Slove Game Killer ROOT PRIVILAGE NEEDED Problem(with Screenshot & Video Tutorial) | TFA2

Hello friends...
Many of us are familiar to Game Killer. Basically It's an app for hacking any OFFLINE Game's Coins, scores, lifes etc... But there is a problem in Game Killer. When you launch this app its says "Root Privilege Needed" even if you are Rooted

So here is a short fix for this stupid message :-P
Let's get started. First of all you need a file explorer named ES File Explorer. You can download it from this link
Download ES File Explorer
Now install it and open it. Now swipe from left side or click 3 short lines on top left corner above

goto Tools and click on Root Explorer.

 It will ask you for Root Permission so ALLOW it.
Then goto Root by clicking the slash "/"  above.

Goto Data folder

then app

and find Game Killer. Then long press it and select MORE and go to properties

and click CHANGE button next to permission

and mark the boxes as below screenshot

Now change OWNER to ROOT

and GROUP to ROOT also.

All done, Now open the GAME KILLER and enjoy it.

Thanks :-)
