Chris, I installed the sdk and dfuse on a 3rd pc - windows 7.  Same thing, the netduinoupdate just pegs a core and does nothing.  Not all is lost though.  I was just about to switch over to the pi 2 or my gadgeteer and offer to mail your team the board for diagnostics rather than throwing it away when I stumbled on an older howto for flashing with mfdeploy.  From the firmware download, I renamed the flash file extension to .hex so I was able to browse from mfdeploy and to my complete shock it worked.  I got a small error at the end, but all commands in mfdeploy started working and I was able to deploy my app onto the board with visual studio.  Wifi stayed as yellow and wouldn't connect but I'm suspecting my router.  I will confirm that part after work today.

netduinoupdate on both pc just pegs the cpu and requires a force kill when I hit update.

The continuing saga...

Managed to hit reset enough times and while trying to select erase firmware in mfdeploy that I think I managed to get a command through.  I can now open the network configuration dialog but I'm back to day one where on startup the wifi doesn't even attempt anymore.  When that first happened to me I reinstalled the firmware but I'm still stuck with the above issue with the cpu peg in the updater and it won't do anything.

Some other things when working this out:

netduinoupdate just pegs a cpu and never does anything when I try to upgrade or erase the app (I figured my app had some loop that was consuming everything on the device).  I have a dmp file of netduinoupdate with a pegged cpu if it will help.

in mfdeploy, it connects and shows all the deployed assemblies fine but nothing after that works.  Just about every option under the debug menu results in no reply. I can't even open up the network configuration anymore.  It either gives me a null references exception or I get a message saying it is old configuration.  I've tried both the default mfdeploy and the ipv6 one.

The power led and wifi led are all on when the device powers up.  In the bootloader mode, the blue debug led and power led are both on.

I'm getting a similar issue. I haven't used my board in a couple weeks and when trying on my win10 I can't deploy anymore and mfdeply app fails on most actions I try.  Restarting the board with the button down and running the netduinoupdate it shows the device but I can't do anything and have to force kill.  Figuring the latest win10 build has destroyed my usb drivers (it killed audio and other stuff for me), I switched to my win8 pc.  Netduino update runs on that, shows my board as Netduino 3 Wi-Fi 4.3.22 and I want to force wipe it and reinstall and it just hangs when I hit update.  I'm afraid my board is dead and I've only done one project.
