Installing / Using KOReader

tedtedted · 02-17-2025, 05:00 PM

Howdy folks. After reading about sideloading being disabled in a future update, I decided to jailbreak my kindle today.

The model is PW4 and I followed these instructions to the letter:
https://kindlemodding.org/jailbreaking/WinterBreak/

Everything went pretty smoothly, with the exception of the KUAL install which included a few lines that were roughly 'failed to remount rootfs RO' and 'reboot recommended', however the install ended with a success message and returned me to the UI with KUAL seemingly operational.

I installed KOReader version 'koreader-kindle-v2024.11.zip' from github. It appears as expected in KUAL however all the options (start koreader, start koreader (ASAP), start koreader (no framework)) just put me back at the homescreen without it fully starting.

Any thoughts on what I did wrong here? I also tried reinstalling KUAL (coplate) from MRPI with no difference in outcome.

Cheers!

Well, thanks for letting me rubber ducky here... looks like I just installed the wrong version of KOReader.

I wanted koreader-kindlepw2, as detailed here:

If your firmware version is 5.16.3 or higher, you will need the hf (hardware floating point) version of KOReader. As of today, the nightly version is koreader-kindlehf-v2024.11-206-gb8a31ef18_2025-02-15.zip. The stable site does not include any kindlehf versions. I originally used the version from Marek's khf site https://fw.notmarek.com/khf/koreader/

Thank you, that was the ticket. FWIW the latest nightly build from the official github worked for me.
