I just started doing vex this summer and have already messed up my microcontroller because i tried to update firmware without the controller hooked up. Now whenever i turn it on the game light is red and so is the vexnet light. I tried to update it and connect it to the computer many times to set it back to default but since the lights have been red the computer says its not connected. Please Help
Team 816,
Try manually setting the Cortex on download mode.
Details on this procedure are listed on page four of the attachment.
