Hi,

The media storage in Nexus 4 is not from a individual partition so it can't be un-mounted then set to mass storage mode. Instead of that Nexus 4 used fuse technology to re-use the /data partition. This means that the media storage actually is emulated by a folder in /data partition via fuse.

Please also refer to the bug as below for MTP used to this kind of device to share files between device and PC.

It should be the typo of "Enable USB storage"
