Hey guys what's up. So I read through this whole thread first. I have an L710 through Virgin and took the 4.3 OTA. Since then I've rooted and flashed CM11 and its working great for me. Here is the dilemma: I downloaded and installed Triangle Away 1.26 tonight, installed it, and ran it. It was showing my counter as 1 and it cleared my counter back to 0. I think the MK5 update has the Knox counter in the bootloader and another system counter. I'll check by going going to download mode here in a sec but thought I'd at least let you guys know.
EDIT: I just shut off an booted into download mode, my warranty counter still says 1 even after using Triangle away. So I'm thinking the MK5 has a flash counter and Knox counter. That sucks for us LOL. Just trying to be helpful. Hope someone finds this info useful.
