KV updated.

[Akirainblack]

Hi All,

Been away from the forums for a while and whilst I thought I was protected with a dummy download file with modified permissions I was obviously wrong.
My Jailbroken KV updated today to 5.12.3.
I knew there used to be a way to redo the jailbreak but despite my searching I can't find it.
I also seem to remember it stopped working a while back and you needed to downgrade to reapply the jailbreak.
Does anyone have any guidance on this please?
I've looked in the KV wiki but that is just a placeholder and as I said I've done various searches but haven't happened across the information I need.

Thank you in advance.

Akirainblack.

And if reinstalling the Hotfix fails: https://www.mobileread.com/forums/sh...d.php?t=325477

Thank you, as always, NiLuJe! I'll try that as soon as I get home today and update with my success /failure. About to go on holiday so need my kindle. ��

The jailbreak fails with error 007.
The emergency.sh appears to work
I've extracted the mkk to the mrpackages folder and issued the ;log mrpi command.
The kindle reboots but when I try to run KUAL it gives me an application error.
Tried installing both KUAL_booklet and KUAL_booklet_hotfix with no luck.

;log mrpi reboots the Kindle in case that helps.

Any advice please?

Thank you hius07 I followed that, however get an error 007 when I try to install the KUAL coplate update as an update. I've also tried installing it via mrpi but still an application error.

After error 007 do the following
- restore ;log mrpi command (the link above)
Copied emergency.sh to root of kindle and restarted - 3 files successfully created.
f:\done_emergency.sh
f:\new_debug_cmds.json
f:\old_debug_cmds.json
(attempted with and without a second reboot here)
- download K5 JailBreak archive
downloaded kindle-jailbreak-1.16.N-r16683.tar.xz
- take Update_jailbreak_bridge_*_install.bin from the archive and install it via ;log mrpi
followed step - f:\mrpackages\Update_jailbreak_bridge_1.16.N_insta ll.bin - ;log mrpi
kindle reboots bar fills.
- install KUAL hotfix (from KUAL coplate archive) as update
Downloaded KUAL-f54e864-20191030.tar.xz and extracted the hotfix file,
f:\Update_KUALBooklet_hotfix_f54e864_install.bin
attempted to install as an update.
- Settings -Update your Kindle.
Update Error: 007

[NiLuJe]

Err, define "reboot". It should absolutely never ever actually reboot when running MRPI.

You might want to try updating MRPI first, in case you have a dodgy version.

In any case, sounds like it's been killed dead.

[Akirainblack]

Type in ;log mrpi and hit the arrow.
keyboard disappears
screen briefly goes white
goes to the kindle screen with the person reading under a tree and then the bar fills up.
Back to the home screen.

Bah, that sucks, thank you anyway both of you.

[NiLuJe]

Do try updating MRPI, but that vaguely reminds me of what happened when the whole noexec stuff hit, so that probably won't help.

[Akirainblack]

Thanks again NiLuJe - I have already tried updating MRPI but nothing changed.
I thought that if the emergency.sh script worked and created the 3 files at least some of the Jailbreak had survived? I only truly care about the screensavers TBH, anything else is a bonus, I just can't stand the stock ones they're horrible.

[NiLuJe]

The emergency script can't do the required changes if the remnants of bridge are too old .

[Akirainblack]

Once again thanks NiLuJe. A real pity, but your help as always is greatly appreciated.

[Akirainblack]

I take it I can't downgrade using a factory image and jailbreak again that way?

[NiLuJe]

Nope.
