First you must know the syntax and what parameters to use.

Here’s a sample syntax to help you start the process :
shutdown [-s] [-f] [-m [ComputerName]] [-t xx] [-c “message”] [-d[u][p]:xx:yy]

And here are the parameters that you can use:

-l : Logs off the current name, this is also the defualt. -m ComputerName takes precedence.
-s : Shuts down the local computer.
-r : Reboots after shutdown.
-a : Aborts shutdown. Ignores other parameters, except -l and ComputerName. You can only use -a during the time-out period.
-f : Forces running applications to close.
-m [ComputerName] : Specifies the computer that you want to shut down.
-t xx : Sets the timer for system shutdown in xx seconds. The default is 20 seconds.
-c “message” : Specifies a message to be displayed in the Message area of the System Shutdown window. You can use a maximum of 127 characters. You must enclose the message in quotation marks.
-d [u][p]:xx:yy : Lists the reason code for the shutdown. The following table lists the different values.

Here’s a complete guide and infos about the process :



This means that your OS on your device has crashed itself meaning that the only possible option that you will have is to perform a hard reset on the device. This problem is linked mostly to people who have rooted their devices.

In order to get past this screen (if your device is not badly damaged) will be to perform the steps below in order to have your device back up and running correctly.

On the screen press these button:

-Press the volume button down
-This will take you to the recovery screen
-On the screen use the volume keys to highlight the factory reset option
-Press your power button to make the selection
-Your device will erase all name data (also root data)
-From here you are going to need to use the volume keys to highlight the reboot device option
-Press the power button to make the selection on your device

Your device will now reboot itself back to its factory settings

If the volume key in the beginning does not work then power off the device and start the process by holding Power + volume up + volume down key until you reach the boot menu.
