VEX Cortex Lights blinking

Hi, doing some troubleshooting of the Cortex for the PLTW class where I live. Apparently the firmware has been updated but not sure.

So the issue is when they turn the Cortex on, the only thing that occurs is a blinking robot and game light for a brief bit, then it may turn red and still be blinking, or remain blinking green. Any clue what the issue could be?
