I am in the same boat. In my case, I was following the instructions on the Adafruit site for installing a driver that works with their WiFi USB dongle. I was ssh'd into the BBB via ethernet and the power was from a 2A USB power brick. (So no access via the USB port.) The instructions reach the point of inserting the WiFI dongle, then rebooting. When it rebooted, I could not get in via ssh over the ethernet and had no other access to the board. I eventually bailed and pulled the power. I then move over to my bench with a HDMI monitor/keyboard/mouse and booted up there. At that point, the BBB booted, but got stuck at a screen selecting a choice of logins (which I can't remember at the moment) + "other". That last option would allow root for the name, but when I attempted to "skip" the password prompt, it just indicated that authorization failed. Same reaction for the two other names I could log into. In past experience, this usually means the password files have been corrupted. So, I am starting the reflash process. Unfortunately, I get the same thing, it wants to boot to a login prompt and does not enter the flash phase. I am going to completely reformat the SD card (a 16GB Sandisk Ultra class 10), then copy the image again.
If this does not work, I will just install the Cloud9 image on the SD card and boot off of that.
