Just a day after the Nintendo 3DS released in the West (Europe & US), a number of Nintendo 3DS gamers have been reportedly experienced with the new handheld games system, we call it "Black Screen of Death". This error occur anytime when the 3DS is started. Nintendo were quick to address the problem plaguing players, with an update now having been released for download in hopes of fixing the bug, which froze and locked gamers out of their gadget!
It seems that firmware update can solve this problem, so anyone else facing BSoD can update the 3DS firmware which can be done under "System Settings" -> "System Update". The download will take several minutes but once it’s done your Nintendo 3DS will be up to date and ready to play!
