I updated to 4.2 and was proceeding to softmod. I've always used a 2 gb Sandisk micro SD with an SD adapter and have softmodded my wii. I update to 4.2 and proceed to clean out the Nintend0 junk. Jam the card in the Wii and now I get the error, "The device inserted into the SD card slot cannot be used." The SD adapter write protection is unlocked. I've reformatted several times to FAT 32. I have a 1 gb SD card that reads fine but I don't have a way to stick it in my computer. Usually use microSD-->USB adapter.
