I play medal of honor / cod mw3 regularly by connecting to the internet through a bridged connection on either my laptop or like now to my desktop PC.
I connect xbox360 wired to PC or Laptop. The laptop or PC is then wireless connected to internet thru BT Openzone / BT Fon / BT Hotspots.
Admittedly this provides a strict or moderate NAT but it's worked fine for weeks. This set-up also works even without entering any BT log in details/ (username and password provided when subscribing to become a BT broadband Internet user)
I do not have broadband dsl - only connection is wireless.
Came to play COD MW3 last friday for the first time in a while. I normally just play Call of Duty Medal of Honour. Screen message prompted that system update was required before connection to Xbox Live could take place - refusal of this update would prevent connection to Xbox Live.
Attempted to download the suggested update but each and every time regardless if I attempt it via my PC/Xbox or Laptop/Xbox - I get the same error message.
Update Failed. Can't download the update. Status Code: 397F - 0000 - 0080 - 0300 - 8007 - 2F7C
It then rather frustratingly suggests that I check my xbox live connection - stupid considering it was the 'insistence' of this download that prevented me from connecting to xbox live in the first place.
What you've tried:
I have tried downloading the updates to PC as zip files, then unzipped before copying onto either a pen drive or DVD system updates.
Neither of these work as forms of updating as the console doesn't seem to see either of these once I restart the console and try to update.
Pen drive pre-formatted to FAT 32. Folder copied to pen "$systemupdate" but on restart the console just doesn't see it.
CD or DVD on restart the dash board just shows the disc as being of 'mixed content' and fails to read it.
