What did you do to correct the unresponsive touch screen?
Thank you so much for the help, I now have a mobile phone again instead of a car phone. Quick question though, I begin to experience an intermittently unresponsive touchscreen afterwards that is now now responding at all. I am unsure if the two are related but after chatting with folks, I was advised that perhaps something I did during the battery replacement is responsible. I have checked the digitalized cable connection and DFU mode. Do you have any advice?
