Lenovo NVRAM Backup Collection!


Lenovo NVRAM Backup

Collection










< What is NVRAM? >

Quote:
Non-Volatile Random Access Memory, a type of memory that retains it’s contests after switching off a device. It consist of SRAM and EEPROM chips. NVRAM contains data like WiFi and Bluetooth MAC address, Baseband version, IMEI/MEID number and other essential information.

So losing or corrupt NVRAM data means you will not be able to use your device with any mobile network or connect to WiFi.
< How to Backup NVRAM? >



< Method #1 >

Quote:
  • Download MTKdroid Tools.
  • Unzip the file on your PC and run MTKdroidTools.exe.
  • Enable USB Debugging in your Android phone by going to “Settings> About Phone” and locate “Build Number“. Then tap on build number seven time and now you have “Developer Options” enabled in your device. Go back to “Settings” page and tap on “Developer Options“. Now tap on “USB Debugging” check box to enable USB debugging in your device.
  • Connect your device to your PC via USB cable.
  • Click on the “Root” button at the bottom of the program window and grant root permission in your phone.
  • Now click on “IMEI/NVRAM” button. A pop-up window will be appeared.
  • Click on “Backup” button and the application will backup your IMEI/NVRAM data in the “BackupNVRAM” folder inside “MTKdroidTools” folder.
< Method #2 >



Quote:
taskkill /f /im adb.exe

adb.exe shell su -c "dd if=/dev/nvram of=/data/local/tmp/nvram.img bs=5242880c count=1"

adb shell su -c "chmod 0777 /data/local/tmp/nvram.img"

adb.exe pull /data/local/tmp/nvram.img nvram.img

K910L is an Qualcomm based device, This thread for MTK based devices only,
Although, What you need is an (QCN) backup for your phone, I've been searching around for a one, But couldn't find any.
