Not to be rude but try searching for your answers.. I picked up a KF last night for my fiancée it was rooted but restored to stock rom.. I tried getting it to allow prime videos and hosed it up big time. I I was getting fire logos loops all kinds of madness but I hopped on xda did some research now her kf is working with prime video and side installed apps and ADW Launcher as well as stock kf launcher..
