All 319 of my Kindle books are now saved on my NAS and unlocked.
I had to re-add my old Kindle Paperwhite device from 2019 to my account to enable downloads, but once done https://github.com/treetrum/amazon-kindle-bulk-downloader worked great.
Then I installed https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9 into Calibre, configured my Kindle's Serial Number and imported the downloaded files.
One bulk conversion to epub later and everything that I bought the past 15years is now actually mine - just before Amazon locks shit down further on the 26th.
