Run dop-mii v12, and do a system scan- this should fix the bug 11.4 had.
Edit: being on 4.3 makes this more difficult. What guide did you use to mod the 4.3? You are in a big pickle, I can't think of any way for you to load the app. I am not sure a system format would help, I suspect it would not but you can try.
Did you install a patched ios80?
Try to copy your HBC to the sd-card and load it from the sd-card- big useless shot in the dark, but you may as-well try.
