originally i homebrewed my Wii to make backups of my games. My problem was that i couldn't get any of the ISO dumper apps to work. i did a bunch of installations and rev stuff (stuff i don't understand at ALL) but in the end, i would brick my wii whenever i tried any ISO dumper. so i would unplug my wii then plug it in and restart it. after a while i got frustrated and just wanted to start over. i thought i could re-homebrew my wii if i just wipe it clean and start over...thus i reformatted it. now the screen freezes when i use smash-stack. btw I am on version 4.3. how do i homebrew it? and once i do that, how can i get the ISODumpers to work?! tyvm for the help!
You will need to do a complete mod, not just install homebrew. You can use any usb loader to dump/copy original games. Look here for your guide.
