Downgrade from OF5 to OB7?

Hi guys,

i just recently went back to the note. I just bought the Note 4. I didnt realize how many roms are available for OB7. I updated it to OF5 before I seen the rom selection.

Is there anyway to downgrade from 5.0.1 OF5 to 5.0.1 OB7?
I do NOT want to downgrade to KK or any other build other than OB7.


Thanks guys!
