I connected my iPhone to iTunes to restore it, because it is in DFU-mode, but it  keeps saying it wasn't eliglible for this build. Does anybody know what to do? Already followed the steps in apples guide at least a hundred times.
I already know how to leave DFU-mode with tinyumbrella, but my intenition is to restore my iPhone in order to remove the sim-lock (legally, already got confirmation from provider, but still have to unlock via itunes).
thank you

iPhone 4, iOS 6.0.1

    Tinyumbrella probably modified the hosts file on your computer, try putting the file back to how it was before you installed Tinyumbrella.


    See this Apple doc for more info -> iOS: Resolving update and restore alert messages

    If you have installed software to perform unauthorized modifications to your iOS device,   that software may have redirected connections to the update server ( within the Hosts file.   You may receive an error 1004, 1013, 3194, or "This device is not eligible for the requested build" in this circumstance. First, uninstall the unauthorized modification software. Then follow the steps to edit the Hosts file and allow iTunes to communicate with the update server in the Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store section of iTunes: Advanced iTunes Store troubleshooting.
