If what you need is to have a backup of your Edison, I would suggest you to take a look at Edison backup? and How to install a kernel from my repo onto Edison with the official image on the first part of the tutorial AlexT explains how to create a backup of your Edison's data.
Having an answer to this would be really helpful. The other methods of getting an image off of an edison aren't great (setting up and booting from an sd card is quite the process, and dd'ing a running filesystem isn't ideal), and just using the same tool that flashes an edison makes sense.
When I try this, I run `run do_flash` in the U-Boot shell. Then on my computer:
sudo dfu-util -v -d 8087:0a99 --alt rootfs -U edison.root -Z 1610612736
which results in:

My only guess is that `do_flash` is not the correct thing to run. Any thoughts on this?
Also, sorry about the formatting. No matter what I seem to do in the editor it isn't reflected in the actual post...

I've been doing some research and as you mentioned do_flash won't help if you try to backup your Edison. Unfortunately I found that the method found in https://communities.intel.com/message/255608#255608 is currently the only way to backup the image.
