If it's someone else's, load the dumper with an exploit, not the homebrew channel. If I didn't know what it did I'd be fairly cross if someone put things on my Wii (especially if they'd put on bootmii as well as the homebrew channel, as I disapprove of changing things, but am fine with adding things).
