Um thats one thing you dont do is downgrade your wii from 4.2 to 4.1 and then upgrade again. There was someone here yesterday that did the EXACT same thing as you did and had the same exact results. Good thing that you have bootmii installed BUT you never did a nand backup. You would need to run bootmiis menu and go to HBC that way. Youll have to search on this site and get the system menu wad.
