Before softmoding wii can i format it and start over again? Thank you
We don't recommend that. Going through our Softmod Any Wii guide will overwrite anything that you may have done with it in the past. So there is no need to format or delete anything first.
If you are asking this question, then I would recommend that you install all "optional" components the guide mentions, just to make sure that if you messed up one of your IOSs that it gets replaced with a good copy (if you have 4.3 already, otherwise, everything is required, anyway).
