So I have some problems with modifying the google apps (Youtube, Gmail, Google+) because when I change the icon in the apk and I try to install it it gives me an error
"App not installed". I changed the icons with 7zip so I just dragged the modified icons to the right folder in the apk. When that didn't work out I decided to try APKmanager, but still no result because APKmanager is not working proparly
. I also have some problems with the Htc Music apk but I think that can be fixed by the htc-resources.apk .
