So....this mod themes the battery and signal bars and covert them to iOS 7 look.
It`s made for JB 4.3.
It`s a flashable zip, so copy it to internal or external memory and flash it via CWM or Philz Recovery.
Also if you don`t like this mod the script automatically makes a backup of the stock battery and signal, wich can be found in "data/media/UniversalFlasher/"
I hope you will enjoy it.
