How to restore my iphone 5c to factory settings?

A few months ago my daughter lost her iPhone 5c in the woods. We had it deactivated after that. Just a few days ago, we found it again - someone had found it right away and it was safe and unharmed. We have been trying to reactivate it, but it keeps asking for my daughter's Apple ID and password. She just changed them, but it doesn't want the current ID/password, it wants the old one that she doesn't remember. Is there a way we can reset the phone to its factory settings and wipe out all the old information? I notice there's a tiny pinhole on the side of the phone - can we do it by depressing that? I'd hate to throw away a $300 phone, so we're trying everything we can.

The phone will only take the old username and password. That tiny hole on the right side of the phone is for SIM tray ejection. It won't reset the phone. You can take the phone to Apple if you're the owner of the phone and they'll help you with it. If they refuses, you've to go third party and it will cost you. If Apple refuses, feel free to mail me for this issue.
