Cannot deDRM azw3 file

[fsa317]

Question / bug report

Hi, new to all this. I was able to download an azw3 file from the amazon site under my content. When I try to load it with Calibre and the plugin nothing happens and I see this in the logs. I entered a serial number for a Fire tablet I had that shows up under devices, but that device isn't actually being used.

I also have kindle for mac but cant seem to find any files to mess with from there.

Which version of Calibre are you running?

7.0.10

Which version of the DeDRM plugin are you running?

v10.0.3

If applicable, which version of the Kindle software are you running?

No response

Log output

Won't work with a Fire. If you have an E-ink Kindle, choose that and enter its serial number. Otherwise you could use Kindle Classic for Mac (not the App store version). For that, you would also need to update to DeDRM 10.0.9 and have the KFX Input plugin. https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9 https://www.mobileread.com/forums/showthread.php?t=291290
