Hi David @davidbcoulson:
Did you check that the board was operational before trying to load Win10-IOT? Since it appears that you have not yet loaded Win10-IOT, I believe that you should be able to restore dip switch 1 and check that the board is operating (Android takes about 3 minutes to boot the first time, be patient).
I have followed the steps using on my Win7 machine, for me there was one challenge, extracting the ffu file from the iso image (Win7 doesn't automatically mount iso images). To get around this I burned the iso onto a CD, and then coped the ffu file from the CD to local hard drive.
Once you power-up the 410c you should see Windows installing a device driver for the board (under Win 7 it installs "QHSUSB_BULK"). After you start the "DragonBoard Update Tool" it should show a green connection status. if the board is not connected it will show red. You can connect and power-up the board after you start the update tool and the connection status goes green almost instantly. The first time I clicked the "Program" button it failed, but I clicked the button again and it worked fine on the second attempt. Restore switch 1, and re-power the 410c, it shows a splash screen at about 12 seconds, and the core is up in about 30 seconds. Subsequent boots are about 4 seconds to the splash screen and 20 seconds to up and running.
