i have connected a DC 9v to the micro usb connector to the end in a various ports to data +- and to power in supply, and the phone stopped to operate suddenly .Do you know what is the problem ? Is the main board or the board of the micro usb connector .?Is there any way to find the damage ? or to fix the main board? Thank you
At least see the reaction to the charger, connect the charged battery, connect to the laptop/desktop.
It is quite difficult to say what to do if the phone is not starting, loading, or launching.
