I have fixed the problem using what I assume is not to be mentioned. I assume that it's not to be mentioned since it isn't in the wiki. As for the rest of your questions... I was not able to boot into HBC, both options gave me black screens. After booting via the forbidden tool, I updated the HBC and then I used the system update, which allowed me to boot normally once again. Thaby parineum - FixMii
Long story short, while updating the sysmenu with wadmanager there was an error. Now, after I get past bootmii I get a black screen. I don't have a nand backup as there was some problems making one before (turned out to be my sd card, probably the cause for the corrupted sysmenu wad as well). I can now make one, which is not usefull, but I can also restore. My brother has a wii he bought atby parineum - FixMii
