Oh ok. I assumed you'd needed to use cure because you stated in Post #3 that it froze after the Garmin logo screen displayed.

So what had likely caused that freezing do you think? It clearly wasn't 'bricked' in the usual way by a corrupt file onboard if simply loading the full dezl fw recovered it. Had you tried using hybrid fw previously with the DriveSmart boot.bin combined with remainder of dezl fw?
