Hi mates my 4th POst on XDA

MODS and TWEAKS for Karbonn a21 and a9+

Download Root Explorer OR Root Browser

Goto System u'll see Build.pro long press on it a pop up ill open click open Text editor

Copy this To Bottom OF ur Build.pro

Don't report any Bugs

This Build pro disables Boot animation and shutdown animation

Try at ur own risk

Important Note : Before u begin make sure u have backup
