I updated to MK2 as soon as it was offered to me not knowing about KNOX at the time. I have been patiently waiting but I still don't know if a solution is available for me. Has a solution been found to root MK2 without tripping KNOX flag? And will this same process work on whatever the pending update I have on my device now to what I assume is 4.4. We also have a S4 back on the version prior to MK2 which we haven't been forced to update. That one being the more critical need of root.
