This, I'm guessing.

Where is the database even stored? I don't think I saw anything that might be it on userstore (and I've checked the hidden folders).

Since you have been so helpful, catching my mistakes when I make them in public;


There are two end-user data storage areas.
One you can see over the USB cable connection and one that you can not see over USB cable connection.

Looking at the file system structure from the "inside" of the Kindle ...
/mnt/us/* <- that is the one you can see over the USB cable.
/var/local/* <- that is the one you can NOT see over the USB cable.

The second one is where the user specific database file live, along with a lot of other interesting things.

And yes, it also gets cleared/reset when you "Reset" the Kindle.

The content collections database is:
cc.db
as named by one of the more creative Lab126 persons.

The name of the interactive SQL application pre-installed by Amazon (available from the Kindle's command line) is:
sqlite3
How to use it (google can probably find you hundreds more) is here:

Okay then: no, never even downloaded the installation files on my pc, let alone the Kindle!

Which does not include /var/local (it is on a different partition).
The Amazon system update images do not include end-user data.
It can't, the end-user data does not belong to them, it belongs to the end-user.

I am not sure I understand what you are conveying with this message.. Anyway, what I meant - excuse my poor english - was simply that I never made use of that booklet, I didn't even know anything about it (nor I never launched koreader on this PW4: I simply installed it because I had it on my PW3), so... it can't be that the "thing" that messed up my database.

Now, everything is fine and as it was, I could very well close the thread. Yet, I am very curious to know what might have happened! Too bad I don't have any log to share of that period!

Thanks.
I do better at describing things than I do at solving problems.
