A student brought me their V5 controller and the screen is lit up with the word VEX showing. That is all it will do. Even when charging, this is all it shows. What can I do to fix this? Holding the power button does not do the trick.
When it is tethered to the Brain via a smart cable, does it need a firmware update?
There is also a reset button recessed into the back of the controller. You could try pressing this when powered on with a screwdriver or something else long enough to reach it.
Thank you!! The hidden reset button did the trick.
