Default (HELP) Access internal storage in MSC

Hello,

Today I wrecked the touchscreen of my Xperia Z. However there are videos and photos on the internal storage that I really want to keep. The problem is that the device is currently set to MSC and not MTP. Therefor I can't access the internal storage.

Is there a way to still access internal storage in MSC?

Is there a way to switch connection types without using the touchscreen?

It would be amazing if someone could help me out on this. My phone is not rooted and runs the latest firmware (Feb 2014).
