Have iPhone 4 with iOS 5.1.1
Trying to update to 6.1.2 (not the latest) via downloaded IPSW but unfortunately getting error:
iphone could not be restored device isn't eligible for the requested build
After searching for fix all over the internet found some suggestion like putting # in hosts file in line gs.apple.com but not helped.
Have you any idea why I'm getting this error and can't restore iphone?
