Quoted from hank527:How do I update the code is this a full update 6 GB plus?
No, this is not a full update.
Download the Zip, extract the "woz_update" folder to the root of your flash drive.
Start up your WOZ and go into the service menus. Attach your flash drive, go into Utilities and select USB Update. It takes about a minute as this is a fairly large update.
