Going via "kobo12/Aug2025/qt5-qt6-5.10.226356/KoboRoot.tgz" seems to have worked, I'm running 4.45.23697 via OTA now. Thanks for the advice, when I read the github I assumed the conversion step was only needed for 4.X -> 5.X. It was not clear to me it is needed the other way around aswell.

What I did was:
1. Reset to 5.13.241423
2. Enabled dev mode (via update.tar)
3. Swapped to kobo mode
4. Grabbed "kobo12/Aug2025/qt5-qt6-5.10.226356/KoboRoot.tgz" and copied the update.tar + two files next to it in .kobo. This put me on 5.10.226356.
5. Used the DowngradePackages update.tar to go to 4.40.23081.
6. Rebooted e-reader
7. Installed Updates via OTA. Now on 4.45.23697.

Thanks a lot Waldy!
