So I tried to upgrade to the iOS 7 beta by using torrent and iModZone downloads. I failed and my iPhone is in a locked state where I need to register with the developer program. Is there way to return it to iOS 6?
try this one :)
Kindly refer to Tim Brookes's article at http://www.makeuseof.com/tag/how-to-access-ios-7-beta-and-downgrade-to-ios-6/
Hi, I recently published an article about accessing and downgrading here: http://www.makeuseof.com/tag/how-to-access-ios-7-beta-and-downgrade-to-ios-6/
To downgrade, connect to iTunes, enable DFU mode, Shift/Control+Click "Restore" in iTunes and choose an iOS 6 IPSW for your device. All the instructions are in the article I have linked to above.
I also have a few questions for you:
Did you just download the iOS 7 beta, install and see what would happen? When? Were you able to get the phone to boot at all?
Did you pay money to a developer UDID registration company?
You should be able to downgrade pretty easily using those instructions. Let us know how it goes!
