Hacking I think I messed up

[og style]

I just updated my wii to 3.4u to remove cioscorp and Now my homebrew channel only gives me a black screen. What do I do? Do i need to rerun the twilight hack?
The Backup loader channel still work. I can play my backup of zelda

 

[KiiWii]

yes, with beta2 of the hack
