I have a softmodded wii. After I turn it on I no longer get the health screen to press A, just the wii menu. ALso when I boot a game I can play for a few minutes and the wii randomly powers itself down. I am at system 4.1U- I followed a while ago Larryjlite guide recently updating to ModMii. I have checked the power cord, moved the wii to another location and plug outlet in my house thinking that could be the problem but it continues to occur. I have priiloader and bootmii as boot 2. Unfortunately my original NAND backup is gone but I do have one from a week ago but this problem was occuring then so I am not sure how good that NAND backup will be. Can I upgrade to system 4.2 and still use bootmii as boot 2? How would I upgrade to 4.2 and get a clean NAND Backup? Is there a game I can buy to do that?? What could be causing this problem?
