Try rolling back to v1.33 -- the Official firmware for the D2.
The unit was in to Anthem in February for an HDMI repair. I am pretty certain they updated the firmware to 1.47f at the time from 1.33, and that's what is on the D2.
I tried to downgrade the software using an XP laptop with a serial connection. Got a boot loader error, and Anthem said that's a problem separate from any HDMI processing issue. I don't know if I need to use the Keyspan USB/Serial Adapter to do this, or if there's actually a problem with the D2 preventing me from being able to downgrade, but that's where things stand. I can access ARC via that connection just fine.
In April, Anthem said, in response to the error: "Cannot connect to OKI Boot Loader"
Anthem response: "OKI bootloader means there is something actually wrong with the unit."
But then this month, when I mentioned that the unit had the loader error after trying a lot of other things, I got this response, which we'd covered months ago in the same email thread. Makes no difference. Note the reference to V1.33
"It could be many things.
Once thing I can suggest is a REDMERE cable.
They seem to work great for handshake issues.
V1.33 may not correct the issue.
Usually 1.47f is used when there are handshake issues.
They also recommended Redmere cables, which I'm using. No change.
