Those who use smartphones based on Chinese MediaTek processors know very well what an incorrect IMEI is. What to do if IMEI on Android is lost? Most often this happens after flashing the firmware or general reset of the smartphone. Don't worry, most of these errors can be corrected.

Restoring IMEI on Android will not take much time if you backup NVRAM and NVDATA from your device in advance.

Where is IMEI stored on Android?

To make a backup of IMEI you need to know where it is stored. On devices with MediaTek processors (90% of Chinese smartphones and 50% of budget devices from well-known manufacturers), the IMEI is stored in NVRAM. In addition to IMEI, it stores data about the calibration of wireless modules, identification information (IMEI, MAC), as well as settings for some equipment.

The device’s firmware provides a separate memory area called NVRAM; during the first startup of the smartphone, information from there is copied to the directory /data/nvram. After this, the data in this directory may change for various reasons, including problems with the firmware.

How can NVRAM be damaged?

• Formatting a smartphone using SP Flash Tool
• Using the wrong version of SP Flash Tool
• Memory re-partitioning
• Partial firmware
• Interrupted smartphone firmware process

Signs of damaged NVRAM, or how to find out that IMEI has been lost

• When entering *#06# Empty fields appear in the dialer for IMEI 1 and IMEI 2
• When Wi-Fi is turned on, a virtual network appears " Nvram warning err = 0x10»

Backup IMEI on Android using SP Flash Tool

Recheck the entered data and press Read Back

Turn off the smartphone, remove and reinsert the battery, if this is not possible, then wait 1 minute after turning off. Connect the switched off smartphone to the PC with a working cable, the program will pick up the smartphone and after a few seconds a small window with a green checkmark will appear, which means everything is correct.

Disconnect your smartphone from your PC and check the saved file along the path you specified in step 3.

More clearly in the video.

There are often situations when, for example, after updating the firmware and then installing all applications, you cannot access the Internet, make calls or write SMS. The fact is that along with a change in firmware, the software shell of the device is changed, codes are updated, unwanted processes are removed, and a new structure is created.

But you need to understand that any mistake made during the installation of any program elements can cause a violation in the system, leading to the loss of IMEI - a special number stored in the device’s firmware and identifying it on the network. You can see it on the packaging (box), in the instructions included with the smartphone (warranty card), under the battery of the device itself.

If your device is designed for two SIM cards, then two IMEI will be indicated.

On a normally functioning phone, finding out the identification number is not difficult at all - in the telephone number entry field you need to type the following combination of characters: *#06# (on some devices you also press the call button), then the corresponding information should appear on the screen. If your request was unsuccessful, then the same failure as mentioned above has occurred.

But, not everything is so hopeless - the identification number has not changed and has not gone anywhere, but simply lost its own registration power, and this is the reason for the failure of the main functions of your device. We will now tell you what can be done in this situation.

There are several ways to restore the functionality of your Android device.

The first, and most reliable, is to trust the services of a specialized service; you just need to find out its location. But we are not used to looking for easy ways!

Those who love experiments and those who are confident in themselves can immediately move on to the second method.

Before using this method, you should know that you need “Superuser” (or) rights. Now, you need to write down the IMEI of your device (see paragraph above), then step by step:

Download and install the program.

We open the utility, give permission to the request and find the “data” folder, go into it, then find the “nvram” folder, then “md.”, where the “NVRAM” folder is located, which we delete and wait until our Android recreates the files , after which a window should appear in which the operator of the network used will be determined.

We go to the engineering menu by typing the following combination of characters in the number entry field: *2366*#

We are looking for CDS Information, then - Radio Information, and - Phone 1.

In the line after the letters AT+ we enter E, it should turn out: AT+EGMR=1.7,"" and also AT+EGMR=1.10,""
Now, having selected AT+EGMR=1.7,"" in quotation marks, enter your identification number of the first SIM card (it turns out AT+EGMR=1.7,"967311665444199″), after that, under the line click SEND AT COMMAND, below should appear entry "AT command is mSent".

After prolonged use, any smartphone may begin to work incorrectly and produce errors. Both global brands (HTC, Samsung, Lenovo, etc.) and Chinese counterfeits are susceptible to this. In extreme cases, it is necessary to flash the system, reset the device to factory settings, after which the IMEI may be lost, which should be restored.

What to do if after the firmware the phone does not see the network

Users do not always turn to the service center for help. Changing the firmware is not a simple process, after which problems with the device may arise, so a successful installation is very important for the performance of the smartphone. One of the possible consequences due to an error during the procedure is that the phone does not see the network. If this happens, you need to check if you have a code in your phone. If it is missing, then below are ways to restore IMEI on Android after flashing it.

How to restore memory on Android yourself

The absence of an imey code on Android leads to the loss of the smartphone’s communication signal. Your gadget turns into a useless device that can neither send SMS nor make calls. After unsuccessful firmware, it is better to take the device to a specialist, but if you wish, you can try to restore the code yourself. In some cases, re-installing a new version of the OS helps. There are several options for how to register IM on your Android phone:

• using specialized programs;
• manual recovery via the engineering menu.

Manual recovery on Android

To make sure there is no imey code, dial *#606#. If nothing appears on the screen, it’s time to start restoring. You can find the identification number inside the phone itself (usually written under the battery) or on the device box.
