I would try disconnecting the screen and cameras and see if iTunes recognises it as it could be a faulty part causing it. But I would say the phone has developed a short since the replacement battery should have booted the phone. You will need a multimeter and board view software to diagnose which line has failed. I would start with PP_VDD_MAIN, and PP_BATT_VCC

Since these phones are getting a bit long in the tooth it might be time for an upgrade if you do not have the correct equipment to diagnose and repair the problem as it will cost about $100 for a shop to repair it.
