If you have rooted your phone, and have installed a custom recovery such as CWM Touch, or TWRP and have not modified stock system files such as installing a theme that uses modified system files:

Running the update with CWM Touch installed will cause a soft brick.
Running the update with TWRP however will not cause a soft brick.
Install TWRP, and then run the update. (You don't need to boot into it. running the update will do that for you)
* Un-root your phone through SuperSu app after you have installed TWRP but before you run the update.
SuperSU:
Select >SETTINGS >Full unroot
Once the update completes, your recovery will revert back to the stock recovery.
