Hello! I have 8555 dash with Iexteme 1.6. I never went on-line or live... I got a new xbox S so I want to copy the games saves to the new xbox... The 8555 doesnt allow to save on usb stick so I want to update to 9199... my Q is: will the update ruin my iextreme 1.6? will I be able to play all of my BACKUPS like on the 8555 dash? Thanks!
