Note that the BBB is picky about power supply when flashing eMMC: the 500ma from a USB might not be enough, so plug it into a real power supply, then boot from the "flasher" SD while holding the SD boot button down until after all 4 leds light up.
I also note that you didn't really erase your eMMC, or you wouldn't be getting a shell prompt of any kind, you'd just be getting the TI chip sending the letter "C" over the serial port repeatedly, waiting for you to send it boot code. Since you get a prompt, I'm assuming that's the u-boot prompt having been loaded from the first partition successfully, and then failing to find the kernel on the second "root" partition. If that's the case, it might be easier to restore that partition by copying files over to it rather than reburning.
