I rooted my N9005 and tipped knox counter after a few months of usage (I thought my phone had no h/w problems so I rooted it)
Last week, my N3 flash (camera) won't light up. i think it is disconnected or maybe it was faulty from the purchase date (never used it before).
I flashed back stock rom. Same problem persisted so I went to service center, they refused to help me stating that my KNOX counter is tipped
I am thinking of rendering my phone useless, so they would not see KNOX counter?
