Been working at this for a couple days. This wii has 4.2U, Bootmii installed as boot2 but never bothered to do a NAND backup I went to launch the shop channel to buy Blaster Master Overdrive and it claimed an update was needed. Without really thinking or paying attention I let it. After it rebooted, black screen. No health screen. I can use Savemiifrii to get to the bootmii recovery menu but can't launch HBC and don't have a nand backup to restore, so that seems like a dead end. From what I understand at this point, I'll need an autoboot-able mod chip to run a wad manager or maybe the universal unbrick disc. This might all be moot cause this wii has system menu 4.2 on it already, in which case I'm well and truly fucked. Anyway, how screwed is this Wii? Can it be fixed by any known means?
