I have the exact same issue that Adubodub reported. I purchased the unit new last month and attempted to update the firmware to 3474. I do not remember the exact number of the existing firmware on the unit, but it was a much lower number, at least in the 2000s. I used the network method, connecting directly to a computer. I found the IP address fine, got the browser to work, selected the 3474 update file, and then after the status bar completed I had the “system error power cycle dev. and try again” message on the unit, and the browser says “Error writing to flash memory.” I attempted redoing this several times with the same result.
Your suggestion to Adubodub was to contact the distributor. Is that still the only thing that can be done? Can I expect the dealer to know this is a legitimate issue?
