Then maybe they can fix it.<BR /><BR />You could also go into recovery by turning the phone off then press volume up and power at the same time and hold until the splash screen then just keep holding volume up until you are in recovery menu. Use volume to select clear cache. Then clear the cache. Restart the phone and try the theme again. First go to normal theme then reapply your custom theme.
