OK, So I called M$ and presented a scenero like "I rent a lot of games and therefore have a lot of game saves, So when I return those games those game saves are no longer valid for me, how do I erase them"
So the rep procedes to tell me how to remove them one by one, so I said what if I get lazy and keep forgetting to delete games, so now I have a lot of them, is there a way to delete them all at once, He said sure, asked me for my serial number and after giving him that he said, NOW THIS IS SPECIFIC TO YOUR XBOX ONLY but...
1. Make sure any disc is out of XBOX
2. Goto main menu (Not the live! menu) and goto Settings
3. When in settings goto System Info
4. When in system Info press Y - UP - Y - A - A
NOTE: for the UP Direction you must use the "Thumbstick"
After doing that I get the "Are you sure?" prompt. He never asked me for a Kernel version or anything else. Just the Serial Number from under my XBOX. However I'd be interested to know if this works with anyone else that has
Kernal # 5838
If you have this Kernal please try this and see if it works on your XBOX
