Solved this with a little help from Discord Support and passthru to

Basically my kindle (which had been in AP mode forever) decided to pull the OTA within the moments I was online with the store. Annoying feature that, seems like there could be a DNS hostname added or something to prevent pulling in amazon stuff. Anyways, resetting the firmware by grabbing the current version I was on (for my device) from here:

and then following the jailbreak steps from scratch did the trick. Now to learn KOReader and get all the dang books I lost back...
