Upgrading from 6.1.4 to 7.0.4 Problems

Hey all, I have been trying to update from my jailbroken iOS 6.1.4 to 7.0.4 and use the jailbreak,
I have tried to use iTunes to back it up (which did not work), and then restore through DFU mode and on.
Neither have worked. I have tried to use TinyUmbrella which got rid of the 3194 Error I was receiving, but I received error 11. Which then I uninstalled the latest iTunes and have installed 11.1.11 and now I get error 3004.
I have checked the hosts file, and there is no apple address in there. What could I do to upgrade from 6.1.4 to 7.0.4?
