Default [Q] Can I recovery data after a factory reset?

I asked this on Reddit a while ago and for some reason I didn't think to ask here on XDA...soooo

I have two N5s. A white I bought on day one and a red one I'm typing this on. I finally completed my data transfer to my red one and figured I'd factory reset my white one to tamper with it. Lo and Behold I realize I didn't save my downloads folder.
Can this be recovered? or at least some data.
yeah...
