Amazon has removed Download & Transfer option

[lkmiller]

Note that a few ebooks can not be downloaded to an eink Kindle. (The Amazon entry for the book will tell you)

This is also true for Kindle for PC.

Hello.
I ran through this page. It seems very feasible (if one uses a dumb PC with Windows like I do, that is), although slightly more time-consuming than the system using older K4PC and DeDRM versions.
My fears would be that 1/ the software doesn't find the encryption keys file correctly and I have to go hunt for it (the method for doing so is not very clearly explained), 2/ its life expectancy is short if Amazon puts their engineering teams on the war path against it.
Did anyone here (probably "early adopters") use this method more than just a couple of times, and if so would they be kind enough to share their thoughts about it for the education and improvement of not technically too gifted with slightly cold feet about it people like me ?
Thanks in advance.

I've used it quite a lot (actually, its earlier version, which requires creating a memory dump file). While relatively time-consuming, I've had no significant issues with it.

You can run this on any PC, if you use virtualisation. It works on an apple silicon mac, you just have to emulate the environment.

If you need to do this a lot, you may want to look into Epubor--it automates the process and eliminates the need for technical knowledge.

Epubor is a commercial product that uses (some on this board would say "steals") the method (and Calibre's conversion pipeline) without attribution, so there is a lot of ill-feeling about it here.

Nonetheless, depending on your views and your needs, you may find it helpful.

A plug-in on Calibre and an eink Kindle (but not most recent models/firmware) is simple and automatic.

Epubor might get your Amazon Account banned.

Is epubor doing something dodgy?

If they use Sats' method, there's no danger of getting your account banned.

The risk is that Amazon changes things so that no longer works and then you've paid for something that no longer works.

Yes, of course there's always that risk.

They did for a while. Maybe not today.

Hello to all.
In case someone is interested, here is an article (in French, sorry) about a developer (Pixelmelt, who has, I saw, a page on Github) who managed to convert an e-book from KFX to EPub by analyzing the file very carefully and transcribing/decoding nearly every single letter - over 1 million operations.
Not much detail, but may be the basis for future deDRMing developments.

The argument over whether Epubor using open source code without crediting the original authors constitutes theft is iffy. That they do not maintain a repository with their open source code violates virtually all of the open source licenses. Not acknowledging the original authors definitely violates the very spirit of open source software where often the only reward the authors get is the egoboo of having their work credited in derivative works.

For me, the latter two items are more than enough reason not to purchase Epubor regardless of any perceived value added by their packaging.

Wow, very interesting. I had no idea that Amazon went to those extents.

Pretty soon your Kindle reader is going to need an 24 core CPU running at 20Ghz with 64Tb of DDR27 high speed RAM to be able to display an Amazon ebook. Not to mention water cooling for all that processing power.
