That is about performing the LanguageBreak jailbreak on lower firmware. If your kindle has been jailbroken, you can downgrade to a lower firmware. I've never downgraded, so I don't know if you need to re-jailbreak, so it would be best to downgrade to a firmware that can be broken with WatchThis! or KindleBreak. If that leaves you with a firmware lower than you want, you can upgrade to a suitable later version.

The whole point of a jailbreak is to install the community developer key, which allows community signed packages to be installed, primarily MRPI and KUAL. That opens the door to custom package installation. KUAL extensions don't even need to be signed.

The hotfix enables the jailbreak to survive firmware updates (up or down), but amazon complicated things starting with 5.16 by storing developer keys in a mounted squashfs. I don't know whether the hotfix takes care of the case of downgrading to a version using the old key storage method.
