You can grab the "original" eMMC flasher here: https://debian.beagleboard.org/images/BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz NOTE: it will 'boot' to a desktop and start flashing the eMMC, just wait for it to shutdown. (i think the desktop says "this is a temp session", or something.) it's flashing setup was totally un-reliable in the end and we moved to a different method a few months later, which you see documented.
