yep.. the values folder is only visible in a decompile. id leave 7zip out of this. just go into drawable and go to progress_horizontl and edit it with noepad, notepad++ or whatever you use. save it. WHen recompiling (if you are using apk manager 4.9) go into the keep folder and delete resources.arsc and any xml you edited and then let it finish. don't sign it. just change the unsignedframework-res.apk name to framework-res.apk
lol... the only way you could have deleted styles is if you did it before you started the recompile. dont delete that. when you delete, resources.arsc, you are essentially deleting the values folder. Only delete things in the keep folder. never from anywhere else. So basically, you can delete resources.arsc, and then any xml you edited in the drawables folder and the layout folder. possibly the xml folder.
