Downgrading an iPhone 5 to an unsigned firmware version like iOS 6.1.2 is not possible unless you have previously saved SHSH blobs for that specific device and firmware. The iPhone 5 uses the A6 chip, which lacks a bootrom exploit, meaning Apple must be actively signing the firmware for a standard restore to function. However, if your primary goal is to jailbreak, you do not actually need to downgrade to iOS 6.1.2. You can jailbreak iOS 6.1.3 directly using tools like p0sixspwn. Always ensure you have a full backup of your device before attempting any firmware modifications or jailbreaks.
