Well, then, you're ideally screwed. Unless you can afford a new motherboard or perhaps a NAND Programmer Modchip (Infectus). Check out this thread: http://www.wiihacks.com/bricked-wii-...t-bootmii.html

new motherboards are less than half the price of a new wii on ebay.
If you have a NAND backup, you can recover a Wii that had bootmii as boot2 or as an IOS using a programmer.
If you dont have a NAND backup, you can only recover Wii's that allowed bootmii as boot2 (even if it wasnt installed).
