Amazon Kindle issue

[bookworm17]

Having a problem with Amazon Kindle. I did the full remove from Amazon, uninstall, reinstall, etc already. OSX 10.12.4 (16E195). Kindle app from Mac App Store. Calibre 2.71

I don't believe these tools work with the Mac store Kindle app. Try installing Kindle for Mac version 1.17. See the FAQs here:

https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#a-recent-change-to-kindle-for-pckindle-for-mac

(Be sure to uncheck auto-updates.)

Hmm, it was working fine with the (earlier versions of the) App store Kindle. Note that the App store version stores its content in a different place, but I was using it fine.

In any event, I removed that version and downloaded 1.17.1. Still doesn't remove the DRM.

[ElleKayEm]

I guess someone must have just been speculating about the Mac Store app then. Post a log of an import with a freshly downloaded book from 1.17.

Here is the debug log.

[ElleKayEm]

Somehow it's still not getting the right key. When you reinstalled, did you follow these instructions from the FAQs for removing all associated folders? And the book was definitely downloaded with the new installation?

[bookworm17]

Yes, but I will repeat them tomorrow (not time today).

[bookworm17]

still a failure

Let me ask @pdurrant to take a look. Maybe he'll see what I'm missing. He's also a Mac user so he might have a better idea.

[pdurrant]

How very strange. What Mac is it? Does it have multiple internal hard disks, or multiple ethernet ports? I beleive that the decoding of the Mac key uses some ID numbers from the hard disk or ethernet port, and perhaps if there are more than one of either it's finding the wrong one.

I think you'll need to wait for Apprentice Harper to chime in on this one.

[bookworm17]

Here's the full information on my Mac. Note that everything was working fine - even with the Kindle from the App Store - until I upgraded to OS X 10.12.4.

Mac mini.spx.zip

[bookworm17]

For what it's worth, I tried a fresh install on a new Mac. (Not convenient for long-term use, but ok for testing) and it converted fine.

[apprenticeharper]

If your Mac Mini has any external drives (e.g. DVD-R), try with them disconnected. I haven't had other reports of problems with 10.12.4 as far as I remember, so it's probably something peculiar to your setup. Have you tried in a new user account on your Mac Mini?

[bookworm17]

Yes, it has several (:-). However, I'm pretty sure that we've already established that it's a user-account related setting/piece of configuration. The question is what setting?

[bookworm17]

I went through and cleaned out and reinstalled from scratch. I even found a few extra Kindle files under Preferences and removed them. (Essentially, I looked for anything under ~/Library that had "Kindle" or "kindle" anywhere in the name.) Still failed.

I did set up a second user on my main Mac and was able to convert fine. So, this is a less-painful workaround.

I'd really like to get this working properly. Ideas?

[apprenticeharper]

On Windows having a short user name containing non-ascii characters will cause decryption to fail. Perhaps this applies on Mac too?

Otherwise, I'm out of ideas.

[bookworm17]

User name is "craig". (:-)(:-(.

[ElleKayEm]

For whatever reason, the key file is found, but it can't be decrypted. In the last log you posted:

Found k4Mac kinf2011 file: /Users/craig/Library/Application Support/Kindle/storage/.kinf2011
Couldn't decrypt file.

Normally it would say:

Decrypted key file using IDString ‘some string of characters here’ and UserName ‘craig’

So it seems to be having trouble figuring out whatever IDString is suppose to be. What both pdurrant and Harper said suggest this is something to do with the hard drive.

[apprenticeharper]

That it works on a new user account on the same machine means it isn't hardware related.

If you're willing to spend the time needed, I can try to work out what the problem is, but it's likely to take some weeks of back and forth.

To start with, please make sure you've completely removed all Amazon and Kindle folders/files from the usr Library and re-install Kindle for Mac 1.17 and check it's still not working.

[ElleKayEm]

Oops, I was assuming the main Mac and the Mac mini were different machines.

[bookworm17]

I am happy to work with you. I understand that it will take a few weeks of back-and-forth (especially because I travel a lot).

I did the completely remove and re-install on my last attempt (where I got the second user on the same machine to work).

[apprenticeharper]

Great. Let's have a closer look at why the decryption is failing.

I need you to edit kindlekey.py a little, and run it manually in each user account and upload the output here.

The edits needed are at at lines 1458, 1538 and 1539 where you need to remove the # before the print statement. Make sure the print statement is indented the same amount as the statement on the line that follows it.

This will give us the first clues as to why the decryption is failing.

[bookworm17]

I can do this.

Where do I find the kindlekey.py file? Is in ~/Preferences/calibre? ~/Application Support/calibre?

[bookworm17]

I tried the following:

cd ~/Library
find . -name kindlekey.pl

and found nothing.

Note: I'll be traveling the next week, so won't be able to do any follow up until the 8th.

[ElleKayEm]

It's in the DeDRM plugin zip. You could edit it before loading the zip into calibre. Or open calibre and click preferences > miscellaneous > open calibre configuration directory. Then look in the plugins folder for DeDRM.zip.

[bookworm17]

I edited the file and loaded the new .zip file into calibre.

I then loaded the book fresh from Amazon and reloaded into calibre in debug mode.

Of course, it worked this time. In any event, here is the debug trace with the extra printing on.
worked.txt

Again, I won't be back at this machine until next Sunday. So, no response doesn't mean that I've lost interest.

[apprenticeharper]

Well, try again with the original plugin, but I suspect that will work too. At some point that file got recreated, in a format that the tools could handle.

But if it does return, please let me know.

[bookworm17]

I just did a new batch of Kindle books and it's working fine.

sigh

Close thread.

[ElleKayEm]

If you're all set, you can close the issue.

[bookworm17]

Done
