Kindle Removal Drm Error: .azw4 (New extension?)

[willitoo]

I've been around the forums a bit, and finally came to a problem.
The book i bought was a .azw4 file (I suppose a new extension)
the tools didn't recognize them.

I renamed it to .azw and it took a while but processed out a file, but when opening in Calibre it shows the cover & the second page being random letters/symbols (metadata?)

Has anyone come up with an idea for this, or hit the same problem?

What version of Kindle software and what OS do you use?

Have you tried to download the same book with an older version of a Kindle app?

Hi,
If the tools did not provide a bunch of error messags, then I doubt this is any completely new format. My guess is that either you are using an older version of the tools or this file has slightly different handling of the encoding or trailing data info than what the tools expect.

Please make sure you are using tools_v4.6 and that you have removed any old K4MobiDeDRM plugins and Mobi plugins from Calibre. If you still have problems, I would do as the plugin ReadMe states and try the calibredb add command to generate a log of the error messages and post them to the comments at the ApprenticeAlf blog where the authors of these plugins can see it and have a chance to look at it.

Asking at the source of the tools (where the tools authors can be found) on the ApprenticeAlf site is a better place to get these types of problems resolved.

I do have the 4.6 tools & i'll do the calibre command to obtain the errors. Thanks

K4MobiDeDRM_v03.5_plugin was announced to support Kindle for PC 1.6.0, but it even works with my k4pc 1.6.1. So try a newer version of k4pc.

Which book? Without seeing a sample it's hard to say what's going on.

I have the same issue; it occurred for me on this book: http://amzn.com/Advanced-Engineering-Mathematics-10th-ebook/dp/B005G14K86/ To be clear, this issue appears with the purchased edition of the book, as opposed to the rented version. I suspect that this new format may be linked to the fact that the book can only be read using the Kindle for PC program-- it won't transfer to an actual Kindle device (I wish that Amazon had highlighted that before I payed for it).

I downloaded the latest version of Calibre and the tools (4.6). I'm guaranteed to not have any issues with previous installs, as I had not used either tool before. Like willitoo, I had to rename the .azw4 file to the .azw extension for it to be recognized. After importing, the file showed the same issues described: the cover was successfully converted, but the remainder of the text was unconverted.

I'd be glad to help someone more knowledgeable solve this problem. If it would help, I can dump the first page of the unconverted portion to pastebin or somewhere.

I note that there's an interesting addition to the description of the book:

Print Replica: This Kindle book looks just like the printed book
Read it exclusively on Kindle for PC or Kindle for Mac

I can only suppose that this is some new format, and is unlikely to be handled well by the existing DRM-removal tools.

It is a new format. See

I'm sure the current tools won't work properly on them. I'm not sure the current developers would be interested in removing DRM from rented books, and it seems likely that any tool that could remove the DRM from purchased "Print Replica" kindle ebooks would also work on the rented versions.

Amazon do offer refunds on Kindle books, so I'd suggest that anyone who's unhappy with DRMed books should return them for a refund.

Why in the world would Amazon sell an ebook that can't be read on the Kindle? Isn't that limiting their sales as well as a slap in the face of all the faithful Kindles fans? I don't get it.
