Hi everyone, I'm trying to update from 5.0.1 to 6.1.2 on my iPhone 4S, which is currently jailbroken. I'm using a 2008 black Macbook still running 10.5, however whenever I try to update to 6.1.2 using a .ipsw file of the firmware I downloaded, I keep getting an error 3194 message and the update fails. I tried following these steps (http://osxdaily.com/2011/11/03/fix-...sted-build-error-in-itunes-when-updating-ios/) to no avail. Does anyone know what could be wrong and how to fix it and update as I planned to? Thanks in advance!
