mobile

Hello. Recently i have ran into a problem with Google Chrome, Now, and Play. I cant load those apps on Mobile Data. But i can load other apps just fine. I also ran into a problem with BBM. BBM keeps crashing even though i have reinstalled in thrice from GPlay on wifi. I want to try to Reset my phone. It runs on stock Android 4.4.2. I wonder if there is an app to backup all of data including App datas and Apps. I cant get it rooted. The phone is an Indonesian local brand, so i cant get the restoration ROMs if i want to try ADB rooting. Please help.
