In a terminal window (thanks .torrent), I typed: adb devices (then sudo adb devices) and got nothing in return.

I've tried sideloading; the ROM loads according to the terminal window, but I don't see anything happening on the phone (no failures though).

I've tried pushing a ROM to the phone but the terminal window says that it doesn't see the device. That doesn't make sense because I can sideload (apparently).

ugh.
