Looks like you package (4.2.2) was corrupted (maybe bad download) or your recovery wasn't compatible (most likely). When you mess things up like this, first calm down and clear your data/cache, and flash your rom again. If that doesn't work, go to stock via odin and go ahead from there. Also, don't forget to make a nandroid backup next time and read instructions carefully and calmly.
