Updated my iphone 5 to ios 8 and now i'm locked out?

I need to register my UDID or i'm locked out of my phone forever, someone please help me!

You need to have your UDID added to a dev account. Http://ios5activations.com/ can do that for you in a few minutes. Once activated the phone will immediately start to work again.

You just need to register your device's UDID with a developer account through a site like http://www.udid.in/. It's $5, and then your phone should work again.

Unfortunately that is what happens when you don't activate your UDID. Its very important to get an iOS 8 UDID activation if you want to use the iOS 8 beta, keep that in mind next year when you want to use iOS 9 beta. Just get your UDID activated or restore back to iOS 7 using DFU mode and you won't have an issue

So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!

  • IPhone 3GS Jailbroken, then updated, and now not working I bought a jailbroken iPhone 3GS and then I made the mistake of updating it to iOS 6.It's now stuck on the activation screen. I spoke to someone and they said that once iOS 6 jailbreak comes out it will work again, are they right?
