Screen displays Samsung Galaxy Note II that turns black

Reflashing updated firmware properly .

if itz not fix yet,

Had something similar when I first tried rooting my gn2. Can't recall the exact details, but the guts of it was that I had rooted it and applied an outdated recovery, and got this same behaviour. I panicked a little bit. I was able to get it into download mode, and tried a new root method which restored the factory recovery, which fixed the boot screen and allowed me to access the home screen again. I then proceeded to install a current recovery without incident. Hope that helps, and sorry I can't recall exact details.
