my experience with a recovered 360 is even after loading your profile sucessfully..
many problems arise..

previously xblive games that i purchase with different account can only be played by the person who buys it..
and this person can only play it when he connect ONLINE.. offline mode it doesn;t work..
this also applies to downloaded media..
previously xboxlive offers some game free for download..
now its not there anymore u have to purchase them again..
