CM9, CM10, CM11, AOKP, BAMF THEME
PLEASE READ THE INSTRUCTIONS BEFORE LEAVING REVIEWS.
THIS THEME IS FOR HDPI AND XHDPI PHONES ONLY.
ROOT needed and a custom ROM like CM9/AOKP needed that supports the Theme Engine.
Download the theme, go to settings/themes and 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.
The lock screen and some system dialogs cannot be themed in the T-Mobile Theme Engine, therefore they will remain unchanged.
If you get an Error Message stating that the theme was "Improperly Compiled..." just apply the "system" theme, and reboot your phone. Once your device boots back up go back into the Theme Chooser and apply Crimson Cobalt.
Crimson Cobalt is a Red & Black theme that is vastly different than stock ICS
