Today am going to give a tutorial on how you can backup your Mediatek Android Devices NVRAM To avoid Losing your IMEI after Factory Reset or Flashing a ROM.

Firstly lets know the Basic Info about NVRAM.

What Is NVRAM?
An Android devices IMEI is stored on a system file which is the Nvram, When a user performs an action that affects the system, The Nvram might get corrupt or even totally erased hereby causing the device to loss its IMEI and possess an invalid Imei.

The Nvram is a very important file because without this file your android system would not be able to register an Imei number if a system fault occurs.

The Nvram as earlier said is a system file that can not be modified expect if the user has root access on the device.
SInce you've known the Basics about the Nvram file, Now it`s time to know how to keep it safe to avoid loss of Imei Number.

  1. would be nice with a tutorial for people not running the windows virus, like people concerned about their safety and running linux or just people who don't have a pc. Asumming that everyone is running windows is mistake most writers make, I spent 29 years supporting Microsoft software until linux were ready to run stable on my system, not saying that linux is perfect for everyone, but it is allot more supported and stable than windows. I wish you writers would see that, so when you make a guide then you also make an alternative for other systems.

    1. This is a very nice point you have made here and i would surely put it into practice and perfect it with time.

      The fact is that majority of PC's run on the Windows OS, but just as you have said, an alternative should always be made for those not windows.
      Thank you for the tip.
