I know what I'm doing but at the same time I don't know what I'm doing. Ive been trying to fix this issue all night, but It keeps not detecting it. It works when I install Rev17, but I require Rev19. The way I've been installing CiosRev19 is on 249 then based at 37(hopefully that made sense to you). Whenever I load up USB loader GX or WiiFlow(on Ciosrev19), they fail to detect the USB device. The USB device is 100% partitions, and it loads up perfectly fine on WBFS. I can assure you I've used the search function. thank you for your time.
