How to Backup MTK Android Stock ROM
Backing up any MTK android stock ROM would not have been possible if not with the help of the MTK Droid Tools.MTK Droid Tools is a Windows program released by one of the XDA developers recently. The MTK Droid Tools has proven so useful recently.
As a matter of fact, I have used the MTK Droid Tools to backup several stock ROMs of MTK android devices and used the backups to revive some dead MTK android devices which include Tecno Q1, Tecno M7, F7, some infinix and iTel phones.
