then install starfall,
if you dont have internet connection then there's no point going back to how you were before be cause starfall needs 3.2e/u as far as i know there is no way to downgrade with out internet connection.
you can revert back to how you started by formatting the system memory in the settings but make sure you back up your saves to your sd card, or you can use any title deleter to delete ios 249 then your good to go again
