I just tried to change the icon for the contacts apk by replacing it inside the .apk itself and when i tried to put it back on my phone, the phone doesnt recognize the contacts apk anymore. I cant open my contacts or use the dialer because of it. I have the original Contacts.apk but even after replacing it back with the orginal, it still wont work. Someone please help me out. All i want is for my contacts to work again. I replaced it in the system/app folder also if that helps anyone out with coming up with a solution. Thanks. EDIT: I'm an idiot just figured it out. I had to fix the permissions. Feel free to delete this post to save me the embarassment lol.
