I believe I need to replace the original TSOP in my xbox. It will not enable the MS Dash to run. When I try to run it, it comes on for a second and then goes to black. I also get an error message saying "your xbox needs to be serviced. I am able to run the EvoX dash and it functions fine. The problem with not having the original MS Dash is when I try backup my games I am not able to play them from the hard drive. Even if I use EvoX, I am still not able to play them. I do have one game that I was able to backup and play before I zapped my original bios. Is my pattern of thinking correct? If so, please help. If not, please help. Your help will be greatly appreciated. Thanks!!!
