SM-N920P 6.0.1 Unlock I tried unlocking sm-N920P using octoplus

I tried unlocking sm-N920P using octoplus and it showed successful but phone is not unlocked. Is this because android version is 6.0.1? If it is the reason then is it possible to downgrade?

Also if I attempt to downgrade, is there any chance that I can brick the phone?
