If you have never saved SHSH blobs for iOS 5 on this iPhone 4s before 2013, you cannot downgrade to iOS 5 using normal tethered methods. However, there is still one loophole: Tethered downgrade using a custom IPSW (explained in Method 2).
You cannot officially downgrade an iPhone 4s to iOS 5 because Apple has stopped "signing" that firmware, which is required for a standard restore through iTunes.
However, the iPhone 4s is unique because it can be downgraded to iOS 6.1.3 relatively easily, as Apple continues to sign that specific version for this device to facilitate OTA updates. Methods for Older Firmware
While a direct downgrade to iOS 5 is difficult and generally requires saved SHSH blobs from when that version was current, there are community-developed tools for "tethered" or "un-tethered" downgrades:
iOS 6.1.3 Downgrade (Recommended): Most users prefer this because it is signed and provides the "classic" iOS feel. Tools like 3uTools can automate this process after a jailbreak.
Legacy iOS Kit: This is a popular script-based tool used by the Legacy Jailbreak community to downgrade older devices. It may allow for iOS 5 installation if you have specific hardware/software configurations.
Deca5 / CoolBooter: These tools allow you to "dual boot" or bypass signing checks, but they are technical and may result in a "tethered" boot (meaning you need a computer to turn the phone on if it dies).
Data Loss: Any downgrade requires a complete wipe of the device.
App Compatibility: Almost no modern apps will work on iOS 5 or 6; these versions are primarily for nostalgia or basic tasks.
Security: These older versions lack modern security patches.
