Hi, Connect the phone to a PC (be sure your cable is working). Try to switch it on. If the PC recognizing your device 90% you have a SW problem. Try to restore the phone: [guide|55047] If your PC does not respond when you connect the device, then the problem is hardware, broken USB connector, logic board damage... Regards.
