Did I Completly Unmod My Wii?

Im not even sure if that is even possible to do. A few days ago I hacked my wii using the bannerbomb hack (im on 4.0). It worked perfectly except that I was having problems with the homebrew browser. While trying to fix it, I accidently deleted some files off of my sd card. Rather than risk putting it back in my wii, I just erased everything having to do with homebrew and replaced them with the old saves. The Wii works fine now, but my question is, is there anything left on my wii from the previous homebrew. This is what I did: http://bannerbomb.qoid.us/ with the addition of the homebrew browser.

Everything that Bannerbomb and the Hackmii installer enabled you to install has been saved to your wii, except the Bootmii files. You can just run the Bannerbomb hack again and install Bootmii again to restore these files to your SD card. Then just add your apps to your SD card for your Homebrew Channel and you will be good to go
