I just upgraded my wii from 3.2 to custom 4.1, then fixing IOS using Pimp my Wii... went to install preloader... locked up and I powered off. Will not boot anymore. Not able to get error codes, etc... just a black screen.

Tried to use Unbrick discs, nope.
Tried to use GC gamepad, nope.
Tried using Wii Fit, Super Mario Galaxy..nope.
Tried to get Preloader to appear with reset button, nope.

Am i screwed? I have Bootmii installed as IOS, I *think* i backed up the NAND (is that the 000000001 file?), and have homebrew and twilight hack installed...

What are my options???
