How to Fix Null IMEI by Restoring nvram & nvdata in SP Flash Tool

In this guide, we will show you the steps to fix the null IMEI by restoring the NVRAM and NVDATA in the SP Flash Tool. Right after you unlock the device’s bootloader and before you flash any custom binary or root your device, the first step is to take a backup of some of your device’s important partitions, among which the IMEI number would occupy the topmost position in the pecking order.

While some devices have it in the EFS partition, others have it in the devinfo, both of which can easily be recovered just by flashing the file via Fastboot Commands. However, that isn’t the case with MediaTek devices, whose IMEI number is stored in the NVRAM and NVDATA. To recover the data from these partitions, you’ll have to take the help of a dedicated tool. And in this guide, we will show you how to do just that. So without further ado, let’s get started.
