I usually download everything as epub too, but I've tried the obok plugin just to know that it can be done. It's easy enough to remove the kepub bits with the Modify Epub plugin.

Ah, that's why I wasn't understanding this exchange.

My K4BNT started refusing to download books today, instead telling me: "Your download was not successful. Please try again."

By coincidence, I purchased a few books yesterday, which downloaded and DeDRMed just fine, but a new book purchased today won't download.

As a test, I removed the new books I downloaded yesterday and tried re-downloading them, but today they won't download. I tested a variety of books including very old ones, and ones I think were .mobi only, and those also won't download.

In the past when my K4BNT balked at downloading, I restarted it, and that did the trick. Today, restarting (3 times) did nothing.

Is it just me, or has Amazon finally pulled the plug on downloads to K4BNT (firmware 4.1.4) and possibly other older, pre-KFX Kindles?

Fwiw, my 8th gen Oasis running firmware 5.8.11 (I've blocked software updates) can still download books, and the KFX can be decrypted.

ETA: I did more experimenting and discovered that I am still able to "deliver" books to my K4BNT by going to Amazon's website and going through Content Library > Books > Deliver or remove from device. Then when I go to my K4BNT and sync, the book will be delivered, though I had to restart it one more time.

However, if I navigate to the book on my K4BNT itself (Archived library) and click on it, it will not download. Instead, I still get the "Your download was not successful. Please try again" error.

Both of my K4NTs (black and gray) still download books. So it's either a temporary glitch, or Amazon is disabling old Kindles gradually.

Thanks. I will continue to monitor then.

I just downloaded 5 "freebies" to my black K5/K4NT? on 4.1.4. But I do worry about the gradual roll out thing...

To be honest, this doesn't feel so much like Amazon deliberately pulling the plug on older Kindles as much as it feels like deprecated software being broken by new processes and not being fixed because the deprecated software is ... well ... deprecated.

Hmm. I was able to download from Archives on both of my K4NTs. So whatever the change is, it seems to be gradual, i.e. hasn't reached my devices yet.

It's certainly possible this is a glitch for me that will work itself out. Who knows?!
