and for those who dont want to use mobile odin , just flash 4.1.2 firmware with odin , root , use triangle way , unroot, go to recovery ,factory reset and voila your counter is 0 ! and as mentioned in the OP you must have mj5 bootloader or earlier ! Anything above mj5 is knox enabled so it doesnt matter if your binary counter resets to 0 the knox counter would be triggered anyway !
