Troubleshooting KUAL stop working

Everhard · 02-15-2025, 11:38 AM

I recently have jailbrkoen my Kindle Paperwhite 10th gen (PW4) with winter break.

Everything looks grate for a week, I start reading from KOReaeder. Yesterday KoReader has crushed and when I tried to launch it with Kual it doesn't start. I have tried to remove KoReader and re-install program and extension but nothing. Today I have done a fabric reset, I have done again every single step to the jailbreak and everything looks fine. Until KoReader still does not launch.
The write "Starting KoReader" does not appear and the home page refesh with no effect. I have tried to install some other application for kual (kterm and gtkMiners) but they does not start too. Otherwise "Rename OTA binaries" go without problem.

Can anyone help me to figured out and fix the problem?
I like so much KOReader.
Thank you so much

What exact version of KOReader did you download? And from where? What's the firmware version currently installed on your PW4?

My guess would be that you're either using "koreader_kindle2" stable build (that's not armhf compatible) or nighty build that was built with wrong toolchain settings that don't work on PW4, KT4?, Oasis and other "10th gen" Kindle models.

Or you started with older nightly build but then updated it to newer but broken nightly build?
