I was ecstatic when I heard about LanguageBreak and was able to successfully jailbreak Paperwhite gen 12 (PW5) with ver 15.6.2.1.1 software. I installed mrpi, kual, koreader and other tools available and was learning about my now significantly expanded new features. I installed the jailbreak hot fix and clicked on prevent installing ota on kual. I thought I was safe from upgrade.

Next day I connected to Wi-Fi and was immediately upgraded to 15.6.4 by Amazon. It appears that the jailbreak survived, but clicking on kual does not work (application error: the selected application cannot be started) and re-installing anything with mrpi doesn’t see to work.

Am I doomed? Is it possible to downgrade the version? How?

IF I can downgrade, how should I protect kindle from the upgrade in the future?
