How can I delete previous owners apple Id

Settings/General/Rest/Erase All Content and Settings

Then set it up as a new device.

Hi, i have tried this already on my iphone 5 but on the activation page it still asks for previous owners apple id, ihave also done a factory reset?

Then you likely know why it isn't working for you.

Ive done a reset thru itunes 4 times and when i try to set up the phone it still asks for the previous owners information. What can i do?
