dang it! the SD card says SUCCESS!! I was waiting for the green lights. I guess the sound change is the important thing. the cam led was green; also, I didn't know to look there.
thnaks guys
If anyone else needs help with the firmware update, then see the link below. It contains detailed instructions that explain exactly which lights to watch, etc.
It does seem it can take longer than some earlier ones though, I'd allow a good 30 minutes.
There is a worrying long pause when it looks almost dead which lasts several minutes.
read the firmware upgrade instructios, need look at the gimbal LED light in front not the LED under the motor arm, it blink green and red when it in process and solid green when finish, mine took about 15min.
