I was trying out to change the color of the clock at lockscreen but when i rebooted the system, i found out that it could only go to the screen which requires me to enter password but the it automatically restarts again. When it reaches the screen which required the password, I quickly entered the password but i don't know why the phone restarts again by itself. It was auto-rebooting for 5 times. Can someone help me ASAP please! You help is much appreciated. Thank you.
