Can I go back to 5.0?

[RobVeee]

My note 5 had become unless after the 6.0.1 update.  I've done factory default twice still issues. Wifi only works on 5 gig. If I connect to 2.4 at all it constantly disconnects unless I shut down Bluetooth.  Battery discharge is crazy. 5 hours a day max. I've bought the Zerolemon 8500 mha charge case just to get me through most of the day. I need to go back to android 5.0. Does anyone know where I can find an official 5.0 ROM file and how do I roll back?  Thanks.  I'm despite. Next step is to go back to my Note 3.

You cannot officially rollback.
