Apply the system theme and reboot. Now select my theme & apply.
You may get an error: 'Sorry, this theme is missing assets for your device's screen size'.
Ignore that and apply it anyway and REBOOT. CM9 CM10 CM10.2 CM11 & AOKP THEME
ROOT and a custom ROM like CyanogenMOD needed.
For HDPI,XHDPI and XXHDPI phones only.
This a minimalistic matte dark orange colored theme.
This theme has xxhdpi(1080p) assets and will look sharp on newer 1080p resolution phones such as Galaxy S4, HTC One, LG G2 and Nexus 5 etc.
The battery icon cannot be themed in Kitkat 4.4.
Use XPosedMOD along with GravityBOX to disable the icon altogether.
I have themed this battery app: https://play.google.com/store/apps/details?id=net.hubalek.android.gaugebattwidget
It will place a themed battery icon on your statusbar as seen in the screenshots.
