If the LEDs on your Gear are all lit up in a variety of colors (including green, blue, purple, and red) then fear not! You have simply entered Gear's self-test mode. This is used to diagnosis any possible issues inside the device.
To exit self-test mode, simply remove Gear's back lid to perform a hard reset. Be sure to put the back lid on again after as Gear will not turn on with the back lid removed!
