My apology for my stupid noob post. It clearly stated the correct order in the instruction documentation.
This is how I, as an absolute noob, read your instruction:
Page 1: Getting started
(https://duet3d.com/wiki/Duet_Wiki)
Page 2: Checking firmware (https://duet3d.com/wiki/Checking_the_firmware_versions_and_updating_the_firmware)
Page 3: Updating firmware
(https://duet3d.com/wiki/Duet_Wiki#Updating_Duet_WiFi_firmware)
Choice 1: updating the main firmware
Choice 2: updating wifi firmware or DWC
Choice 3: updating more than 1 firmware
Here, not knowing what I am doing, I made the mistake of picking choice 1. That is my first wrong choice, although I am not quite sure how I would know to pick choice 3 at the time.
Page 4: Instruction on updating firmware

Oh by the way, so the instruction goes, I can download multiple firmwares as well. Stupid me downloaded all three available firmwares. No where on this page or the github page is there any warning that these must be installed in order. Your single line warning here would have bailed me out. Alternatively, I should have went back a step to "updating more than 1 firmware" to get the warning before proceeding. I am not quite sure how I would know to do that.
Anyway, the installation obviously did not work.
In my frustration, in an attempt to reset the board, I accidentally hit the erase button. Fatal mistake!
I should have read the forum before reading the installation instruction.
Now I am sitting here patiently waiting for Atmel to send me a link for SAM-BA. . . and have too much time for stupid noob posts.
