Hello, ask, I installed the KUAL plugin at
https://www.mobileread.com/forums/sh...&postcount=304, then used this plugin to install kpvbooklet 0.66, and then downloaded the KOReader Kindle in November 2018. The package, copied to the root directory of the kindle, open the KUAL plugin to see KOReader and his function options, but click on the file to browse and open the document can not be used, always flash back, copy the epub e-book to the Kindle root directory In the document, it will not be displayed after disconnection. I can see other people's posts. If KOReader is installed normally, you can see the epub e-book on the homepage, but my KOReader is always unavailable. The Kindle firmware is 5.10.0.2. There is a problem in one step, how to fix it, thank you!
