How to get around authorizing step while setting up an iPhone5C?

My friend gave me her old iPhone5C a few days ago and I've been trying to set it up Example, Language>Country>Set up internet>Apple ID Authorization. I'm stuck on that last step, because the iPhone is still logged on with her Apple ID. She got a new phone awhile ago, so she doesn't use that Apple ID anymore. (I swear I didn't steal the phone or anything lol). My other friend said I can try to put it in DFU mode, (which I'm doing right now) and I can set up the phone like brand new. Its also updating to iOS 9.2 right now.

She will need to wipe it first, then you set it up as yours. There's no way around it.

DFU will do nothing, if that worked then everyone would just go around it.
