Hello, when you downgrade to 6.1.3 from 7.1.2, your device will have no service. Because when you flash with 3uTools, it skipped the activation step. And if you upgrade back to 7.1.2, your iPhone will become normal.

I think the biggest problem is that the phone is a jailbreak and that's why it will not return the system to iOS 7.1.2, and when i try to get it back over iTunes to somewhere and stop the boot up and as a mistake tells me an unknown reason.
How can I remove the jailbreak from the phone, can somebody help me?

When you downgrade your iPhone 4 to iOS 6.1.3 following this: http://www.3u.com/tutorial/articles/82/ ... thout-shsh, it would skip the activation step. So your device may have no service. When you upgrade back to iOS 7.1.2, your device would become normal.
