    I think of rooting my phone, not to install CM, but just to delete some junk like Google+, Bloatware in general, and for installing XPosed Framework and use some root apps for privacy protection, like AFWall+. That means I want to do most of the things everybody do, except change the firmware, since I like some of the Sony apps.
    The questions are:
    1. Do I need to unlock the boot partition in order to do that?
    2. Is there anything, beside installing a personalized firmware, that can only be done after unlocking the boot partition?
    3. If I accept OTA updates from Sony, will I have to re-root the phone again?
    4. If I unlock the boot but keep sony original firmware, will I risk my phone in accepting OTA updates?
    5. I’ve read about limitations in rooting and/or unlocking the boot according to the firmware version: I got an Xperia Z Ultra: should I update it to kit kat before or after rooting? Same question for unlocking.
