costs a certain amount of money, so consider in advance what exactly you should use. In the meantime, we will consider the easiest way to fix the error, which is to use a special program.

Recovery using programs

There are many different applications on the network that supposedly can automatic mode fix this problem. But is it worth believing such simple descriptions? Therefore, in order not to be deceived, we recommend using only one application for the correction procedure. The IMEI repair program is called GScriptLite.apk. In fact, this is a common application that allows you to authorize an identification number through an operator request. You need to download the application file to your device and install it. Then you should run the program and add to use a script called "needs su", which has standard IMEI number indicators. Once you have added the script, you need to change its data, where the numbers are indicated, by entering your IMEI (above there is a description of how to find out your identification number). Now it remains only to save the changes and activate the script. The device will ask for permission for superuser rights, which must be approved by clicking on "OK". It remains only to restart the device, and it will be ready for use.

But there is one nuance, which lies in the different structure of the software shell of devices, for example, restoring a deviation in instructions. This device does not give out data when dialing the *#06# command, so technically you will not be able to find out your ID number. But this problem is not so critical, since the number is written in a special instruction, which is provided along with the standard documentation, which it is desirable to keep. But if it was not possible to obtain this data, then you should pay attention to the possibility of manual

Manual recovery

Recovery IMEI Lenovo, Fly, Alcatel, Acer, Huawei, THL, Zopo, Explay and other devices based on the MTK processor has one nice feature that allows you to get rid of the error using manual editing. How is this possible? Everything is quite simple, the main thing is to know the basics of using the built-in menu of the device. Restoring IMEI through the engineering menu will require you to know special commands and menu features. But thanks to further instructions, you will be able to cope with these requirements and recover your identification number.

Recovery IMEI MTK begins with entering a command to call the internal menu. To do this, type the command *#*#3646633#*#* on the keyboard, which will allow you to call an additional function. In it, select the "Connectivity" item and the "CDS information" sub-item. After that, you need to go to "Radio Information", select "Phone" and after the inscription "AT +" enter "EGMR = 1.7,". Next, you should restart the device and use the command * # 06 # to get your IMEI data. It remains only to repeat the described procedure, but after the inscription "AT + EGMR = 1.7," enter your identifier data. This will get rid of the error, and you can continue to use your device. In the event that these methods did not help or you are not confident in your abilities, all that remains is to contact the service, where professional assistance will be provided to the device.

Service maintenance

The problem that concerns the identification number has been encountered by many users of various devices for a long time, so do not think that it is completely new and has no solution. Yes, there are not many opportunities to fix it personally, but almost any service can help. It is enough to bring the device to professionals, and it will be restored within a few hours or days. The device is best carried with special documentation, which has various technical data necessary to accurately determine the source of the problem, which may vary depending on the device model.

Model Features

Restoring IMEI is possible only when the processor of the device is determined. There are several varieties of these elements, which differ in their software shells. For example, the MTK processor has the largest line of devices mentioned above. But there are other processors - such giants as Samsung and Apple. Each of them has its own recovery methods, so it is worth remembering this nuance. All the methods that were presented in this article strictly apply to devices of the MTK family. Trying to use them for other devices is not recommended, as you can break the firmware, which will be difficult and expensive to restore. Therefore, you should be careful about the process of flashing and repairing IMEI, since any mistake can cause a breakdown. And errors can be very different, ranging from incorrectly entered data to the lack of necessary files.

Possible mistakes

Crashes, incorrect installation, data inconsistencies and much more... Errors can be very different and unpleasant. And, what is most interesting, all of them are the basis of the main problem - incorrect installation of the firmware on the device. And this already becomes the reason for the deactivation of IMEI and the failure of the device to work correctly. Therefore, if you are definitely not sure that you can personally flash your device, or do not have the appropriate skills, then it is better to postpone this idea and leave the work to those people who are well versed in this. But you can generally avoid this if you do not want to face these kinds of problems.

How to avoid the problem

To do this, you should understand that you have to use licensed products and in no case fall for the trick of hackers. The firmware is an element of developers, but users who do not want to use paid services prefer to personally find these files. Then they get to third-party sites and download firmware versions where the hackers have already made their changes, which later causes the device to break down. It is better if you use the products and programs that the developers themselves provide, and not third-party users. Moreover, the device is updated automatically if you are on the side of conscientious users. Therefore, do not put yourself and your device at risk. It is also worth noting that the developers are aware of the problem of “pirated” firmware, and they often release special files to fix problems, but, unfortunately, not all manufacturers do this.

Internet using

The IMEI recovery file can be obtained from the official website of the manufacturer to which your device belongs. If it is available, it must be downloaded and saved, because in the event of an IMEI-related problem, simply downloading the file to your device will correct the error and show you how to use the licensed product well. Be conscientious and you will never face unpleasant situations!

