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

To make an IMEI backup, the first thing you need to do is charge your smartphone to at least 40%. Next, you need to install drivers for your device, as well as . Next in order:

For smartphones with MT67xx series processors, you additionally need to save NVDATA. Do everything the same as in the instructions above, starting from point 3.

Repairing IMEI after flashing using SP Flash Tool

1. In SP Flash Tool, specify your Scatter file and press " CTRL+ALT+V»
2. In the top menu of the program, mark the item Window – Write Memory
3. Switch to tab Write Memory
4. Fill in the item File Path by clicking on the folder icon and selecting your backup NVRAM
5. At point Region choose EMMC_USER(for MT6592 and above)
6. Open your Scatter in a text editor and copy linear_start_addr to line Begin Address (HEX)
7. Click Write Memory
8. Connect the switched off smartphone to the computer using a standard cable. The program will see the smartphone and write down the specified memory area, that is, it will eliminate the incorrect IMEI.

For MT67xx smartphones, you need to do the same for NVDATA.

After this, you need to flash the device with full factory firmware in accordance with the instructions for your smartphone. After flashing the firmware, you need to turn on the phone and reset it through the settings. Sometimes you need to flash the full firmware in Firmware Upgrade mode.

This IMEI firmware should always be stored on a computer or cloud service, the main thing is that you always have access to it, it is much easier than correcting an incorrect IMEI manually.

Restoring IMEI through the engineering menu

The main advantage of this method is that you do not need any root rights, nor any additional programs, everything is done directly on the phone. So, to change IMEI through the engineering menu, you will need the IMEI itself, which can be found on the smartphone box or under the phone cover.

How to change IMEI through the engineering menu:

1. Open your phone and enter *#*#3646633#*#* (the combination for your device may vary)
2. The engineering menu has opened, open the tab Connectivity
3. Go to CDC Information - Radio Information
4. This submenu has 2 items: Phone 1 And Phone 2, this is the first and second slot for SIM cards, open Phone 1
5. In the line where " AT+» enter the letter « E» in English and click on AT+EGMR=1.7,"IMEI" (instead of IMEI you need to enter your first IMEI) and press Send AT Command. After this, a message with the phrase Ok should appear, which means the IMEI is in place.
   

   IMPORTANT! After AT+ you need to put a space!

6. Do the same operations with Phone 2, only here you need to select AT+EGMR=1.10,"IMEI". Don't forget the space after AT+.
7. Reboot your smartphone and check the IMEI with the command *#06# .

Ready! You changed IMEI through the engineering menu. I strongly recommend that you enter the exact IMEI that was on the phone, otherwise there may be problems with mobile communications.

Repair IMEI with MAUI META

This method requires a PC. You will need a program MAUI META, installed drivers ( complete package And CDC driver) and a newly flashed phone via SP Flash Tools (preferably). You will also need the “BPLGUInfoCustomAppSrcP****” file from the installed firmware.

The main difficulty of restoring IMEI via MAUI META is to correctly connect the device in META Mode, one of the ways:

1. Install and run MAUI META
2. Click Reconnect, the indicator in the program will start flashing
3. Turn off your phone, press Volume Up and connect to PC
4. In Device Manager under " Ports» the device will appear MTK USB Port
5. Disconnect the device from the PC, disconnect and connect the battery, click Reconnect in the program and connect again with Volume Up, it will appear again MTK USB Port and the program will give an error, press Disconnect
6. Enable the option " Connect smartphone in META mode» and press Reconnect
7. Connect the device without pressing any buttons
8. The blinking indicator turns yellow, which means the smartphone is connected, you can restore IMEI!

The methods for entering META Mode are different for all devices!

If after a successful connection a program window pops up, close it, click Action - Open NVRAM database and select the file " BPLGUInfoCustomAppSrcP****"from the installed firmware. Following are the instructions:

1. From the drop down menu select IMEI download
2. The IMEI editing window appears, click Change NVRAM Database file and select the file from the firmware again
3. Enter the IMEI without the last digit in the IMEI field and press Download to Flash, do the same with the second IMEI if you have one
4. Close the window, click Disconnect and restart your smartphone
5. Check IMEI combination *#06#

General concepts about NVRAM on MTK
To store calibrations of wireless modules (GSM/Wi-Fi/BT/GPS) and equipment, identification information (IMEI, MAC), equipment settings (speaker, microphone, camera features) in the built-in flash (ROM) a separate fat-like memory area is provided called NVRAM. For the MT6516/MT6575 series processors, its size is 3MB. For the MT6577/89/72/82/92/95 series of processors, its size is 5MB.
When the phone first starts, information from this memory area is copied (cached) to the firmware /data/nvram. After which the data in the cache can be changed by the phone’s built-in software, as well as from the engineering menu. Resetting the phone to factory settings or flashing the userdata partition, either separately or as part of the firmware, erases this cache and upon first startup, the information from NVRAM is cached again (all user changes are lost and reset to factory settings).
Often, the Chinese themselves make the above mistakes during Russification and erase the NVRAM. Then they fix it with all sorts of programs like MobileUncleTools, ImeiRepair and the like. But all these fixes work until the first clearing of the /data partition (reset, full firmware via SP FlashTool or firmware via recovery if the firmware provides for clearing user data), because They do not correct the very reason for the “flying IMEI”, but are only a “CRUTCH”!!! What is fraught with the loss of IMEI is the inability of the phone to see networks, if it does, then the phone malfunctions and overheats, it quickly discharges, the radio, WI-FI, Bluetooth, etc. do not work.

Signs and methods for checking damaged NVRAM
A factory reset is done from the phone settings. Settings – Backup and reset – Reset settings. We control the IMEI status in Settings – About phone – Status (general information) – IMEI information. If IMEI is not there, then the nvram is damaged.

Instructions:
1.Install the program (you already have it)
2.In Options, click on Connect Smart Phone Into A Meta Mode
3. Turn off the body
4.Click in the Reconnect program
5.Open the device manager
6.Connect the switched off smartphone and catch the unknown device.
7.Put in drivers from the archive
8.In the program, select IMEI Download instead of Get Version
9.Click Change Nvram Database File and from the folder with the firmware select a file with a name starting with BPLGUI.
10. Enter the IMEI, but ATTENTION without the last digit (it will appear in the window next to it and will be exactly the same as yours if it is entered correctly).
11.Click Download to flash
