shooTing
If your EV3 Brick suddenly stops working and cannot be shut down
through the normal process, you will need to reset your EV3 Brick.
Resetting the EV3 Brick does not delete existing files and projects
from previous sessions in the EV3 Brick memory. Files and projects
from the existing session will be lost.
 Make sure that the EV3 Brick is turned on.
 Hold down the Back, Center, and Left buttons on the EV3 Brick.
 When the screen goes blank, release the Back button.
 When the screen says “Starting,” release the Center and Left
buttons.
