Your best bet for learning about what is being done is to look up the original "de-bricking" threads.
In those, people had to do all the commands "by hand" without any automation to help.
The Kubrick "Wizard" just (no offense intended ixtab) automates the process.
Making it much easier on the end-user but less informative. 
The Kubrick LiveCD has most of those 'old' utilities already built and installed (has to, since the 'Wizard' uses them).
ixtab has include an escape from the 'Wizard' to the command line shell in Kubrick.
(Check his documentation - I don't recall what it is.) |
Alt+F2 it is
But yeah, knc1 is absolutely right. To the best of my knowledge, nobody has yet kept a copy of the demo firmwares. One could extract it from a demo Kindle by starting Kubrick up to the point where usbnetwork is enabled, then switching to a full console, ssh'ing to the kindle and manually making backups of the main kernel and partitions 1,3, and 4. And one could restore these manually afterwards.
