Download from here NVRAM Backups for some Itel Android devices. These NVRAM files can be sued when it comes to fixing IMEI issues and consequentially network problems on your Itel Android device.

In some cases, when your device NVRAM that stores information like the IMEI number gets corrupted, your device will display a nulled IMEI and or an Unknown baseband error message. When this arises, your Android device won't be able to receive any network signals.

Fixing this can be done via flashing the entire stock firmware, but an easier way will be restoring the NVRAM to fic the issue.

The IMEI means International Mobile Station Equipment Identity and it stores 15 decimal digits (14 digits plus a clock digit). 

These digits contain the unique identification number for GSM, UMTS, LTE devices so without this data you cannot use your Android device at all. On the other hand, NVRAM (Non-Volatile Random Access Memory) represents a certain memory that retains its contests after switching off a device. It consists of SRAM and EEPROM chips. NVRAM contains data like WiFi and Bluetooth MAC address, Baseband version, IMEI/MEID number and other essential information.

Backing up the NVRAM partition of your Android device

You can backup and restore the NVRAM partition of your MTK or PSD based Itel Android pretty easily. To do this, you will need to have the MKT or SPD drivers installed on your computer, and also have the appropriate tool.

You can use Sp flash tool for backing up the NVRAM of your Android, Miracle CM2, Miracle Box or even the PSD Research tool. Each of these tools will create an NVRAM backup in a different format.

An easy to use tool for this is the Miracle Box. Miracle Box (including the thunder edition) will create and NV backup in the .bin format. 

Whereas using SP flash tool for example you will get a scatter.txt file containing the nvram.bin & nvdata.img.

Restoring your NVRAM file

By default, these files are not usually activated for flashing. So, you will have to edit the scatter.txt file to flash the nvram.bin and nvdata.img 

- partition_index: SYS3
  partition_name: nvram
  file_name: nvram.bin
  is_download: false → Change this to true
  type: NORMAL_ROM
  linear_start_addr: 0x380000        
  physical_start_addr: 0x380000        
  partition_size: 0x500000        
  region: EMMC_USER
  storage: HW_STORAGE_EMMC
  boundary_check: true
  is_reserved: false
  operation_type: BINREGION
  reserve: 0x00

- partition_index: SYS20
  partition_name: nvdata
  file_name: nvdata.img
  is_download: false → Change this to true
  type: EXT4_IMG
  linear_start_addr: 0x1af00000      
  physical_start_addr: 0x1af00000      
  partition_size: 0x2000000      
  region: EMMC_USER
  storage: HW_STORAGE_EMMC
  boundary_check: true
  is_reserved: false
  operation_type: INVISIBLE
  reserve: 0x00

Once you edit the is_download statements to true, you can load your scatter file from the folder containing the nvram.bin and nvdata.img file and flash using SP flash tools.

With Miracle box, it is even easier. Your backup NV file will be one single bin file and you can restore easily.

This what you'll have to do;

• Make sure you have drivers installed.
• Launch Miracle Box and check the 'write NV' option. Also, check "Android", load your device NVRAM file and click the start button.
• Power off your device and connect to the computer via USB; Wait for the flashing to complete.
