So. Before I flash. I got A few questions. Since I haven't updated my Xbox for a few months (I on the firmware where they won't let me play CoD MW2 and BO)and i'm still at iXtreme LT. So here are the questions: 1.Will I update my Xbox before I flash? 2.Do I have to update my Xbox before I flash? 3.Anything new that will cause restrictions after I update my Xbox from the Xbox site before I flash it? I'm going to flash my Xbox to an Electronics store and they don't come in cheap, and I don't want to waste any money. So guys. I need your help. Thanks.
