if you ever unlocked bootloader you will not get the update and you will not be able to update manually. even if you lock the bootloader you will never get OTA updates ever again.
but if you want to update you can by doing this.
first flash .raw full ROM (I cant post link to download it but if you Google you might get it). keep that file in your external SD then go to droidboot and do a factory reset from there go back to droidboot and select SD download your phone will automatically flash stock ROM and your phones bootloader will get locked.
then you can update manually.
