How to downgrade from ios 7 beta?

So my little bro thought he found a way to upgrade to ios 7 for free but now it is asking for the development account we do not have one, now we're trying to downgrade and recover but it won't even let us connect it to itunes without trying to get the developer account… What can i do it is an iphone 5

1. Back up your data.
2. After that go to: Settings ---> Reset ---> Erase All Content and Settings
3. Set up your phone as a new iPhone (iTunes won't let you restore it directly from a backup since the iOS versions don't match -- it will restore to whatever version your device shipped with). You can restore your data after that.

If you aren't a developer, then you can't get iOS 7 yet. You can wait like the rest of the world. Nothing makes you special. You don't need an ugly operating system right now.

Make sure your running the most recent version of iTunes and restore your device to factory settings.

Then set up as a NEW PHONE and it will restore to 6.1.4

I had this problem as well. After I had installed iOS7 just because i wanted to use the new OS, i know you're not meant to if you're not a developer blah blah and all that bs but i wanted it so i download it. However i had issues with my phone activating my facetime and iMessage so decided I'll just resetting it and starting it up as a new phone but I then realised this caused more problems than it solved. So basically hold the power and home button simultaneously then release the power button but not the home button (btw you should be connected to iTunes when you perform this) on iTunes it'll come as your mobile is in recovery mode then click restore (make sure you've downloaded iOS6 onto your computer) and then click it and you'll be back on iOS6.
