Heeeello, I am pretty new to this... I am stuck after configuring Luma3DS.. I can access to it by holding down [Select] and power up, however after that it just turn black screen whenever i turn it on. When i tries to remove the sd card and power it up, it instantly shuts down. Trying to access Hourglass by holding [Start] down, but it just turn black screen. What did i do wrong?
