I love how you called yourself "3DSHackerKing" only to ask what a Sysnand is
Seriously dude, we need your firmware version and model, if you want to know your firmware, go to system settings, on the upper screen, in the east low corner there are numbers written on it, those numbers indicate your firmware, a Firmware is, quoting from Wikipedia "
firmware is a type of
software that provides control, monitoring and data manipulation of engineered products and systems", the 3DS firmware is known to be classified in certain numbers, like 4.1.0 or 5.1.0, it depends.
Also, we need the model too, certain models are different to hack than others, for example, a New 3DS XL is different from an O3DS, which methods to hack vary between the systems, but as i said, go to System Settings and check everything that exists on the screen above the "Touch" screen or low screen, to put easy.
