I have a wii version 4.3u. I have this version because i was told some years ago to not update because it would not run usb loader gx. I want to know if i can update now using internet. My cios is 249 rev 20. I was thinking about change my unlock from usb loader gx to wii flow/usb-cfg or post loader if they load the games faster and have the possibility of go back to the menu with the games loaded without having to restart my wii, like its today using usb loader gx. i tryed to even change my hdd usb cable but the games keep freezing or loading slower. i hope anyone can help me.
