OH SH*T: Black Screen of WII!!!
I had 4.1U I believe, and tried an IOS60 patch to play WAD's off SD card.... well it seems to have not gone over so well. My Wii is broke!
The Wii turns on and I hear the drive start up but I don't even get a black screen, it just stays at the TV's blue screen.. the wii does turn on via wiimote.
I had BootMii installed, but as an IOS I guess because I cant get it running from SD card on boot.. and I dont have preloader/priiloader installed since holding reset button does nothing.
I've got a full bootmii backup, but I guess that's useless....
I cant try the recovery mode with savemiifrii at the moment since I dont have a GC controller .. ive got a wireless one but it doesnt connect to the dongle until after the wii is already on... but would it even matter?
is there anything i can do? will one of those universal unbrick discs work? would the savemii dongle work? the infectus thing? if i tried to send it back to nintendo would they repair it? or not because theyd know i had all this modified stuff on it?
any help at all for me? lol (or not so lol, really )

If you have a nand backup you can use a hardware nand flasher to flash it back into the nand. Infectus can be used for such a purpose.
It is worth a shot if you can handle the soldering yourself
