i updated my wii form 3.1 to 4.2 but wanted to go back to 3.1 so i tried to restore a nand backup i made. the newest bootmii is installed in boot2 and the simulation before restoring went fine, but now the process hasn´t moved since alsmost an hour and hangs near the end. i also have a newer nand backup from 4.2, but i had a lot of disc error problems with that. i suppose my wii will brick if i restart during nand recovery, but it seems this is my only option. any suggestions on what to do now?
