For the above post; there is a .zip to remove knox on the note 3. My wife has a 3 and never had issues rooting or with knox. Hot spot works perfect too. Now about 4 root. Yes, patience is in order for me. In the past, new phones have been given to some tech writers and others tech related. Of course, rooting would be worked on and ready prior, or at least perfected, but I digress. mskip creates toolkits for various android phones and tablets which I highly recommend. I have used his s4, note 2 and note 8 kits with no problems. The kit comes with tons of options. I emailed him about the 4 and he will be making a toolkit for at least the sprint version. His server is skipsoft.net and he may mirror it to goo.im. keep an eye out for it.
