[Q] Wicked Sensations ROM & System Update
I have had my Sprint Galaxy S III on Wicked Sensations for approximately two weeks and must say that I love the ROM, minus the issues with the Kuban Updater -- frustrating because I want to tweak and customized my phone further, which is part of the reason I switched to this ROM. Anyhow, as of today I have been getting, I assume, system update notifications on my phone where it wants me to update to Android 4.3. Question: I am assuming this is not a Wicked update? Next, since it is apparent that it is some kind of stock system update (non-custom ROM update), I should not "update" my phone? Lastly, I thought that system updates and such were not possible on a custom ROM, which leads me to believe that this is some sort of bug with the ROM? Because prior to Wicked Sensations, I primarily used CyanogenMod as my daily driver and on rare occasion a few other ROMs. Any help in this matter would be much appreciated.
Oh, two more things: If this is a stock system update, how can I block it? Second, if I update this what will happen (e.g., will I soft brick my phone or worse)?
Thanks in advance.
