Hi, I wonder if I am the only one. Sometimes when go to the profile screen and enter the 'Gateway mode' my screen goes grey, then black and then....nothing. Only by pressing the power-off button a few times I can switch off the 3DS. Repeating the above procedure -until now- works fine and my 3DS restart in GW mode. btw: I am on version 4.5 on a European 3DS.
