2) re-install KUAL by copying its bin installer (also downloaded from the snapshots thread) to "mrpackages" folder and after disconnecting Kindle from your PC run the installer by typing
;log mrpi into search bar and doing a search.
3) add and start using "renameota" KUAL extension and block future OTA updates from downloading when using WiFi. That blocking option inside KUAL's helper menu doesn't work anymore.
