Kobo freezing after transferring ePub - Page 2

Great...done...done...and done. I deleted all the items I had added directly from the device drive and the processing problem is no more. I will add back carefully and see who the culprit is.

Thanks again,

Jim

I have tried, sometimes unsuccessfully, to be patient with the flaws attached to the Kobo Reader. But . . . now am totally frustrated. Purchased a book from Kobo Books. Added to my Kobo library; used "sync" to install on my Kobo reader. Unplugged from computer. Took an inordinate amount of time to process and did not actually complete. Did a "reset." Screen is frozen at "Kobo, eReading; anytime, anyplace. Had fully recharged prior to loading newly purchased book but in the event that lengthy processing time had drained battery, attempted to recharge but screen doesn't register that Kobo is plugged in. Any ideas?

Try to delete the latest book that caused the problem directly from the kobo, assuming that the kobo shows up as a device on your computer. This worked for me when I deleted a book that I had tried to add. Then maybe try to load the book directly from ADE or calibre.

Thanks for the input. I have already tried deleting the book and then copying directly from "Digital Editions" to Kobo (cannot add using Calibre since book has DRM) but reader does not process any books at this point.

Returned Kobo Reader to Chapters today. Nothing suggested here or by Kobo's customer service proved successful.

I have the same problem, except I know exactly which book is causing it. It is Art Of Agile in EPUB format from Oreily books, which I purchased directly from them.

The Kobo will eventually finish loading the book (it takes about 15+ mins) but then even reading it is exceptionally slow and basically it is unusable.

I used Calibre to do a EPUB->EPUB conversion, which actually made the file size larger, but it allowed it to load in about a minute instead of 15 (still slow but bearable). Changing the font takes a long time and is broken through (Will try running the font fix after Calibre instead of before it this time). It also broke the chapters.

This EPUB is perfectly readable in ADE and Calibre, it passes the validator, there is nothing at all wrong with it. If the firmware release tomorrow does not fix this it is going straight back to Chapters and I'm placing an order for a Kindle. No company should ever be allowed to release something as broken as this is.

Edit: Actually something that could be a factor is the book has a lot of chapters organized in a hierarchy. The Kobo isn't displaying all of these chapters or the hierarchy, perhaps it is just too much for it?

Edit 2: Ok performing these steps has had the best result so far:

1. Add the epub to Calibre
2. Peform Epub -> Epub conversion in Calibre
3. Run the resulting epub through the font fixer

I can now load in a reasonable time and fix the fonts. This book has 63 pages of chapters (683 chapters) basically because it has a lot of individual section which are being interpreted as chapters and the Kobo has no concept of the hierarchy (a pretty glaring oversight if you ask me). My best guess is this is leading to some of the loading slowness, if anyone knows how I can use Calibre to cut out some of the chapter marks for the sub-sub-subsections that would be appreciated.

I had the same problem adding epub files that were downloaded direct from a publisher to my Kobo Touch (firmware 1.9.6). After adding a new book by dropping it on the Kobo, ejecting and unplugging, the Kobo would spend forever "Processing Content".

I installed Calibre (0.8.11) and doing the following helped:

First Calibre found about 20 titles on the Kobo that I had never seen on the device. These had install dates of before when I bought the device, although I bought the device new. I deleted these using Calibre.

Second I used Calibre to do an epub to epub conversion of the file and upload the new epub file to the Kobo. After ejecting and unplugging the Kobo processed the new book in a few seconds.
