Restore iPhone 4S from iOS 7 back to factory.

[bigpoppamac31]

When I try to restore my iPhone back to factory settings through iTunes it won't let me. It gives me a pop up that says there is a problem downloading the software. I'm on an "illegal" version of iOS 7 beta 6. How can I restore my phone? There doesn't seem to be an option in iOS 7 to "restore to factory".

Look up "DFU mode" and then iTunes will download the licensed version of 7.
