To put it bluntly, you are SOL. Without the usb port you will not be able to odin the stock tar. Mobile odin may work, but as stated earlier, if you are on MJA or newer than your knox warranty flag is tripped so there is no purpose to reset to stock since there is NO WAY to reset the knox flag. If you have insurance, that is your best option, if not, then send it in to Samsung and they will either fix it or send it back with out fixing it.
