i have a buddy that has an N2 and i made a copy of my discs that i ordered on the internet for my n2 so i used the same disc as i used on my n2 to do the update and on his it went through the whole update and then it said update complete and it restarted except when it restarted it said please insert appropriate disc again. now it is stuck on that screen and you cant use anything but the ipod adapter and the radio because the screen is stuck on that screen that says please insert appropriate disc. if anyone has ever had or heard of this problem please give me some advice. thank you very much
