Default [AT&T HTC ONE X] v4 ICS Theme Apk

I read the info in the thread pertaining to this rom, and the OP of the thread said to place a folder called "Themes" into the data/system directory to fix the theme manager bug. Thing is, i dont even know where that is.

I found Android>data but theres no system inside of the data folder.
Just wondering if anybody can give me anymore specific directions to the directory to place the folder in to fix the Theme apk. Its probably really simple i just dont know where to look.

the original thread is here:
