CM1000v2 Will not boot

We called Netgear support and they told us to pound sand because the unit was 13 months old and the warranty was 12 months.
I am 99.999% sure that the problem is that the firmware is corrupt and simply reflashing it would bring it back, but Netgear seems to be unwilling to actually do this, preferring instead to just generate more eWaste. What a shame.
If you actually have the CM1000v2 like the title says, it is a cable modem. Refreshing the firmware is at the sole discretion of the ISP, not the cable modem manufacturer.
If you ask technical support at Xfinity, they should refresh your firmware for you.
Xfinity can’t reflash the firmware because the firmware corruption prevents booting at all.
NETGEAR could reflash this unit with the original factory firmware. It’s foolish to suggest that they couldn’t do so if I mailed it back to them. But they simply won’t, preferring that I throw an otherwise perfectly useful cable modem into the trash because it missed the warranty window by 20 days.

With the ISP cable coax line disconnected, have you tried a 30-30-30 reset on the modem with nothing connected to it?

Are you willing to risk the cost for shipping, labor, and etc. to find out the problem is something besides firmware corruption?
Have you tried a different power adapter in case that is the problem?
- I’ll bet you $100 right now that reflashing the factory firmware will fix it.
Yes, I tried a different power supply. I’m not that stupid.
