Hello, I recently decided to upgrade my iPhone 4 running on firmware 4.1 to firmware 4.3.1. jailbroken, of course. Several days after doing so my iPhone stopped charging consistently (Connected then disconnected, connected then disconnected and so on). I then decided to restore my iPhone and see if that solved this issue but while doing so, iTunes told me that restoration had failed. Error messages are usually (9) but occasionally (14). It won't let me restore and I am stuck on the connect to iTunes screen. This iPhone WILL NOT enter DFU mode. Apple has told me to contact a technician. I still have my warranty but it is jailbroken. Can anybody help me out? Thanks, blindfirer.
