So I've tried using every wup installer I can find, I've tried installing to both nand and usb, and I've done a full check of my sd card but nothing works and I keep getting install error code 0xFFFCFFBF.. It makes no sense because if I persist (and I mean this could take hours to days) I can maybe get some to install finally and they seem to work just fine when they do but this error is killing me.
