***** Anthem has now posted "Official" firmware V3.10 for the D2v/3D and AVM 50v/3D *****
Anthem has just updated their web site in conjunction with the release of the new, Generation 2 MRX Receivers.
As part of that, they updated the public downloads page (linked above).
Firmware v3.10 is now shown as the public, Official firmware for *ONLY* the 3D equipped version pre-pros -- i.e., the D2v/3D and the AVM 50v/3D
Firmware v3.09 is still shown as the Official firmware for the *NON* 3D-equipped pre-pros -- i.e, the D2v and the AVM 50v without 3D.
NOTE: Manuals, Data Sheets and supplementary literature are now found here:
For folks with the older hardware (original D2, D1, AVM 50, etc.) my usual trick for finding the download links for Manuals and Firmware (search for "discontinued" on the Anthem site) is no longer working. The links found by that search are no good. I'll see if Nick @ Anthem can tell me where that stuff has gone.
ETA: It looks like some of that older hardware stuff is appearing now on the pages linked above, so it may be they have not finished updating yet. For example, I still can't find Manuals/Firmware for the original D2 or D1.
