If the Gyro sensor IC is damaged, it will do not work even thought power is supplied and MSM8974 controls normally. Therefore if the Gyro sensor is damaged, change the Gyro/Accel sensor IC or main board. # Gyro and Accel functions are combined to one chip (MPU6515) Change the Gyro/Accel Sensor IC (U11001) START Yes No No Yes Yes Is the function normal operation? Is the function normal operation? Change the main board Is the function normal operation? Check the Gyro/Accel sensor function END END END
