What are you doing?
I'm really afraid to help you, but I'll try.........God help us both.
HAVE YOU TRYED THIS????
just change you're IOS in settings from preloader. try to use 60 or 36
If you did and it don't work you can try my way..
This way WILL DELETE PRE-LOADER WITCH MAKES THIS DANGORUS!!!!!!!!!!!!!!!!!!!!!
If there is problem after this there will be no way to fix that Wii..
If you do what I say to a T you should be ok.
Unfortunately I cant garatee anything.
DownLoad this
http://dl.qj.net/Custom-IOS-Downgrader-v1....23517/catid/526
Custom IOS Downgrader v1.2
Next extract it and put it in a folder and call it cIOS Downgrader..
Now rename the cIOS-Downgrader_v1.2 file to boot.dol..
Now place the cIOS Downgrader folder in the apps folder on the SD Card..
Next put the SD Card in the Wii and start up Pre-Loader..
In Pre-Loader select HomeBrew Channel and run cIOS Downgrader..
Find 4.0U "DONT INSTALL ANY OTHER SYSTEM MENU BUT 4.0U" select it to install it..
You did say the Wii was 4.0U right?? IF it was 4.0E than install 4.0E..
DO NOT TURN OF THE POWER DURNING A SYSTEM MENU INSTALL!!!!!!!
!!!!!WARNING!!!!!
This will delete Pre-Loader and can take 30 minutes+ so dont turn off the Wii or you'll have a full brick and NO WAY TO FIX IT!!!
After this is all done PRAY the Wii boots up...
If it dose install Pre-Laoder v29 and you might want to install BootMii and get a NAND back up to help in the next brick you make..
GOOD LUCK!!!!!!!!!!!!!!
