After trying every tutorial and forum thread I can find, I will admit that I now need to ask for help.

N9: Singapore Black 16 GB (059J246)

I received it new when the phone was first released. We used it for a day loaded up some software, then tried to wipe it to bring it back to factory clean after we ran into a problem. It never came back up. That was a while ago and I don't remember the details. I had other new phones at the time and was traveling, so we didn't get the phone fixed. The phone now gets caught in a loop of Nokia screen / reboot.

Since then I've tried various things from this discussion board and elsewhere. Here's where we are now:

When I try to flash the device using the Navifirm downloaded images for the variant on Flasher 3.12.1 on both Mac, PC and Linux, here's the output:

Where should I go from here? What answers can I provide to hopefully find a fix?
