Innovative developments are created with the best of intentions, but to avoid the occurrence various errors and failures are impossible. IN this review we'll talk about repairing IMEI. What is this function for at all? Today, users are more likely to encounter a device that stops working normally and at the same time an error appears that mentions IMEI. In this article, we will try to deal with this problem. The collected information will be useful to all users. We will also provide detailed instructions to restore the functionality of the device.
What is IMEI?
Before talking about restoring IMEI, you need to figure out what it is. The IMEI is the universal identification number of the device you are using. It is required for conditional registration and use various services. With this number you can receive technical support, install various applications and access the Internet. IMEI is the basis of device performance. But is it really so?
What is the main purpose of the identification measure? What is this function for? Hidden meaning This feature is that with the help of IMEI, operators can easily find out and collect all the information about your correspondence and calls, as well as about your favorite applications and preferences on the Internet. In other words, this is an electronic passport that allows you to find out almost everything about the user who uses this device. How can this be avoided? Many hackers have been able to do this, it just takes getting used to constantly changing data, formatting, and so on. For this reason, it is better not to rack your brains, but to use this function by appointment.
How to find the IMEI number?
This is done quite simply. Each user can check his identification number. All you need to do for this is to type the combination * # 06 # on the device's keyboard. The device will automatically issue a number, but only if it is activated. From that moment on, it will be possible to understand whether the device is working properly or broken. If there are no problems, you will be able to use all available options. If an error occurs, you may experience problems making calls. This implies that the device has identity issues that need to be fixed. What could cause such a situation? This will be discussed further.
Why can there be a problem with IMEI?
Suppose you decide to find out the identification number of your device, but the device did not issue this information. Have you also noticed that you cannot access the Internet, write text messages and make calls even though you have updated the firmware and reinstalled all applications. Here lies the problem that is the cause of this situation. During a firmware update, the software shell of the device changes. In this case, the codes are updated, erased unnecessary processes, a new structure is created.
In order not to spoil the device, it is better to entrust this procedure to professionals. But many users decide to flash the device themselves. Due to incorrect installation of program elements, failures may occur, leading to the loss of IMEI. It does not change, but simply loses its registration power.
This may cause failure of the main functions of the device. This issue is not critical. To restore the device to working capacity, you can use the services of specialized services. You can try doing this procedure independently, there are many ways that allow you to restore IMEI on devices running on Android based. Next, we will talk about what methods exist and how they can be used.
Ways to fix the error
If you encounter an IMEI error and find the main causes of this unpleasant situation, you can use one of the methods to solve this problem. You can try to restore IMEI via engineering menu or with the help of specialized programs. There are many ways. We will consider only the most effective and efficient. These methods allow you to access the internal settings of the system and further edit and change the structure.
These actions make it possible to amend and improve the performance of IMEI. Each method is unique in its own way. They have their own requirements, which must be met with special care. If you are not afraid to take risks and love innovation, you can try one of these methods. If you are not confident in your own abilities, then it is better to contact specialized service. Qualified specialists help you fix the error so you can use your device again. But keep in mind that this service costs money, so it’s better to immediately think about the appropriateness of using it.
Let's consider the simplest way to solve this problem. It consists in the use of special programs.
Using special programs
There are many applications on the Internet that can solve this problem automatically. Should we trust these promises? To use this procedure, you can use one of the specialized applications. You can use GScriptLite apk to repair IMEI. This regular application, which makes it possible to authorize an identification number using an operator request. You need to download and install the application.
After that, run the program and add a script called "needs su". It has standard IMEI number indicators. After you add this script, you will need to change its data, while registering your IMEI. The procedure for establishing the identification number has already been described above. It remains only to save the changes and activate the script. To perform this operation, you must have superuser rights. You can approve the action by clicking "OK".
After that, you will only need to restart the device. There is a small feature, which consists in the different structure of the software shell for devices from different manufacturers. So, for example, when restoring IMEI in devices from Samsung there is some deviation from the instructions above. Devices from this manufacturer do not output data when using the *#06# command. Technically, you won't be able to find out the device's ID number. This problem is not critical, since the identification number is written in a special instruction, so it is desirable to keep it. If you cannot get this information, you must use the manual method to fix the problem.
