I am trying hide the default battery icon since I already have installed another battery indicator. Anyone know an easy way of doing this? Managed to find a way but needed to apply the zip file using this method -"Put the .zip of your choice into the root of your sdcard and apply via recovery. It will clear your dalvik cache automatically so it will take a little longer to reboot". Anyone can elaborate in detail how to apply the zip file?

Thanks in advance.
