WinterBreak only works on registered Kindles, and changes in the firmware starting with version 5.17.1 kill the jailbreak persistence, so AFAIK it is not possible to have an unregistered and jailbroken kindle on 5.17.1 or later.
I would suggest that you either stay on 5.14.2 or update to 5.16.2.1.1 at most, as things get complicated after this version.
