Help on updating my wii to play Skyward Sword? (:

Well this is my first post on wiihacks...

I was just wondering... I got Skyward Sword last week and haven't been able to play it due to the it needing an update on my softmodded 4.3 wii! (:

So basically I'm asking you friendly people, or is there any way around this disc update, or if I do update, will it brick my wii...

To be honest if all it'll do is remove my softmod, I don't really mind!

I don't use it too often! (:

Hopefully someone can help me! (:

Also: I am quite the noob at this so if you want any information on my wii, please tell me how I can retrieve such information if you don't mind! (:
Thanks in advance! (:

Priiloader is what you need to block the update. There is a guide on this site for that game too. Searching will do wonders.
