well...my wii is still 3.2J and I use wii loader GTX to boot my games. Before updating the darn cIOS38 rev19 Installer...Everything worked fine and no problem. However, after dating it. The base is IOS61-64-v5661.wad. Then the darn will began not to recognize my USB flash drive. Note: After I have successfully installed my IOS and the message popped up successfully installed and then asked me to press any button to restart, when I pressed the button, the wii just froze. I only use 1gb kingston SD card.
