Wii Bricked with bootmii installed

This has been racking my brain for days... my little sister was messing around with our wii and she installed the 4.2 menu over the 4.1 menu..now the system menu doesn't load....in bootmii, if i click system menu, the screen goes black..if i click homebrew channel, it goes black... i've been looking for any possible solution. Can anyone shine some light on to my problem?

EDIT: i looked in the info for bootmii and it says

BootMii v0.9
Stub v0.9
Mini v0.9

Console id : 026dff86
SysMenu : unknown boot1b boot2v3
NAND FS usage : 84.2%

thats wat sort of happened to me except my hbc did work :p but my system menu for my wii doesnt :[[

i just need to figure out how to re-install hbc....when i put the boot.dol on my sd card, bootmii won't show it...

if you have a GC controller try cboot2 with wad manager

or

comex nand formatter and re-install your system menu
