Hello... I got a unit in that is stuck in a firmware update loop. The Customer attempted to update the receivers firmware online (using the RJ45 interface.) It keeps complaining about connection failure and just retries. It would seem this is a common problem, but a reset is not breaking the loop. The service manual talks about doing a DFW update using the RS-232 interface. There apparently is an EXE you can get that flashes the firmware directly....a D&M Firmware writer, but I cant seems to locate a copy. Any one have one that they are willing to share?