Manual recovery
In devices from Fly, Huawei, Lenovo, High Scree, Acer, THL, Explay, Zopo, as well as devices based on the MTK processor, there is one feature that makes it possible to fix the error by manual editing. Is it possible? Manual editing is quite simple, you just need to know the basics of using the device's built-in menu. To restore IMEI through the engineering menu, the user will have to know the special commands and subtleties of working with the menu. Using the instructions below, you will be able to independently cope with this procedure and restore the IMEI of the device.
To restore IMEI on devices with an MTK processor, first of all, you need to enter a command to call the internal menu. You need to call additional function using the command *#*#3646633#*#*. Here you need to select the “Connectivity” item, and then go to the “CDS Information” item. Here you need to select "Radio Information" and "Phone". After the inscription "AT +" enter "EGMR = 1.7". Now you can reboot your device and use the *#06# command to find out the identification number of your device. These steps will eliminate the error and use the device further. If the methods described above did not help, there is only one way to fix the problem: contact a specialized service. There, your device will be provided with professional assistance.
Specialized Services
Many users have already encountered problems related to the device identification number. This problem is not new, and there are many ways to solve it. Not all users can fix this problem on their own. But in the service specialists will always be able to correct the situation. All you need to do is take the device to the professionals. After a few days, or even hours, the performance of the device will be restored. Together with the device, it is better to take the documentation to the service, which describes technical information that may be useful to determine the cause of the problem. The causes of this problem may vary depending on the device model.
Features of IMEI recovery on various models
To restore the IMEI number, you must determine the processor of the device. There are several varieties of these elements with different software shells. Many devices use the MTK processor. However, there are other processors that giants such as Apple and Samsung use in their devices.
Each device has its own recovery method. It is worth considering these features. All the methods that have been discussed in this article apply to devices with an MTK processor. It is not recommended to use them for other devices. This can break the firmware, and its restoration will cost the user dearly. For this reason, you need to be very careful in the process of recovering an identification number. Any mistake can lead to damage. This may be incorrectly entered data, or a lack of necessary files.
Possible mistakes
Inconsistency of input data, system failures, incorrect installation... These and other errors can occur when working with the device. All of them can lead to incorrect installation of the firmware, and this, in turn, leads to IMEI deactivation and problems with the device. If you are not confident in your own abilities, it is better to leave this work to professionals. The occurrence of such problems can be generally avoided if you do not encounter situations of this kind in the future.
How to avoid the problem?
To avoid problems associated with repairing IMEI, you must use only licensed products and not fall for the tricks of hackers. Firmware is an element provided by the developers. Many users who do not want to use paid services prefer to search on their own necessary files. After that, they download firmware versions from third-party sites. Attackers could make changes to them, for this reason, installing such firmware quite often leads to device failure.
It is still better to use software provided by developers rather than third-party users. The device is updated in automatic mode. Do not use "pirated" firmware and put your device at risk. Developers are well aware of this problem, so they often release special files to fix these problems. But not all manufacturers do this.
Using the Internet
A special IMEI recovery file can be obtained from the official website of your device manufacturer. If you find such a file, you will need to download it and save it to your device. If there is a problem with the IMEI, you can simply download the file to your device. He will correct the error and prove that it is always better to use licensed products. Remember: conscientious users rarely encounter unpleasant situations.
Wrong IMEI - system message that occurs after reinstallation operating system on android. IMEI is a unique 15 or 17 digit phone code that is its identifier. The serial number gives information about the location of the device. When lost or stolen, it is used to lock and locate the device.
Also, if an error occurs, it becomes impossible to use cellular communication Whether it's a smartphone or tablet. The first sign that the name has been changed or deleted is that the device does not make calls or access the Internet, even if it shows the network and operator.
