Problem with iOS phone

[iMore Question]

Hello.
I have an iPhone 5 and the software is Beta Version.
But when I started using the phone today this afternoon, it suddenly stopped! When I switched it back on, it shows activation error because my phone is not registered to a developer programme. Please suggest ways where I can use my phone again.

The beta software expired. Install the latest version of iOS - 7.0.2

First of all, make sure that you’re running the latest version if iTunes. Then, just put your device in DFU mode and connect it to your computer/iTunes. It will download the latest iOS and install it for you. Good luck.
