Anyone have any tips?

yes.

Do not do this:
I hit the power button and nothing happened, but I could hear the fans whirring, so I held the power button down to power down the computer, waited a few seconds, then turned it back on.

when updating firmware. The worst thing you can do when updating firmware is to not let it cook through, or interrupt the installation, power down and back up. That is just asking for a brick.

Don't second guess the firmware upgrade. Let it do its thing... it will sometimes take awhile, reboot itself to apply the upgrade, and then reboot itself again. The last thing in the world you wanna do is "hey... maybe this isn't working right... I'll try a hard power down and see if that fixes it." Major facepalm there.
