Hello, I have a Wii that had 4.0U with Homebrew and NeoGamma, I decided it wasn't worth it to keep the hack so I used AnyTitleDeletor and deleted whatever was needed to make my wii a "Virgin". I then formatted my Wii and updated to Wii 4.2U
But there is still 2 Weather and 2 News Channels.
What can I do to take it back to factory settings without any of these things or traces of a hack?
Also, what if I leave it as is, can I get hurt by future updates?
