Hey! I was downloading Couria tweak from Cydia and then the screen went black. I tried to charge it, but there is battery left since Siri do still work. If I put it in DFU mode it will force me to a full restore and update to iOS 7.1, right? Anyone got an idea on how to fix this? iPhone 5 running iOS 7.0.6 Cheers, iiPwn.
