Patch bypass research.

[ixGAMEOVERxixx]

Hey guys, me and xThunderUKx (New account - x CrONiiC Zz) were doing some research into bypassing the patch and we thought of a new method, here is what we did.

 

____________________________________________

 

First bridge your xbox 360 through your computer - we used Cain and Able.

 

____________________________________________

 

We captured the packets being sent when IDLE (on the dashboard) and we found the following IPs

217.43.229.188

65.55.42.180

 

____________________________________________

 

We then went Call of duty 4 (After we updated) and recorded these IPs

201.131.119.238

87.248.212.83

 

____________________________________________

 

We then went back to the dash removed the patches and went on call of duty 4 and recorded these.

87.248.208.49 <<<< Update server

65.55.42.183 <<<< Update request

 

The first one is the actual updating process (the downloading bit)

The second one - we believe, although it is a xboxlive IP sends and receives data about your call of duty 4 version.

The xbox 360 sent out 3 packets of info to 65.55.42.183 and then the server replied and started the download.

 

____________________________________________

 

We then went in ZoneAlarm Pro and blocked The first IP, The update dialog appeared but would not download anything (stayed at 0%)

We then removed that IP and added the second IP to the blocked list - We remained logged in to XBL and only disconnected when we clicked on XBL, it asked us to sign in again, we were unable until we removed the second IP from the list.

Just to test that the second IP was not related to XBL we went to the dashboard and then played another game and did not disconnect.

____________________________________________

 

The ports used by XBL to connect were

25717

and

3074

The first one seems irelevant as it was detected during the idle part.

The second one only appeared when downloading.

____________________________________________

 

That is all, if you want to have a look for yourself...

 

If you do find anything please send me a Private message or post in comments.

If you are trying to make the game let you play online without the update, it will now work. If you try to connect to someone with the update it will give the error "Your playlist data is different than the host's."

I know this sounds a bit stupid, but im pretty new to modding, and I was thinking of hex editing the files containing the actual map packs, or the full game saved to your harddrive (xbox 360), there are just a couple things I was wondering, do the map pack files actually contain any values that can be changed, and if they do, will it still run or will you get an error message when trying to start the game.

[SotG Caboose]

Map packs are in LIVE container files, they can not be signed.

this would work for WaW too right? and also, id be able to play with my friends too if they also blocked the right IPs. is that how it works?

[jemil12345]

Can someone help me with this plz?

 

if what my aim or msn i will pm it 2 u

[360]

This seems like a lot of work to me but I might try it sometime l8r on idk though anyways good job.

[CMLiedtke]

just an answer to my own question above for anyone wondering the same, I finally decided to just try it, and playing WaW without the updates takes out the menu options for the maps, so no it isnt possible to do this to mod zombies as far as my knowledge of this stuff goes

[CMLiedtke]

not my tut, and havent tested it yet, but i figured people reading this thread would probably find it usefull
