I attempted to JB according to this article below.

https://www.zdnet.com/article/how-to...source-reader/

I used the "Update_jailbreak_0.13.N_dxi_install.bin" for my old Kindle DX with serial starting with B005. It updated and gave the usual .006 error.

I then installed the MKK file (MobileRead Kindlet Kit) according to article. It updated then restarted.

I then installed KUAL to documents as instructed. It failed when I tried to load with a message such as "app not authorized to run on this device" or something like that. I assume because the JB did not work so unsigned non Amazon apps will not load.

Also tried Launchpad per the article but the hotkeys did not work so again I assume the JB did not take.

What did I do wrong? I looked through the steps but couldn't figure it out.

Are there any other methods I should try?
