Hello all. I have a droid razr maxx that is rooted and when i was messing around with stuff i seem to have messed up something with my texting app and it was gone. I found the app .apk in my system/app folder but when attempting to install it i got a "app not installed". Frustrated with it i decided to just factory restore and just start everything fresh. Did a factory restore and my texting app is still not there and i still cant install it. I need help.
