To use the camera in team mode the ST-16 needs to be bound to a second device. Team means more than one and if all you have is the ST-16 with nothing else to link/bind to it will revert to single mode.
On a side note, if performing a system upgrade and the system does not recognize the camera/autopilot upgrade, put the ST-16 switch in the team mode and go back to system settings to refresh the firmware. Team mode puts the -16 in a "search" mode where it is "looking" for something, which seems to make it easier for it to locate "flightmode" firmware. When the firmware upgrade is complete you'll find the -16 has gone back into single mode.
I'm getting camera response error! Decompress processing timeout! When I am trying to do the update. The camera LED is flashing green twice one purple and then repeats again. I can't get video to the controller.
Any help would be deeply appreciated.
Sounds to me like you need to re-install the update and start all over with the binding and calibrations ... watch the attached video and follow it closely ... but instead of updating OTA use the old method using micro sdhc cards ... make sure you wipe the card before using to make sure there is nothing on it before you use ... most people are using the card that came with your H.
Good Luck ... I'm sure it will come together and you'll be back flying soon.