If the imei is deleted or incorrect, it may be a return to the factory settings. It can also happen as a result of incorrect loading new firmware, as well as in the software. Third party software for Android may adversely affect the device.
You can easily find out IMEI by dialing the combination * # 06 # in the call, the number is automatically displayed without pressing the call button. The second way is to inspect the phone under the battery, or find it on the warranty card or packaging. If the phone has two SIM cards, both codes are indicated inside.
How to Repair Wrong IMEI After Android Flash
To restore IMEI yourself, you need to be sure that the actions taken are correct. If any of the instructions did not help, contact the service center.
Before you fix invalid IMEI you need to make sure that the settings are incorrect - compare the combinations on the device and documents. If the problem appeared after the firmware, you must perform manual configuration:
- Remove the SIM card (if there are two, both).
- Find the code on the Internet to enter " engineering mode» for your phone model. For example, for Lenovo A319, the code looks like "*#*#3646633#*#*" .
- Wait for a while, do not execute any commands on the phone.
- A menu will open in which you must select the "connections" item.
- Select "CDS details".
- The menu will open on English language, where you need to select the item "radio information".
- Select Phone1 if there is only one SIM card in the phone.
- A window will open asking you to enter the letter E.

- Select "send at command", after which an error message may appear.
- In case of an error, add a space after the + on the same line where the IMEI was entered.
- Reboot your phone.
The smartphone given as an example has two SIM cards. After setting the settings on Phone1 (point 6), you need to repeat the operations for Phone2 and only then restart the phone. The considered method is similar for all Android devices.
If the problem is not solved, then the problem is in other settings:
- Go to the engineering menu;
- Select Telephony, then GPRS;
- Select SIM1 and enter the correct IMEI manually;
- Repeat if you have a second SIM card by selecting SIM2;
- Restart your device;
- Check if the settings have changed via the USSD command.
When restoring IMEI through engineering settings, you cannot change others, this can cause other damage to the system.
If these methods do not fit, changing the name will help:
- Download the 360root app;
- Run the program and click on the button for obtaining root rights;
- Download on Google play app to change the name (for example, Chamelephone);
- Launch the application and follow the instructions;
- Reboot after setting.
In addition to the above method, there are many others. You may need to manually change the IMEI so that the device is not found.
What can be done using IMEI if the device has been lost?
You can track your lost phone using your Google account - go to Personal Area. If the smartphone has been linked to this account, the "Android" function will be available. It displays information about the device, recent activities. If for some reason the account was unlinked or not linked at all, the function will not be available.
If your phone is stolen, you must contact law enforcement. If you have them and with the help of your carrier, they have access to information about the location of the device. Such an operation can only be carried out with special equipment.

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 basic identifiers - your SIM card number and the phone's 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 of the Android operating system, which gives the user full control over the device, IMEI has ceased to be a stigma and has become a parameter that can be very easily changed or lost in an unfortunate set of 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 that the IMEI specified in the phone does not match 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 zero (000000000000000), repair IMEI- this is a change of 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 enter the 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:
| Manufacturer | Service code |
| MTK processor | *#*#3646633#*#*, *#*#54298#*#* |
| Samsung | *#*#8255#*#*, *#*#4636#*#* |
| HTC | *#*#8255#*#*, *#*#4636#*#*, *#*#3424#*#* |
| Sony | *#*#7378423#*#* |
| iPhone 5 on Android | *#*#4634#*#* |
| Philips, Fly, Alcatel | *#*#3646633#*#* |
| Huawei | *#*#2846579#*#* |
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 the 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.
- If you have not previously installed applications from external sources, go to android settings and open the "Security" tab in the "Personal Data" section.
- Activate the "Unknown Sources" option.
- Download from the Internet latest version Framaroot. This application has analogues in the Play Market, but they may not be as reliable.
- Install Framaroot. If the installer blocks the process, select " Additional Information” and click “Install anyway (unsafe)”.
- Launch Framaroot and select "Install SuperSU", then click on any of the methods for obtaining root rights. Once received, reboot your device.
- There is a possibility that your device is not supported by this application. 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.
