For a few months now that error had occurred to me of the fact that 3ds did not light up, but there was only a blue light for a few seconds. Today I tried to "fix" it and finally succeed. The problem was that the SD card it was defective (I talked about it later), I got it wrong with another one. I wanted to understand if it doesn't work if it is because, maybe, it is corrupt or for some other reason. Also if it is possible to understand how to make it work again well, given that it was from 64 gb. Sorry for my ugly English.
