Accidently erased all data on my Note 2 Phone, possible to restore?

So as the title states, i accidently erased all the stuff on my note 2 phone. is there a way to restore all the stuff? i mean i don't remember ever somehow backing the stuff up, but i tried to sync it, not sure what that does though.

If you resync it with your google account it should work, dunno what stuff will be restored. Also why do you atill have a note 2

What makes you think its a Samsung Note 2?

It could be a Xiaomi Mi Note 2, that released in 2015.

@GTR12: oh i didn't know Xiaomi named any phones note 2
