I have used wii, firmware version 3.5K with drivekey. Drivekey option setting is not works in Korean firmware even change region to USA. So i have tried downgrade to 3.2U by costom IOS downgrader 1.2. (I know about anyregion changer but it doesn't works to my system. It saids "couldn't find empty IOS slot") cIOS downgrader was work well...download and installing....BUT at last, the firmware installation is failed!!! Then, i restart wii and i can see messages in English and pressed A button. However, the channel menu doesn't show. No more progress, just black screen...I suppose changed menu system to USA but firmware is Korean...mismatched. So...what am i suppose to do? How can i recover it...throw to the trash? Help me please....or any comment me.
