I flashed the below rom.

But I found I Can't close the USB storage device after opening it. The button Open the USB storage device will not change to Close the USB sotrage device after I open the USB device. All ringtones and alarms I defined will be returned to be default one. I need to reboot the phone to correct it. Is there any other good solution for it? Thanks.
