i suddenly lost my sim signal and mic wasn't work too. also phone wasn't charging the same.
i took it to a fixers place.. they told me u gotta bring us a phone like it even if its crashed we only need to see directions of wires of the connector so we can reconnect the connector to the phone board and the flat that contain the three materials: the sim signal and the mic and charging socket to the connector... i just need a map of the directions how to put back that connector on the phone board ..
sorry for my awful English guys
my best regards
