I had some success with nRF - you need to download the firmware zip file to your phone, then connect to the DFUTarg. I found I had to keep clicking Retry every time there was a connection drop (which was like every 1-2% of the data transfer). It did incrementally pass the update to the watch, even though it didn't seem like it was doing that. Once I finally got to the 100% point, everything else happened as it's supposed to with the reboot.
