(PW4 Jailbreak) Calibre manage libraries > Only 1 book found

[Cecile87]

Hi guys,
I just jailbroke my Kindle PW4 10th gen (FW 5.16.2.1.1, LanguageBreak), and I have an issue related to either the jailbreak itself or KOReader (or possibly Calibre?), can't tell exactly which one, so I'll post in the KOReader section for now.

So the Jailbreak went fine, installed KUAL + KOReader, all good.
Then I proceed and try to load Calibre metadata the regular way:
"> Settings > Calibre > Search settings > Manage libraries > Rescan disk for calibre libraries"
By doing this, I get the message
"Found 1 calibre libraries with 1 books"
"/mnt/us"
The problem is I sent ~2000 books to the Kindle, not just 1.
And funny enough, trying to read that 1 detected book, it exits KOReader and crashes to Kindle splashscreen.

I'm used to follow the same exact procedure with my Kobo Aura (in Calibre, selecting all the books I want to stock there "Send to device" > Wait for all tasks to finish > safe eject), and KOReader has no issue loading the metadata there for all the books.

-

Some things I noticed:
> If I try to load "only" 500 books (whatever which books), everything works flawlessly, so it doesn't seem to be one book in particular that causes a problem.
On the other hand by loading 750(?) or more, then KOReader only finds 1 book (that book always seems to be the most recent selected). And by loading that particular one, KOReader always crashes.

> Reading the books (whatever one) by manually browsing inside KOReader folders and opening them works, it's just the metadata that doesn't wanna load properly.

If someone has a clue that would be kind to share, thanks

I've modified the metadata.lua file accordingly (my db file is 86MB).
Still the same error, any other clue?
Thanks for your input

 It's a scroll... It's a codex... It's KOReader!

Edit 2: It worked very well with this method pazos, just has to actually reboot twice before it took effect!
Thanks very much for your help, hours of reading ahead!

Great, remember you'll need to do it again after each update.

Or you can create a copy of the calibre.koplugin folder with another name. See https://www.mobileread.com/forums/sh...28&postcount=2
