I have an iPhone 4 running iOS 5.1.1 and want to upgrade to iOS 6.1.2 rather than iOS 7.0.4 to avoid performance issues. How can I install iOS 6.1.2 now that it is no longer being signed by Apple?

Upgrading to a specific firmware version like iOS 6.1.2 after Apple has stopped signing it is only possible if you have saved the SHSH blobs for that specific device and version. When you try to restore via iTunes without these blobs, you will receive error 3194 because the Apple servers refuse to authorize the installation. Since the iPhone 4 is a legacy device with a bootrom exploit, you can use tools like iFaith to create a signed IPSW file if you have your blobs. If you never saved your blobs while iOS 6.1.2 was the current version, you cannot upgrade to it and will be forced to install the latest compatible version for the iPhone 4, which is iOS 7.1.2.

If you have your SHSH blobs saved locally or backed up using a tool like TinyUmbrella, you may be able to upgrade to iOS 6.1.2. Without these blobs, the 3194 error occurs because Apple is no longer signing that firmware. Please be aware that many iOS 6.x blobs saved to Cydia servers during a specific timeframe were later found to be broken.
