Remove dock flex see if work without it then replace it might be short and cause this faults,check also on board dock connector if clean not broken some part of this connector if so you might misplace it and cause such fault.

Try other battery for testing.
Is there some other fault like no imei always searching etc?
Because restarting can be if battery ways are damaged or if BB CPU have crack in balls after dropped,you say that you chk NTC and Gas Gauge make other reading chk resistance to GND of NTC and Gas Gauge at diode testing hold red to GND and with black chk if some not show readings it would mean it is broken.
