Welcome to Android Central! I assume you've already swiped down the notification panel to look for the USB icon, correct? If you don't get an option to switch to MTP, then it could be that the firmware is corrupt, or the microUSB port is faulty. Make sure the microUSB port is completely clean. If it is, then try reinstalling the firmware. If the problem persists, then you might have to consider replacing the microUSB port.
