So thought to unjailbreake, downgrade to 5.8.5.0.2, jailbreak and install that source https://github.com/AthameBook/kindle...-5.8.5.0.2.bin

The message is correct.
Packages are model locked and you are not trying to install it on the Oasis model.
That can be seen in the name of the file.

Try the correct file:
https://github.com/AthameBook/kindle...ce228b1dc87132

You would not have to un-jailbreak to repeat the process.

Important Notes:
That is not a source file, it is a perl binary.

It is not released by Mobileread, and we do not support other people's code here. Get your support from the author.

We do not support or condone "closed source" add-ins here.

I do still support the jail break procedure that I posted (this one).

But additions and changes that you make yourself or get from another site -
NMP, NMJ, you and the author are on your own.
