This just started the other day. I _think_ it may have been after a brief power outage, but I didn't notice until later. You can see a vid of what's happening here:

It acts like it's just rebooting constantly. The white world light flashes for a bit, then goes red solid for a couple seconds, then white flashes, then red briefly, then it repeats. On the back, after it goes red, all of the ethernet LEDs flash, which I think means it is starting up?
It never appears on WiFi, and even plugging in, I never get an IP address.
I have tried manually resetting to factory using the button, but it seems to have no effect. I've tried plugging it in to different plugs, too, just in case it was some power oddity.
I'm guessing maybe a firmware update got interrupted maybe.
Are there any further measures to try or is this one probably just hosed?
(Note: I am a software developer and relatively competent with networking, FWIW.)
