Conversion successful, but "Cannot Open" on device

HFC3 · 04-11-2013, 01:18 AM

I know I've used Conversion before (PDF to Mobi, and I think MOBI to MOBI (to remove bad formatting and extraneous spacing)) without a problem. That was at least 2 versions of Calibre ago (before 0.9.25), though.

This time, though, when I converted a book in v0.9.25, I got a "Cannot Open. If you purchased this from Amazon, delete this book and re-download" error when I tried to open the converted book on the Kindle. I downloaded v0.9.26, and get the same results. In both cases, the converted book opened without a problem on the PC.

I've tried converting to several formats (MOBI to AZW, MOBI to MOBI, MOBI to PDF, PDF to MOBI, PDF to AZW), with the same results. I've also tried with varying conversion options (Remove blank lines, Font rescaling, as well as well as "default"), and still get a good PC conversion, but unable to open on device.

I've also reviewed the conversion debug information, and everything in there looks fine. That would make sense since the newly converted book opens on the PC.

Has anyone got any suggestions on
a) What I can do to debug why the converted books will not open on the K Touch, and/or
b) What I may be doing wrong in the conversion process?

Thank you!

You probably changed the mobi output to produce joint KF8/mobi files. Convert to azw3 or return that setting to old.

How do you even set it up for joint MOBI/KF8? I don't see a KF8 format in the conversion settings anywhere. I'm assuming this also means you can convert to MOBI/{something else}

I did try converting to PDF and back to MOBI after resetting my MOBI to Defaults, if that's what you're talking about. I still get that error.

I just tried it again, and I was wrong - I hadn't reset the MOBI output to defaults, only the common ones. After resetting that it worked. Moving forward again, all the options worked fine until I changed the "MOBI File Type" to "New" or "Both" - is that what you meant by KF8?

Anyway, with that set to "Old" it seems to be converting properly again!

Thanks for your help!
