(Help) Regarding Changing Custom Battery Icon

[samnettt]

Hi Guys.

My Device is i8190 - Stock Rooted
Android Version 4.1.2
Baseband : XXAMG4

I tried with Gravity Box,Rom Tool Box to change my Stock Battery style to Circle with percentage text.
But, unfortunately i couldn't. Meanwhile, i changed the colour and style of network signal,data signal and alarm icon,etc .but, nothing with battery

What's the problem Guys.?

Thank you.
