Is there any way to update firmware on a pro copter with the camera and gimbal broken? Currently it is at 1.5.3 kinda worried. No problems yet but still nervous. I have tried many times with sd cards in the cam base but it never gives the da da da da sounds. Led on base flashes red and green about 3 mins then flashing green about 3 mins then back to red and green. I have let it go for 1 hour no change and no txt files on the sd card.
