Home Assistant Blue not responding to voltage select

Had a power outage at the house recently, and soon afterward my Home Assistant Blue stopped responding. I went to check on it and it was really hot (much hotter than it normally gets). Let it cool off for a couple minutes unplugged, then plugged it in with a monitor attached, and now I get the following:

Board variant: n2-plus
Net: Could not get PHY for mdio@0: addr 0
No ethernet found.

Card did not respond to voltage select! : -110

Any idea how I can resurrect this board? Or is it shot?

Some Googling suggests it might be your e-mmc that is the problem.
