There are two steps for the firmware update - two bad Garmin doesn't warn people upfront.
The first update is preparing for the ANT stick - it takes about two minutes.
The second step is the core of the firmware(software per Garmin) update which takes about 10 to 15 minutes depending on how busy the Garmin Connect site is.
Since you already got through and got the "unsuccessful" message, I assume you already know how to start the update properly.
To finish it - Make sure you do not interrupt the process, just let it run through the 2 steps mentioned above. And be patient - the 2nd step follows the 1st step automatically. Don't touch the bezel and change screen during the update, just leave it alone. It took me a few times to get it done successfully because after the 1st step finished, I started to flipping screens to find out if it get updated to ver 2.50, before I found out there would be step 2 coming automatically.
If you see the process bar moving after the 2nd step and see "software loading" you are in for good.
Hope this may help.
