Yesterday I showed how to downgrade iOS 6.1.3 using redsn0w but I didn’t try it myself. And this method is another way to do it but with Sn0wbreeze.
You can create custom IPSW for iOS 6.1.3 downgrade and enjoy evasi0n untethered jailbreak. The process is buggy sometimes but I tried again and again. I was restarting iTunes several times, I was re-entering DFU several times but finally I proceed with success and went back from iOS 6.1.3 to 6.1.2 thanks to SHSH blobs and created earlier custom firmware.
