I downloaded the file
https://github.com/KindleModding/Hot...es/tag/v1.14.0
On the Kindle, I restored the OTAs, connected the Kindle to the PC, set the .bin file to root, unplugged the Kindle, and launched the update. When I reorganized, I opened the hotfix book in the library. In KUAL, I blocked updates again.
I tried launching KOreader, but it redirects me to the main menu.
