Quick question: I've looked through a fair bit of the documentation in threads.

It doesn't seem like that'll get it out of what's causing it to hang, but I haven't seen how to get it reset in a way that backtracks a bit.
I'm assuming I just haven't happened upon which post outlines what more you should do via serial.
Thanks for any hints!

Correct - a variation on the procedure in the 'Serial JB' thread.
I do not think anyone has written up that variation yet.
Only big deal is to use KindleTool to open up the update_*.bin file for the downgrade of your device, and dd the rootfs file onto mmc0blk1 then reboot.
OR -
just escape from the boot sequence into u-boot and get u-boot to install the downgrade update_*.bin for you.
Like I wrote, a variation on the procedure but I don't have time to write-up the details.
