Sure, did it once when I returned my device for repair. Just go to maintenance section on the device and format the internal FAT-disc. After the format the Firmware (FW) will copy a fresh image to the internal FAT-disc with some basic configuration and will start if it was the same when you started if for the first time (you need to accept the licence, configure language etc). Make sure you made a backup of the internal disc because everything on it will be wiped! One thing though. Some older versions of the FW didn't correctly format the internal FAT-disc but I don't how serious that bug was. Which FW are you now using?
