Kinda hard to figure out what is happening with your wii. But nevermind the lack of info. I can tell you this. If you softmod your wii with the softmod any wii guide, it will restore your region free. I think what you are saying is your friend updated to either 4.2 or 4.3 and you lost region free for your WiiKey 2. So after your done with the softmod you will be on 4.1 and your region free will be restored. There is a link to the guide in the spoiler below.
