Question What exactly does the Jailbreak do?

Hey guys - wanting to get started in Kindlet dev (.azw2) files, but I need just a bit of background first. Is this synopsis of the jailbreak correct?

Quote:
Jailbreak exploits a flaw in the Kindle update procedure to add an additional known key to the internal Kindle key whitelist. This allows two things:
* Further .bin-style updates signed with the key, and
* Installation of .azw2 Java apps signed with the key
Yes? No? Are update*.bin files signed at all?

The first point is correct. The second is not. You need to install a java-developer key for that. I never included it because there are many different versions floating around for different apps. Maybe I should include it in the next version.

Ah, okay, makes sense. You could then add a new Java key to the keystore (or just use an existing one): https://www.mobileread.com/forums/sho...d.php?t=152294

BTW I am using niluje's jailbreak, I assume it works similar to yours.
