Tutorial LanguageBreak - Software Jailbreak for (probably) any Kindle <=

[niko]

Thanks for the help mergen3107!

what are the 2 hotfixes you are referring to?
I only know of this:
`Update_hotfix_languagebreak-en-US.bin`

also i need to stop trying things before i ask you guys.
in my attempt to get unstuck, i also did this:

Device Options -> Reset

which i think is a hard reset.

i still can't seem to successfully complete the JB process.

is that what you mean when you say `Factory reset`?

Thanks for the .demo tip!

my FW is: 5.15.1.1
and my device is PW5

This must be #1 rule in the OP for everyone

1) Hofix #1 - Marek's - this relates to the JB.
Htofix #2 = NiLuJe's, this must be taken from NiLuJe's Snapshots thread - take whatever is the newest "JB Hotfix".

2) Yes, this reset is fine, if you can do it. It is the same as putting DO_FACTORY_RESTORE file (no extension!) into the Kindle storage and just rebooting.

3) You didn't install the current FW that supports JB again. Search how to find it here, for example: https://www.mobileread.com/forums/sh...9&postcount=16

So after fcatory reset + PROPER FW (no more than 5.16.2.x!!!), do the JB again.

Thanks so much mergen3107!

It worked!

for anyone else, with similar issue:

1. I updated my firmwire to 5.16.2.1
2. followed the process
(this time i didn't get the Pseudot, but i still selected chinese)
3. got all the nice messages
4. booted into the kindle, and then it got stuck and restarted by itself (?!)
5. i still copy pasted Marek's Hofix #1 -- and i got the mkk folder

kindle looks like this:

audible
documents
fonts
libkh
mkk
rp
voice

my follow up question, which file(s) do i need from NiLuJe's Snapshots thread?

do i just need this file?
KUAL (coplate) | KUAL-5b5d1d2-20231104.tar.xz | 2023-Nov-03 13:37:00 | 73.5K | N/A | Upstream

(my ultimate goal is to be able to read epubs in KOreader)

[mergen3107]

Did you install NiLuJe’s JB Hotfix?

For KUAL, yes, you need coplate version - install via mrpi (which you need to “install” first - copy files from NiLuJe’s snapshots, MR Installer package).

[mergen3107]

Then also don’t forget to install and enable renameOTAbin package to prevent updates.

Tbh my hotfix is kind of redundant now only extra thing it does is switch the language and attempt to leave demo - putting you in weird managed mode, I'm thinking of completely removing it and redirecting users to niluje's hotfix.
TLDR - you do NOT need both.

[mergen3107]

Except for the clean up?

so i will first try to install:

1.

MR Package Installer | kual-mrinstaller-1.7.N-r19303.tar.xz | 2023-Nov-05 13:37:00 | 1.7M | N/A | MRPI

from here:https://www.mobileread.com/forums/sh...d.php?t=225030

2.

KUAL (coplate) | KUAL-5b5d1d2-20231104.tar.xz | 2023-Nov-03 13:37:00 | 73.5K | N/A | Upstream

from here:https://www.mobileread.com/forums/sh...d.php?t=225030

3.

KOReader

from here:
https://github.com/koreader/koreader/releases

is there any guide for any of that stuff?
(first timer here)

i 've seen people suggesting this:

I bought a 32gb paperwhite from ebay with 5.15.1.1 firmware & successfully did langauage break on it, now it's full of kual & koreader goodness.

It's a christmas present for my dad & he's gonna love it

Many thanks for your work & I'm not moaning..

Bloody hell!! you could have saved me some faff if you have said this yesterday lol

First: thank you for jailbreak!


Device is "unregistered kindle"

My problem:

The first 19 steps of the steps detailed in the first post have been completed successfully, with the successful jailbreak message appearing at the top of the screen.

After the Kindle is rebooted, starting in demo mode.

After exiting from demo (with secret gesture):

Settings is inactive
;uzb is not respond
Connect to PC is not activate the USB mode
;demo is not responding
;enter_demo is not responding

Stuck in Demo mode!?

What is the solution?

up1

Tipp from mergen3107: "when you need to copy files the second time (after Resell), copy all files except .demo . This way you won’t get stuck in demo again..."

This is understandable, but how can I start a Factory Reset in this state?

up2

After several tries, the ;demo command brought up the Demo Menu, from which I managed to launch the "Resell Device" option.

The jailbreak is now successfully completed and I have now installed KUAL, MRPI, renameotabin and KOReader.

Thank you,

Regards,
Gabor

I found this post by spacequince very useful which explains in detail how to install Kual, Renameotabin and Koreader. Obviously you will have to install the latest versions of these files.

MR Package Installer and KUAL
MR (mobileread) Package Installer
KUAL (Kindle Unified Application Launcher)
1) Extract mrpackages and extension folders from kual-mrinstaller-1.7.N-r18896.tar.xz to your Kindle’s root folder.
2) Extract Update_KUALBooklet_e3deabf_install.bin file from KUAL-e3deabf-20220213.tar.xz (coplate version of KUAL) to mrpackages folder which is in your Kindle’s root folder.
3) Eject you Kindle and open the search on it and type ;log mrpi (installs KUAL and MRInstaller).
Source: reply by FireFrog on this jailbreak thread, also see next reply by voidnull

renametobin
Prevents OTA updates from Amazon so you can make sure your Kindle doesn’t update which could blow away your jailbreak.
1) Extract renametobin folder from renameotabin.zip to the extensions folder of your Kindle.
2) Eject your Kindle and launch KUAL on it.
3) Tap “Rename OTA Binaries”, then tap “Rename” (Only tap “Restore” when you want to re-enable OTA updates or if you want manually update firmware via "Update Your Kindle" from Settings menu on Kindle)
Source: renametobin reply by re4om on this jailbreak thread

KOReader
1) Extract extensions and koreader folders from koreader-kindlepw2-v2022.03.1.zip to Kindle’s root folder.
2) Eject your Kindle and launch KUAL on it.
3) Tap “KOReader” then tap “Start KOReader”.
4) Wait ~10 seconds for KORreader to open.

If I have 15.16.1 but want to move to latest allowed firmware of 15.16.2.1 (for new scribe notebook features in that release) should I do the jailbreak on 15.16.1 first then flash 15.16.2.1 when I'm done ?

Can I even install new firmware if I haven't gone thru the setup process yet via downloading the right bin file and putting it on the kindle ? I remember doing this

On my KIndle PW5 I first performed the firmware update and then the Jailbreak. For Kindle Scribe mergen3107 has written very detailed instructions on the previous pages that I think will be helpful to you.

[mergen3107]

@arooni,

For your case, it is easier to do JB first on 5.16.1 - because you won't have to accept mandatory firmware upgrade and then downgrade and all those hoops and loops.

Then install hotfix from NiLuJe.
Do not enable renameOTAbin yet (otherwise you won't be able to upgrade).
Turn on Airplane mode.
Upgrade to 5.16.2.0.1 normally.
Then restart Kindle Scribe TWICE.
Then reinstall hotfix from NiLuJe.
Enable renameOTAbin.
