Thanks jakibaki for your instructions! One additional question: If I installed the community build, performed these countermeasures: devel-su mkdir ~/oem mount /dev/disk/by-partlabel/oem ~/oem rm -rf ~/oem/* cp -ar /system/vendor/* ~/oem umount ~/oem rmdir ~/oem then do I still have to use emma to return to the latest Android for XperiaX or can I just flash official downloaded SailfishX over the community build?
