I took the X360 to a person to get it flashed and he told me there are separate charges for "flashing" and "updating". I wanted to ask how is it possible to "update" a flashed xbox 360? I tried Microsoft's update and it reflashed the X360 back to firmware version. So how is that guy gonna get it "updated" without it getting reflashed to frimware version? What is the procedure for updating an already flashed X360?
