Hi Jason, this is a little off topic from the original thread, and I'm sorry your ZD won't recover from FDISK reformat and attempt to reload firmware.
We have an article on how to access a disconnected AP during the period it's advertising the recovery Island SSID, before it reboots and starts over.

You may still want to do a factory default and perhaps load 100.1.x.x.x base image, if your ZD was on 9.9 or 9.10.