Reflashing a smartphone is a very serious matter. It is necessary to take into account the many features of a particular gadget model and, along the way, keep in mind the complete step-by-step instructions for the firmware. Otherwise, you can completely kill your device in seconds. For the most part, the process ends successfully. But there is a special category of smartphones (gadgets from the Celestial Empire based on MTK processors), which begin to "bewilder" after the firmware. And specifically - the IMEI of the phone flies. How to restore IMEI on "Android" after firmware? This will be discussed in our article.

What is IMEI?

IMEI is a special identification number that is assigned to the smartphone communication module. It is he who allows the device to "catch the network" and transmit data. Also, this serial number can be used to identify a stolen smartphone. When flashing using the appropriate hardware, you can change or "wipe" the IMEI, but you can not completely get rid of it. It is worth digging a little deeper - and it will manifest itself. Therefore, in no case should you purchase gadgets without documents or with a strange IMEI - they can be stolen.

Usually, when flashing a device, the IMEI remains in place, unless, of course, we have a smartphone from a well-known brand. For Chinese gadgets (especially on the MTK platform), the disappearance of the serial number of the communication module after flashing is a common thing. The good thing is that you can restore it (in most cases) without interfering with the firmware. The main thing is to have a recorded number in some documents. So, how to restore IMEI on Android after flashing? Let's take a look at specific examples.

Using the menu for engineers

This method does not work on all devices. But no one bothers to try. You need to enter the engineering menu using the command (typed on the keyboard) * # 3646633 # or * # * # 3646633 # * # *. Before that, do not forget to remove the SIM card from the smartphone. Next, go to the CDS item, then to RADIO INFORMATION - and select the PHONE 1 item there. After the inscription AT +, enter the line EGMR = 1.7, "". The quotation marks are used to enter the IMEI indicated on the sticker under the battery (for example, АТ+EGMR=1.7, "123456789123456"). Then you need to click on the SEND AT COMMAND tab. Process completed.

After completing all the operations, you should reboot the gadget and return the SIM card back. If mobile connection earned, then this method is suitable for your device. We answered the question of how to restore IMEI on Android after flashing without root rights. You don't really need to root your device to do this. However, this method is not suitable for everyone. For those for whom it did not work, the next part of the material will help. Let's go to her.

Tampering with firmware

If the first option did not help, then you will have to fix the firmware files. Here you will need superuser rights. You can get them through Framaroot or KingoRoot. The question of how to restore IMEI on Android after flashing through the engineering menu, it turns out, disappears by itself. To return the number of the communication module, you need to fix one file of the gadget's operating system. It is called MP0B_OO1 and is located here: /DATA/NVRAM/MD/NCRAM/NVD_IMEI.

Open the above directory (via Root Explorer) in some text editor and write the correct IMEI in it. Most likely, the file will be completely empty. So there shouldn't be any problems with that. This method works on all devices. We figured out how to restore IMEI on Android after flashing Lenovo or some other smartphone from China. Problems should not arise even for beginners.

Using Special Applications

There are some devices that do not allow you to delve into the firmware files or the engineering menu (especially smartphones from Samsung are guilty of this). How to restore IMEI on "Android" after flashing such a device? There is a way. It consists in using a special application. But for this you will need to get superuser rights. Then you need to download the Chamelephon program from Google Play and install it on the device.

Further, everything is very simple. The application will immediately display two windows in which the serial numbers. You can generate new ones or use existing ones. It will be enough to click on the Apply New IMEIs button. After successful completion of the operation, the application will ask you to restart the device. We do. After that, all networks should work. Now you know how to restore IMEI on Android after Samsung firmware or other devices of the same type.

Precautionary measures

Remember: no one will give you a guarantee that all the above methods will work adequately on your device. Therefore, experts recommend that before carrying out any work, do backup operating system of the device and all data. This is especially true for those who decide to use the method of editing system files. This method is very dangerous, as it can lead to fatal errors and complete inoperability of the device.

All other IMEI repair methods are mostly safe. But it still doesn't hurt to make a backup. Suddenly something goes wrong? Then nothing will interfere with returning a workable version of the OS and continuing to engage in scientific research.

Summary

The question of how to restore IMEI on Android after firmware (through the engineering menu too) has many answers. Not the fact that the above methods are right for you. But most of them help. The main thing is to do everything as described above, and, of course, make a backup copy. Then your device is safe. But don't forget to take precautions. We hope that everything will work out for you, and your gadget will live a long and happy life, delighting you with its speed. Just follow the instructions exactly - and everything will be fine!
