To install this file you will need to be rooted and running the Rogers 4.4.2 build.
I used TWRP to backup the two original files - /system/priv-app/SystemUI.apk and /system/priv-app/SystemUI.odex
I then copied the patched SystemUI.apk over the original and deleted the SystemUI.odex. Just to be safe ensure the permissions on the new SystemUI.apk are 0644.
Reboot and you're good to go.
I believe this only works with the Dalvik runtime.
You can get the patched file here:
You can see Ctrl-Freak's original AT&T mod instructions here:
100% of the credit for this goes to Ctrl-Freak !!!
I have created an updated version myself(never hurts to learn how to do this stuff) that has the battery percent meter enabled as well as the text inside the battery switched to a slightly larger font and changed to black.
