Bricked BBB during reflash

I attempted to reflash my BBB for Volumio and it failed somehow and hung. After a couple of hours I unplugged it and retried. Now I cannot get it to begin to reflash. Although I hold the button upon start, it never seems to start the actual re flash sequence, and I never end up with the four solid LEDs. If I use an IP scanner, it shows, but it will not do anything. I assume I corrupted the eMMC, and would appreciated some guidance as to how to proceed. Thank you in advance…
