Hello there. My dash is on 16202 and i downloaded the 16202 system update from here http://www.homebrew-connection.org/files/xbox/system_updates/ (is this link correct?)
Now, i extract with winrar the file, rename the folder to $$ystemUpdate and put the folder in my FAT32 formated usb stick (4gb).
I turn off xbox, i connect Kinect, i connect the USB stick and switch xbox back on. FSD is my default dash, therefore i press RB to boot to NXE, but when i boot to NXE the only message i get (with a red X circle) is that a system update is required for Kinect, connect to xbox live to download the update etc. and the only option i have is to press OK to close the message and return to NXE.
