Last night I was trying to download my firmware to 4.2 using dop-mii. I had downgraded some IOS subs, I think that is what they are called. I then proceeded to downgrade the firmware version t0 4.0 from NUS servers. It downloaded fine but when I went to apply it came up with an error. Then proceeded to dump the hex to the screen. I then rebooted and all I got was a black screen. I do not have a NAND backup since I could not even load bootmi into boot2 i could only run it from IOS. Since my wii is to new. I also do not currently have a modchip, or even a gamecube controller. I would get a gamecube controller if everyone is confident that could fix this without a modchip. Let me know if anyone has any ideas.
