That is an error listing the files in the device storage. This has been known to happen with some
devices when they contain SD cards. If you remove the SD card, you should be fine. You can try reformatting the card
or using a different card as well.

If you arent using an SD card then, the remaining options are resetting the device or using a wireless transfer method.
