Got kinect last weekend and i can't make it work with my jtag. It asks me to connet to live to download update. I;ve tryied putting it on USB as $systemudpate and $$systemupdate and console doesnt recognize update, so i've tryied update from CD, i've downloaded update for cd from xbox.com, burnt it onto cd, console sees its update disk and if i run it it says that console is already updated. How to apply kinect update to my 14719 jtag?

If you've got updates limited by Dash Launch, the folder name should be $$ystemupdate, not $$systemupdate. Also, check that Dash Launch isn't blocking updates totally.
