Hi guys sorry for My english, i have a problem. I cant install Nsp, error code is 0x001fb402. I have searched but find nothing. the sd and the samsung happens to me only with the nsp that do not have the signatures NCA. the sd is formatted in exfat so it is not a format probe. I don't understand until the other night I was installing everything and now most of the games I can't install them. maybe I have some settings active even if I have not changed anything, can anyone help me?
