Where does Kindle store WiFi logins?

[toothless]

Does anybody know where the Kindle stores its past Wifi logins? I want to clear the login info so that I don't accidentally take it off the airplane mode and let it get updated.

I have a PW3 with firmware 5.6.5, jailbreaked. I checked the usual places where Linux stores its Wifi networks (/var/NetworkManager) but couldn't locate it.

Well, it is safe ATM to let it update, actually. The current released jailbreak is pretty resilient.
For another thing, you are on the latest currently-existing firmware.

You can enable WiFi, then select the currently-connected network and choose to "Forget" it.


What files to delete if you must do it via the shell?
Well, pretty much anything in the system partition that has user-specific data, is in /var/local/

I *think* it (WiFi logins) is contained in /var/local/system/wifid.conf

Thanks, looks like wifid.conf was the right file!

On another note, why do you say the current jailbreak is pretty resilient? Aren't the updates now going to be an entire re-write of the system? How can any modification remain in place if that is the case?

P.F.M.
Plus, NiLuJe has had a lot of practice by now.

Note:
All series 5 devices since 5.3.2 (IIRC) have received complete ('main') system replacements of the **AMAZON** portions of the file system tree. (The Kindles are 'dual-boot' devices - like having WinXP and Win10 on the same machine.)

The jailbreak is stored in /var/local which isn't touched by updated (because it basically has user-specific data, not OS data ) and is restored on every boot when the Kindle startup scripts source /var/local/system/fixup. That is how it survives firmware updates.

They surprised everybody when they made the Kindle actually use a root account -- the jailbreak was still there, but useless without a way to elevate to root. That's where "gandalf" comes in, our friendly neighborhood passwordless su binary.

Now, the jailbreak also sources an emergency.sh file if present in the userstore, although I am not sure exactly how Amazon could one-up the switch-to-root move.
Of course, they still might wipe /var/local but there are reasons to think they won't go that far.

...

As knc1 said, every update since the KT 5.3 days has been a full system image. There are still some partitions of consequence that don't get overwritten though.

Got it, thanks for the explanation!
