I got the HDX back into Amazon... It's a weird fix.
I did the hold power for 30 second reset thing. After that, I was able to register the device and it retained the Gapps and such. However, all Boot modules like Xposed have been disabled. So it's kinda weird to have to add them back one at a time. And I have to reinstall some apps off GPlay, but that's relatively minor inconvenience when I can often just restore from my TiB backups.
