For the cha cha no it will work for sensation, check to see if xda has a cha cha site as I'm only familiar with sensation. Perhaps they have a chacha forum? I'm not sure. You can search and see.but this is the solution for the sensation only don't try it with your device. It can harm it. See if their is a forum for your particular device. Hope this helps.
