Amazon uses a full image of the system partition for their update.
"That" is what over-writes the keys.

With the order of:

• Reset
• Image update

You are back to Amazon 'stock' state.

With the order of:

• Image update
• Reset

(An image update ends with a system reboot, which runs the automatic re-install code for the keys (all of them) ).
That is, the jailbreak and its supporting files makes the jailbreak "viral".
You don't install a jailbreak to a Kindle, you infect the Kindle with the jailbreak.

So once the system is back up, where you can press "Reset" the keys have already been restored.

All the above action order does is wipe everything EXCEPT the keys. So this order of actions can be recovered from.

So the simplest advice to give anyone other than a system developer is:
"Do not ever touch 'Reset', never, ever. "

Thank you for your elaborate explainations. So a jailbreak bridge is a script that runs just after a firmware update. **---deleted for safety---**
Yes I enabled parental controls which can prevent everyone from touching that never touch button.


I WOULD RECOMMEND EVERYONE TO ENABLE PARENTAL CONTROLS ALL THE TIME LOCKING SOMETHING LIKE GOODREADS WHICH THEY NEVER USE. THIS COULD PREVENT ACCIDENTAL TOUCHES. BUT WATONLY TOUCHES MAKES YOU SOL

Thank You,
