Hie, I have an iphone v1.1.3 unlocked which is currently not functioning after i updated the iphone to the latest update using the installer in my phone. After few hours, the phone switched off itself and now i cant even reboot it to safe mode. I tried to charge the phone then it came out the wire with itunes image. That is all i can go to. Then it will go off again after i pull the usb out of the charger. Please give some advice as well as guidance. Thank you.
