[Q] Is there a way to change the design of Soft Keys for TW Based JB?

Hi!

Would like to ask if there is a way to change the design of Soft Keys for TW Based ROM? I did this step http://forum.xda-developers.com/show...hlight=softkey to activate soft keys but how to change the design? I have a little knowledge on unpacking apk and repacking it. Is there a specific file that I need to be able to change its design?

I tried SoftKeys http://forum.xda-developers.com/show....php?t=1413582 but won't work. Guess its for AOPK and CM based only.

Would really appreciate your help! Thanks!
