Hi I have a an phat xbox360 premium (20Gd HD), which I bourght a few months ago second hand. All works just fine but when I have tried to install the latest dash board the installation goes about 75% and then just hangs there for about 10 mins. After that it comes up with an error code of 3151-351F-1600-2203-C000-0001. I've tried updating via internet, usb and CD disk and always get the same error. It currently has the 2.0.12625.0 dash board installed. Any help would be greatly appreciated.
