i got 3004 error while installing ios 7 , how to fix it ?

I was trying to update my iphone 5 to IOS7 and couldnt do it for 5 times then I did the following and was able to update it right away 🙂

Clearing your DNS cache may resolve the issue and enable you to connect to the iTunes Store.

The easiest way to clear your DNS cache is to shut down your computer completely and then restart. If you can't shut down, you can clear your DNS cache manually.

1. Click Start and choose Run.
2. In the dialog that appears, type “cmd” (don’t type the quotes) and click OK.
3. After the DOS prompt (C:\), type “ipconfig /flushdns” (without the quotes) and press Enter. Make sure you enter a single blank space after “ipconfig.”
   Let me know if it solved the issue for you

its not helping. i am still getting the same error 3004

try disabling the firewall

On Saturday I was able to update to ios7. Maybe apples servers were overloaded Wed and Thurs when I tried. Maybe if Apple doesn't want to increase capacity, they should do a staged rollout of iOS. Instead of all devices on the same day, release it for iPhone 5's one day, iPhone 4's another day, iPad 4's another day, etc....

delete your itunes cache and restart your pc 😉
