Hi Tonyii,That was no accident, 4.1 is a better stable version for hacking, My opinion only. I always downgrade to 4.1. the higher versions are N's attempt at stopping us modding consoles. If you upgrade to 4.2 4.3 it installs stubs. where we want to put our custom ios. You are very lucky not to be looking at a paperweight. Never unplug during a system install. there is always help on this site. follow the guide, it is tried and tested. at least 60 times by me alone. You should not be messing with ios under 200, these are the system files. If you look at the many posts on here you can learn what to expect your system check to look like. read read read and read again before you get your fingers burned.
enjoy your wii :::
There you are my hero has spoken. Mauifrogs explanation should be enough to say don't mess willy nilly. You will kill your Wii.
