Goto settings-storage

You can clearly notice

The size of internal storage is around 4gb.

Thats why we need to backup internal storage as its get formatted in process.

If you browse apps you can see there is already super user app

It means it is prerooted.

6. Further Trouble shooting in kitkat

If at all superuser not working use root genius to root your phone.

Next most imp thing is sd card permissions.

its disabled in kitkat by defalut.

so u just use this app or manually put platform.xml in system/etc/permission ( u will get this anywhere just google)

another alternatives

1. KitKat SD Card Full Access.

2. HandleExternalStorage.

NOW ENJOY KITKAT FULLY.​

If you have any query or doubts regarding whole procedure please feel free to pm.

Yes this process involves risk of bricking your phone, but thanks to mediatek as there chipsets are bootloader unlocked and we can revert back from any worst possible conditions.:)
