Kindle: Oasis

DeDRM: 7.2.1

I'm having the same issue on my Mac. I was able to successfully bring in one book for some reason with the DRM removed. When I try and convert another one, I get an error saying that the DRM is in place and cannot be converted. I tried to convert again using the de-bug option and this is what was saved to the folder after I ran the report and I don't even know if this is normal or if this is just the intro but

This debug folder contains snapshots of the e-book as it passes through the various stages of conversion. The stages are:

1. input - This is the result of running the input plugin on the source
file. Use this folder to debug the input plugin.

2. parsed - This is the result of preprocessing and parsing the output of
the input plugin. Note that for some input plugins this will be identical to
the input sub-folder. Use this folder to debug structure detection,
etc.

3. structure - This corresponds to the stage in the pipeline when structure
detection has run, but before the CSS is flattened. Use this folder to
debug the CSS flattening, font size conversion, etc.

4. processed - This corresponds to the e-book as it is passed to the output
plugin. Use this folder to debug the output plugin.

I didn't get anything else from the debug report.

@phurious You're getting KFX format which unless you download it with an earlier version of the Kindle app can't be decrypted. Since you have an Oasis, you could get the older format by using the "download & transfer via usb" option on your content and devices page at Amazon. Choose the Oasis for the device. Enter your Oasis serial number into DeDRM's customization.

See details and other methods of avoiding or dealing with KFX format here: https://www.mobileread.com/forums/showthread.php?t=283371
