Hi, I have been trying to mod Halo 2 on Xbox 360 using XSATA. I need to know exactly what to do to get it to work. I have been reading through some threads, and I have done what they said, but I still can't get it to work. I made a patch using serenity, and patched the map, I resigned it using CMR V2. Every time I try to sign in to a profile (not xbox live), it says one of the map files is corrupt and I need to download them again. I can't download them again because when I try to sign in to xbox live, it can't connect. Is there any way to get the maps to work without downloading them again?
