Backup Unrooted Stock ROM on Mediatek Devices

Most phone users now use Android devices because it
has friendly interface and it is tecky.
The manufacturers of Android operating system are 
 releasing devices with much greater 
specifications and compactness. Even in the recent months, 
we have seen a lot of Octa core and Hexa core devices, 
we also witnessed devices with processing power which 
can put a low-end and mid-end laptops to shame. 
But manufacturers always try to restrict users from accessing 
the full power of the device to make sure the device’s life time 
gets a boost.

But the true power of the device can only be enjoyed once the 
user is in full control of the device, not the manufacturer. So many
developers and hackers developed scripts and tools that can exploit 
the Android devices and give full permissions to the user, 
which is a popular process known as Rooting. Once user gets
 full access, he can play with the entire power of the device but 
this may damage the device.
So we need to make sure to take a backup of the device in case 
we run into situations where we cannot boot the device or some other issues.

Mediatek chipset is the most common chipset that is available in the
budget devices to cut the costs. Taking a backup is easy once we have 
a custom recovery, but if the device is unrooted the process is not a 
straight road. However, by following this detailed guide you can take a 
backup of your mediatek powered device using this simple process.

WARNING!

Warranty may be void of your device if you follow the 

procedures given on this page.

You only are responsible for your device. We won’t be

Before you begin with guide instructions below, make sure 

your android device is adequately charged — at least 50% 

battery of the device.

STEP 1: CHECK THE CHIPSET

To make sure that this process works perfectly for you, 

ensure that your device is powered by a mediatek chipset. 

Usually all mediatek chipsets are represented as MTXXXX 

where the XXXX denotes the model number of the chipset.

STEP 2: BACKUP YOUR DEVICE

Back up important data and stuff before you start playing 

around here as there are chances you might lose your apps 

and app-data (app settings, game progress, etc.), and in rare

case, files on the internal memory, too.

You must have proper and working driver installed on your windows computer to be able to successfully backup firmwares on your device.
