I have been trying to hex edit mine too and I got it to work like 2 out of 40 times and yeah, most of the time my Xbox froze too.. I also do not want to give my save to someone else to mod for me. I like to learn how to do things and then do them myself, so if you ever figure out (or anyone reading this) how to hex edit it consistently without the Xbox freezing please pm me or message me on Xbox.
