I successfully flashed the 4.5.5 FW on the SpeedyBee F405 V4 flight controller.
I completed the radio calibration and GPS/Gyro calibration, and everything was working fine. However, as I plugged the battery to verify the motor direction, I lost the COM Port.
Subsequent attempts are failing to open COM port. The red led is solid RED, and a white LED close to the gyro chip is solid white.
Any suggestions, did I brick it?
