For some reason i cant get out the gateway mode. What i mean is that i don't need to use the blue card to install the GWA installer again. All i have to do is go to the "Nintendo 3DS Profile" then the system will go black again and allow me to play the 3ds Roms =__= . I have turn off the power several times and it is still like this. This could be good and bad. I will see if the system will be normal after long power off.
