Have an 81c with succession 3.0. A few of the last 3904's installed come up with a version 8.3. but most are 8.7. I understand that flash updates to the 3904 is not automatic when the set is installed. I only use OTM for updates etc. There is an option in OTM to do a "normal" flash download to the set. Does anyone know what this means? There is also a "force download" which I know happens immediately.
