[HELP] Blank screen factory reset Only status bar on screen.

This happened after using Odin.screen is just black apart from the wifi and battery sign. I was trying to remove CM.

So after i used odin phone rebooted like a fresh install but when the phone booted up the wifi password was already in meaning it maybe is still on CM?
