Mobileread Kindlet Kit

Jes it will... but now I have to understand it...

[Lykos]

Ok but how can it not be jailbroken? I installed the most recent jailbreak and **** Jailbreak **** appeared on the screen. I can mount the filesystem read/write and installed usbnet sucessfully?

[NiLuJe]

Official update/factory reset? Or you misread the error code, because that one is the most straightforward of all: sigcheck failure, which pretty much always means no jailbreak.

EDIT: The only other (very unlikely) possibility is a very specifically corrupted package, and I just double-checked, this one's ok.

[Lykos]

I definitely did not misread the error code, the error code is 007 I just tried again.
I also did just now reinstall the jailbreak, it still fails. An official update is very unlikely too, because everything happened today. Neither did I do a reset.

[Lykos]

Additional Information, the jailbreak was:
kindle-5.4-jailbreak.zip
And the error code is
007 not U007

Edit: Ok I think I will start again from the beginning

[NiLuJe]

You keep mentioning 007, not U007, which leads me to believe you're hitting the factory updater (which doesn't care about our JB), and not the OTA updater, as it should, which would mean you have a stray update*.bin file laying around in addition to the hack's Update*.bin.

Clear the USB root of .bin files, restart your device, and try again (from the Update Your Kindle link, of course).

[Lykos]

ls /mnt/us/
documents   extensions  linkss      python      system      usbnet      usr

There is nothing

[NiLuJe]

Then check the logs to see what the hell the OTA updater is doing, but I'm guessing it's just plain rebooting (for whatever reason) and you're ending up hitting the factory updater instead.

(On the off chance fuse is being dumb, do a real ls with hidden files shown, see if there's a fuse ghost laying around).

[Lykos]

How could one invoke this OTA updater by console?

[NiLuJe]

Check the wiki (or the update button of the KUAL helper extension), but that won't help you, it'll do the exact same checks as from the UYK link.

This should be the relevant part:

Yup, that's definitely a broken jailbreak, and nothing more insidious/weird.

What do you see in /etc/uks ?

[Lykos]

[root@kindle /]# ls /etc/uks/
pubdevkey01.pem   pubprodkey01.pem  pubprodkey02.pem

[NiLuJe]

Huh.

What's the md5 checksum (md5sum) of /etc/uks/pubdevkey01.pem?

[Lykos]

[root@kindle /]# md5sum /etc/uks/*
7130ce39bb3596c5067cabb377c7a9ed  /etc/uks/pubdevkey01.pem
