iPhone 4 iOS 7 Update Crashes 75% Through Loading Bar

Hello,

This issue is very, very frustrating .For the past several hours I have been trying to update this device. First off, when trying to update it gave me the 3014 error. I know what that means. It means I've tried to hack into the phone, which I have not. Eventually I progressed passed that part after taking the phone of the USB chord about a million times, it got to the verifying update bar in iTunes and gave me the 3014 error. After that, the phone became useless. It now just displays the 'Connect to iTunes' graphic. I do that and half the time it just tells me it can't connect to the update server. Finally, I managed to get it passed the verifying part and into the install part. It gets to about 75% and just hangs and gives me the 3014 error again. I had no choice but unplug the phone. It's really a guessing game to see whether I will get passed certain parts to update the phone. Really not happy with this service. Disappointed to say the least. And please, do not direct me to restore pages and other Apple made support pages. I've done all that reading and it hasn't helped a bit.
