I was using Night Owl Beta 4 on my n7000 yesterday.. today morning when i woke up.. The screen wasnt responding to the power button so i rebooted the phone by pressing the power button for 5secs.. the phone got stuck on the samsung screen which comes in the starting.. then i tried to wipe data/factory reset through recovery because i hadnt taken a backup..so that got stuck too. so i decided to flash the stock rom via odin but no that is getting stuck too! please help!!! :crying:
