Default Help me do a small modification of android

I have found the file to modify

-    <!-- Shutdown if the battery temperature exceeds (this value * 0.1) Celsius. -->
-    <integer name="config_shutdownBatteryTemperature">600</integer> reads this value and compares with the temperature reading and issues a shutdown command.

 private void shutdownIfOverTempLocked() {
        // shut down gracefully if temperature is too high (> 68.0C by default)
        // wait until the system has booted before attempting to display the
        // shutdown dialog.
        if (mBatteryProps.batteryTemperature > mShutdownBatteryTemperature) {
   Runnable() {
                public void run() {
                    if (ActivityManagerNative.isSystemReady()) {
                        Intent intent = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);
                        intent.putExtra(Intent.EXTRA_KEY_CONFIRM, false);
                        mContext.startActivityAsUser(intent, UserHandle.CURRENT);
How do I modify this value?
