How to update

Yeyint

I am using iPhone 4 GSM. It is running with iOS 6.0.1. I want to update my iOS to iOS 7.0. But in my phone setting> general> software update, there is a notification to update to iOS 7.1.1. I downloaded the firmware of iOS 7.0 for iPhone 4 GSM from your website and I updated my phone to iOS 7.0 with my iTune. It cannont be updated there was an error message while extracting firmware. The error message is " Firmware file was corrupt. Disconnect and connect try again". I don't understand this error. I try to update for three time but the same error was shown. Please tell me what I should do if you can. I am not a jailbreak user. I am using iTune 11.2 version.

You can't update to iOS 7.0 or any older iOS software updates as Apple has stopped signing the firmware files. You can restore to latest software update only, which is iOS 7.1.1.
