I need help!
I have a problem, I did a downgrade to iOS 7.1.2 on iOS 6.1.3 and after that the phone does not recognize the SIM card, writes <NO SERVICE> that this has to do with what is the 4G card?
When iTunes tried to boot up the system on iOS 7.1.2, it made me blame and, of course, as every blind person did not do a back up on my computer, I guess this problem happens because the phone is a jailbreak.
How do I do an unjailbreak, or in any way to raise iOS to 7.1.2?
thanks in advance!

Hello, if you downgrade iPhone 4 to iOS 6.1.3, your device would have no service.
After your restore to iOS 7.1.2 on 3uTools, your device is not jailbroken.
