This was on digg, so most probably saw it, but I just wanted to post it here as a warning for those who don't use digg.
Reader Will writes to warn us that updating your Wii quasi-bricks some of the consoles.
After updating his system, every time the Wii tries to connect to WiiConnect24 he gets Error Code: 110213. After doing a little research he found that means he needs to call Nintendo.
"... so I call them up and I speak to Michael or Dan(Can't remember at this point) and after reading the message to him he says I have a hardware error and will have to be sent a new console...so I'm done with my Wii for a couple days as I can't transfer the saves from Zelda anymore...the new Wii is on the way but will take 3-4 business days...
