I used the downgrader from this post:

Thank you if you can show me what I did wrong!

Gods and goddesses, I did make it work finally! It took some finagling and several steps but in the end I succeeded!

Verbose log below:

The trick was to not extract the contents of the downgrader zip file to the extensions folder BUT to the KUAL-add-ons folder. After that it immediately came up in the main KUAL menu.

I tried to downgrade to 5.13.7. because why not dream big but it would not take. Then I tried 5.14.1 and it succeeded immediately. Reapplied the hotfix to get KUAL up and running again, then tried 5.13.7. again because why not... but got the invalid fw file message.

Remembering that someone wrote that they tried twice and it worked the second time for them. Looks like the first time the downgrader sets the scene (version number) and does the actual work the second time around?

And it worked for me too!! BUT! the UI was still the new one, library and all.

Hotfix reapplied, tried 5.13.5. No luck, Kindle only showed a blank screen. Back to 5.13.7 by copying the bin to the root folder, and restarting the Kindle by long press while still on USB.

Now I have a KOA3 on 5.13.7 and that unnecessary home/library page still there. But at least it's not full of ads. That's something

(Hotfix back. Good night for now!)
