I've done jailbreak in iOS 8.4 and then I used it and today I've decided to take it off. I've tried the Cydia Impact but it was showing an error message. So I've tried to restore my phone to the stock version through the own iPhone. Then it worked, one thing I wasn't able to do was connect my phone to the iTunes, when I made it I could. But the iPhone was stuck in the blank screen, where it has the black logo of apple. Then I've forced turn off of my cellphone and tried to turn on. Same shit. Now I can't connect my phone to iTunes and it does the same thing everytime, I can't do nothing. Now I've tried to do turn on in DFU mode and used iTunes to update the cellphone and restore it. What happened? What should I do? Things messed up? I broke my phone? please help. iPhone 5s - 8.4 Jailbroken
