Hi, I am adding this here because this post strangely comes up top in search results from bing/duckduckgo.
I had this problem too with my Wifi Kindle Keyboard, but the same process needed to be done. But I was still on 3.4 and tried all the files and got similar outputs to yours.

You have to pull up the firmware version all the way to 3.4.3 for the currently available jailbreak (0.13N) to install - the rest of the older jailbreak files can be ignored.

The last firmware upgrade file available (upgrade 3.4.2 to 3.4.3) from Amazon is here: https://www.amazon.com/gp/help/custo...MQC26VQQMM8XSW

The older firmware upgrade files from Amazon are here https://www.amazon.com/gp/help/custo...3VVAQS4DYDE5KE

I think the rest of the available software add-ons that were in the legacy post should be installed using KUAL instead of separately. There is an updated DevCerts bin file (to get KUAL working) buried in the thread that will need to found because the original one expired.

Now that Amazon is cutting off support for the older kindles I'll get these Kindle Keyboard firmware files uploaded to archive.org eventually.
