I think I did it.
I'm not exactly why it began to work, but...
I took EVERYTHING off my SD card, formatted it to FAT and got these files from this youtube video http://www.youtube.com/watch?v=C79D_wkcAS0
Put it into my Wii, turned it on...and magically it boot to the Wii Menu
Give it a shot, NO IDEA why it worked, but it did. Good luck to you!
Yeah but maybe re-installing HBC will overwrite whatever problem R4 installed. Let me know if you gave/give it a shot; I'll do the same when I get outta work tonight.
My Wii is up and running again! I have the HBC channel again and R4 is gone and I know have R6 on there.
Hell yeah, good work! I'll keep you posted..
Mine continues to have the same symptoms:-( When I turn it on with the freshly formatted card and new files it flashes the 16 wii logos thing and goes black. Womp...
