Hello, I'd like to get some help to repair my Wii a little. Since yesterday, booting it caused a black screen,no Bootmii, I just formatted my SD card and put only Bootmii files on it, which apparently loads it. I have a NAND backup of a old system menu, but I'd like to use it only as a last resort. Is there anything I can to do check what causes my Wii to go on a black screen ? Or should I just put that NAND back and start over from it ? Any help would be much appreciated, as I'm not really tech-savvy myself Thanks in advance for your time.
