1. Don't hijack other people's posts.
2. Create a NEW TOPIC in this forum. Include LOTS more details. Such as: What type of chip do you have? What exactly do you mean by "not being able to connect to Live"? Are you getting the modded hardware message, or is it just not connecting?
I think you could think of other things to put in your NEW TOPIC.
DO NOT post your details here. Make a NEW TOPIC.
