Intitial testing for enabling hidden notebook on kobo libra 2.

[Pololot64]

I did some basic research. This lets you open the notebook "app". The app doesn't function properly, however. You also cannot draw on pdfs.

Thanks! I will take a look at this when I start working on the patch updates for the latest release (I've been away recently).

• Documentation.
• Use "notebooks" as the name for consistency.
• It's _ZN15LibraryNavMixin13showNotebooksEv from 17623 to 19086, and _ZN14MoreController9notebooksEv from 19501.

_ZN15LibraryNavMixin13showNotebooksEv @ 19086	_ZN14MoreController9notebooksEv @ 21908

Is it best to write it only for the newer build versions or should there be a build check?

Try loading both (newest one first), and if one is null, then use the other. Something like:

else if (!strcmp(arg2, "notebooks")) sym_f = dlsym(RTLD_DEFAULT, "_ZN14MoreController9notebooksEv")
    ? "_ZN14MoreController9notebooksEv"        //libnickel 4.32.19501 * _ZN14MoreController9notebooksEv
    : "_ZN15LibraryNavMixin13showNotebooksEv"; //libnickel 4.28.17623 4.31.19086 _ZN15LibraryNavMixin13showNotebooksEv

Just pasted what you said :) I don't speak cpp yet. Let me go test.

I have a question, I found the original string (that turned out to be wrong) by fuzzy searching in compiled binaries pulled out of the firmware. Is there a better way?

[Pololot64]

So, it seems that kobo is smarter than that. As before, I can open the notebooks app. The problem is that on the creation of any note, the device requests to download the handwriting recognition pack and fails in a loop of try again dialogs. I cannot think of a way around this.
