To play on xbl, it MUST be from a stock state. NO exploit can be running at all. even though it uses the shadowc function, xbl scans the xboxs memory, and it will find the exploit loaded in memory. that is why that you MUST uninstall ANY softmod to go on live. You can "cold boot" from a game disk to go on live, but some say it works, others say they got banned from this. the choice is yours to try.
as for 007......lol, yea, there are some wording issues that need to be takin care of. what version of 007 are you using? I thought I found them all and fixed them in the latest, but I could be wrong. also, for the default dash after install, the reason why I did it this route is because it is your xbox, you can use what ever skin you wish. Thanks to jcupp114, a custom skin was made for this installer, and intended solely for that use.
and, yes, I changed it so that if you installed, un-installed and then re-installed, your apps and stuff will still be there (except for the dash). this is so you dont have to go through and re-install everything after you un-installed to play on live, hide the fact that its modded from your parents, ect.
