Tools Snapshots of NiLuJe's hacks

[toadclones]

I managed to build a python3.11 for hard floating point devices. (firmware > 5.16.2.1.1) This works on my Kindle 11th gen with 5.17.1

I basically took crazyelectron's dockerfile and added preinstalled packages and cross compiles when necessary(numpy). Most packages you would use are installed except pillow(for image manipulation). FBInk bindings are installed.

I included the code used, etc. It's pretty messy. Enjoy.

A list of packages installed

• requests
• bs4
• httpie
• requests_oauthlib
• betamax
• html5lib
• pyjwt
• Wand
• PySocks
• asn1crypto
• SLPP
• cffi
• FBInk bindings

Thanks it worked for me on same Kindle and firmware version.

@NiLuJe Looks like the "developer.keystore" used by KUAL expired yesterday ( April 17th). So Kindles now don't want to open KUAL

Updated with PIL(image library for python, no idea if anyone actually uses it)

Rebuilt both KUAL builds in the first post against an updated keystore (available here).

(It lives in /var/local/java/keystore/developer.keystore)

Had to get creative, so, hopefully this doesn't break on old devices.

Here's a completely untested DevCerts build that *should* update your on-device keystore (and *only* that)...

Thanks for the response. Could you say what exactly we need to update for this to work? I've downloaded your build and replaced the old one with it on Kindle PW2 running 5.4.3.2, but this time trying to run KUAL results in the message "This item is not signed by an authorized developer." Should I have also placed the new developer.keystore file somewhere?

To make sure that the new keystore is installed, I redid the jailbreak following the thread here: https://www.mobileread.com/forums/sh...d.php?t=186645

In the step where we extract the contents of kindle-5.4-jailbreak.zip to the root directory of the Kindle, I replaced the extracted keystore with the updated one that you linked to above. I'm still getting the message "This item is not signed by an authorized developer."

Hi, I jailbroken my PW4, installed KUAL, MRPI, KOreader, KUAL+, Helper+ done. When i trying to install Python and ScreenSavers Hack, i recieved the message: Running install.sh... Package script failed (1), moving on... Failed to remount rootfs RO, waiting... And finally, it's shown Done, restaring UI .... I used 2 file Update_python_0.15.N_install_pw2_and_up.bin; Update_python3_0.15.N_install_pw2_and_up.bin (i tried 1 of 2 and 2 of 2 in /mrpackage). I received text file in /documents: KPPMainAppV2_9112_037-juno_16021_moonshine_rex-428973_crash_Apr_19_14.50.27_2025.txt.

Thanks!

How might I install the new keystore for the kindle 4 jailbreak?

Same issue here on a Kindle 4

[NiLuJe]

I've added an untested package to https://www.mobileread.com/forums/sh...postcount=1295 to update the keystore.

So I figured out what I had to do and downloaded the updated KUAL version with the new keystores. However, when I try to run KUAL I am now getting the error: "This item is not signed by an authorised developer."

Just tried this and it has worked for me! Dropped the K4 file into the root directory and then updated the kindle through the settings menu and I'm back into KUAL and KoReader. Thanks!!

Should have read this, this has fixed it. Thank you!!
