    LewisThomas , Apr 6, 2015 :
    So I was wondering, if I root my phone and install a Cm12 nightly build then when the OTA comes out for Cm12s can I use titanium backup to back up my phone. Then can I go onto manually flash CM12S OTA and not lose the stuff on my phone? Is that how the app works? Thanks.

    Yes, Titanium saves your apps so you can restore them.

    So I will run you through what I want to do.

    1. Unlock bootloader and install TWRP
    2. Flash SuperUser for root.
    3. Install titanium backup and backup everything?
    4. Flash a CM12 nightly build.
    5. Flash OTA (when it comes) and restore EVERYTHING with the titanium backup.

    5. Go to TWRP an reinstall Root
    6. install Titanium and restore everything.
    6. Flash OTA....no other rstore needed (However a good backup is always recommended)

    If you don't wipe your sdcard before flashing the backup won't be deleted.

    How do you do it without wiping the SD card though?

    In twrp go to wipe > advanced wipe > Wipe dalvik cache, system, data and cache
    Do that before flashing your ROM.

    It wipes your system but leaves all the files you have on your sdcard intact.
    From there you will have to flash the new ROM that you'll have placed in your sdcard before. That's how a clean install is done.

    You only need back ups only if you want to save your data inside the apps like your login session open, text messages, chat history on some applications. The pictures, though, will always remain without backup if you just flash from CM12 nightlies to CM12S.

    Oh.. but I'm also thinking if I just root and stay on KitKat for now, will I receive the Lollipop OTA and if I do install it, will I get put in a bootloop?

    Even if you root and stay in KitKat CM11S you'll receive the OTA upgrade. You’ll lose your root access when you install an operating system update. The OTA update sets your Android system partition back to its factory state, removing the su binary.

    In order to prevents you to lose and having to re-flash the custom recovery (TWRP), as well, you need to go to Settings->Developer Options->Update and uncheck CM Recovery.
    After that just flash superSu from custom recovery (TWRP) again.

    Oh so when I flash SuperUser again after I finally get the update, I will keep the update and my files along with root access again?

    Do you have your bootloader unlocked?
