Please pardon my ignorance, guys, but I just spent another 15 minutes googling around and still can't seem to locate the KToonsez AOSP kernel for my I337.The rom isn't loki-patched because it was made for the I9505 variant. You need to flash Kt's kernel (AOSP version) after flashing RootBox.

Perhaps such a link belongs in the AOSP / instructions since they seem to be specific to this phone?
Edit: Ah, of course I find it in the very next moment. http://forum.xda-developers.com/showthread.php?t=2292341
