I recently got a new micro SD card and so I thought this time was as good as ever to update my DSi, I downloaded F_core.dat and the newest system file and tried to flash it, but I do not even get a solid light or flashes. Is my cord broken, or is there a way to check if I may have updated it a while ago and do not remember. I am nervous to ever try since my DSi is now 1.4.1U for fear of bricking it or something.
