Failed to deDRM a KFX book from Kindle #519

Closed vhosouza closed 3 months ago

vhosouza commented 3 months ago

Question / bug report

I received the Kindle files from a friend (both xxx.kfx and the xxx.sdr). I imported it to Calibre with both plugins installed KFX Input and DeDRM_tools. However, when I try to convert it is not being able to deDRM the file. What am I doing wrong? From the log it seems that it doesn't find the voucher, but there is a voucher file inside the xxx.sdr directory.

Thanks a lot for the support.

Which version of Calibre are you running?

6.29

Which version of the DeDRM plugin are you running?

v10.0.9

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

No response

Were those files from an E-ink Kindle (not a Fire)? If so, you need to enter the Kindle's serial number into DeDRM's customization.

vhosouza commented 3 months ago

@ElleKayEm thanks for the super fast solution. Adding the serial number sovled the issue.
