semi brick wii? need help to fix. i am new
2 months ago I had a person soft mod my wii (red wii) and install homebrew boomii and prii (I think that their names) through letterbomb. I jus discovered now I can not access he wii settings. the screen just goes black an I need to kill power to the wii to get it working again. it appears it is a semi brick? it seems due to the fact the person who modded my wii loaded custom themes. I don't think I have a NAND backup or I don't know where to find it. can anyone help me fix my issue? I may need to redo the whole modding? how do I redo it and erase all previous modding off my wii? how can I find my mac number if I cant access the wii settings?
