Might help to see more information. If it were me, with the one that is not working fully for you.
1) Connect a USB cable to the debug port. Start up PuTTY and choose the Serial port associated with the debug port and set the baud rate to 115200 and connect
2) Plug in the other USB port. What shows up in the PuTTY window?
If nothing shows up in terminal window, then my guess is the Edison module is toast (I have one that is in that state that was working earlier).
If you do receive a bunch of debug stuff, does it finally come up to a login prompt? If so it is at least somewhat working. You might try to login to root and see if you can set stuff up.
If it stops at some point without getting to a login prompt, would probably be good to show the details on this thread. On Friday I receive a new board from NewEgg, I tried using the all in one install, which failed on the firmware update. I tried a few things and was in the state here, where the board would not boot enough to allow a flashall to work. I resolved it for my board, by using flashall --recovery on my linux machine, after I downloaded, built and installed the necessary programs. Hopefully you will not need to resort to this...
