Problem after installing recovery.

So, I'm new in messing with android but I wanted to root my LG L9 p760 and give it some tweaks. I've rooted it and installed "busybox x" then added artas182x CWM recovery and reboot phone, after entering recovery and creating backup file on my external sd card I wanted to reboot but when phone is launching suddenly appears communicate "unfortunately, the process com.android.phone has stoppetd." and I'm left with white screen which has title: "Encrypting" and button to restart phone. Maybe someone had this problem and knows how to fix it? :(
