Alright, I tried your suggestions, but achieved the same results. The receiver enters a retry loop. It does seem as if the receiver actually download and installs the update as the firmware version afterwards is 0007. Additionally, the "friendly name" shows on the network after the update, whereas it did not show before the update (reset net card to version 0000).

It is as if the receiver downloads and installs the version 0007, but a glitch in the software fools the receiver into thinking the download was incomplete, and enters the eternal retry download loop.

What is next?!?!
