Itīs sounds great. I think it's only a matter of time until this is available for the S5. Suppose Knox is an e Fuse, Samsung will not have the time to dismantle all devices to see if the fuse is really defective, or the Knox counter was emulated.
I own myself an I9505 without Knox counter, but have never had a reason to have to return my phone. Now, I also own a G900F with Knox 0x1 (after flash) and I think if this phone was built just as good as my i9505, then the counter can be no matter to me. Consider, I have my S4 certainly flashed to 100 times.
My phones are sacred to me.
Sorry for my "english".
