alright im sure this has been answered but i cant find it. Im really new at this, just rooted for my first time 2 days ago.. anyways Im using root browser to rename, copy, and change permissions. when i move the homescreen.apk to system/app and change the permission, it only gives me the choice to uninstall not install. so far i got the gallery, camera, and messaging to work. every time i try to install the circles app i get a parse error. i have tried moving it to system/app and changed permission and no luck.
