Default Is my warranty voided?

My phone autoupdated from 4.2.2 to 4.3 while it was rooted with activeroot. Now whenever I turn on my phone, I get the custom lock symbol whenever I reboot and my system status says "custom". However, when I boot into download mode, my knox warranty is still at 0x0. I need to send my phone in for warranty because I just received my replacement.

It says:

Knox Kernel Lock: 0x0
