How to jailbreak iPhone 5 iOS 6.1.4 or downgrade to iOS 6.1.2?

Hi i'm looking to jailbreak my iPhone5 iOS6.1.4? Have tried with red snow and evasion. Unable to do it. OR Is there way to downgrade it to iOS 6.1.2 and then jailbreak it?

Gudiemyjailbreak.com It is coming out tommorow. It is illegal to jailbreak, the police will catch u find your ip address and you will be arrested. DO NOT DO IT!

There are no jailbreaks for iOS 6.1.4. Anything claiming to be is a scam and should be avoided. Have you ever had iOS 6.1.2? If not you will not be able to downgrade. It is not known if there will be any jailbreaks for iOS7.
