wanna return note 5 within 14 days but can't downgrade from root

i used my upgrade to get the note 5 but I'm not really feeling it, wanna return within my 14 day window. unfortunately i updated to AI06 then rooted, & there doesn't seem to be any devs for this variant, as there's no way i know of to return to complete stock once updated to latest and rooted. no Odin flashables or anything, anyone know of a way to return to stock unrooted from my predicament or any other ideas? any help is much appreciated!!
