Well, I finally bricked one of my Edison's. That was the bad news, but the good news is I found your post. Since I had a spare 32bit machine with Ubuntu 14.04 installed, I didn't go the pendrive route. I did have to install xFSTK and dfu-util. After extracting the latest image, I ran flashall.sh -b. The flash process seems to work OK, but I'm still not ending up with a working Edison.
Maybe I should backup and confess I bricked it by installing ubilinux. I'm not sure I got a good install of ubilinux for one thing. It basically worked, but I was never able to get a Virtual Com Port to show up nor was I able to get WiFi working. The fact that I lost my Virtual Com Port during that process might be at the heart of why now I can't get reflash this Edison. Since it has no Virtual Com Port, it also has no Edison drive. Now I can't seem to get it back.
Anyway, when I use your process to try unbricking it, I get the following messages:

Your board needs to reboot twice to complete the flashing procedure, please do not unplug it for 2 minutes.

As far as I can tell, it never reboots once let alone twice. In any case, if I eventually power cycle it, I get the following:

It always stops at this point.
If I try bringing it up on my Windows machine, I can never connect.
Any thoughts as to what else I can try?
BTW, I have both Arduino and Mini breakout boards. I also backed up my working Yocto image to a SD card before reflashing to ubilinux but can't find a way to use my backup in this situation.
