You don't need to recover it after it is fixed via xplore360 extreme /conflag remover /hash block calculator it will then work recovering profile without fixing means you will lose any gamerscore earned so its pretty pointless playing the game really if you don't intend to fix
You need a lead to connect a mu to pc you could make your own but I would advise against that
Or you could just use a usb stick you may need to update the banned xbox to the newest dash curently on
The Microsoft website http://www.se7ensins.com/forums/topic/9995...anned-xbox-360/
Couple guides there for a mu (well one now didn't know first link wasn't allowed sorry)
Usbxtaf (I think that is the name ) is the program you will need for usb really easy to fix profile takes like five minutes i found it easier to go out and buy a rrod one and fix that cost me 20gbp so ms can ban away if they so choose
As long as they done reset my gamescore I don't much care how many of my 360s they ban not one cost over 50gbp..
