We will need following tools/files to this whole process:

Now first you have to install your MTK drivers. If you have already installed drivers to your PC then leave this step.
After driver installation download your scatter file, open that and Search for the word “NVRAM”.
Note down the values of “physical_start_addr:” and “partition_size:” (different devices have different values. For coolpad note 3; values are 0x380000 and 0x500000 respectively.
Now download Sp flash tool and open that. Select the scatter file and then click on Readback.
After that click on Add and then double click on created file.
Chose a folder to save this and name the file as nvram.img and click save.
