Thanks! Most surprisingly, it's exactly the same as the one from Frank. That's good news for the community, now we know.

It does however pose more questions, why now are the image locations different from the u-boot defaults? How do you change the pboot image locations? Why do the u-boot image settings change after a firmware update attempt? How do you change the u-boot defaults? What else needs to be programmed to perform a factory firmware update?

Cheers

This is starting to get interesting.

Restored the proper mac and the dummy serial # MY99999999. Also added a new unique GUID. I think the only value that is used is the MAC address. So the 34461A is happy again. I am pondering options to nuke the serial/model on the 33622A still though.

Awesome, glad to hear things are back to normal.... errr pre-factory info

So your 34461A works, but only if you tell it where to boot the image from manually?
