Thanks again for your jobs  |
I can't find how to make this patch work with the current firmware, but I'll describe the problem so maybe someone else can work it out:
When you longpress on a book in the device's library and select view details, a page is shown with a cover image and other info. The root problem is that the device doesn't use the existing cover image with filename ending in "N3_LIBRARY_FULL.parsed" but instead tries to use an identical one with a filename ending in "AndroidBookLoadTablet_Aspect.parsed", and if it is missing will try to download it for synced books or generate it for sideloaded books. This means that no cover image is shown for synced books unless WiFi is on, but it is also a waste of battery to download the cover image each time and a waste of storage space to generate one, when a saved image is already on the device.
Up to firmware 3.2.0 the problem was solved by a patch that simply changed the "AndroidBookLoadTablet_Aspect" string in libnickel to "N3_LIBRARY_FULL". But since 3.3.0 that doesn't work anymore.
However making a copy of the "N3_LIBRARY_FULL.parsed" image file with the name changed to end in "AndroidBookLoadTablet_Aspect.parsed" still works fine, albeit a waste of storage space. (Calibre sends the extra copy of the file automatically if you have the "send covers" option selected)
Edit: I hoped that Kobo would fix this problem quickly because the worst affects are for books bought and synced from Kobo. If you buy your books somewhere else and sideload then thanks to Calibre it is not a big problem, so this acts as a disincentive to buy from Kobo.
Edit2: This is fixed in firmware 3.8.0, so no patch needed.
