I've just purchased a new white FR955 Solar, opened the box myself. It has version 9.11 and Garmin says it's up to date. Any idea why this might be?

All,
As most of you already know, we are aware that a number of X55 devices are unable to update. If a Product Support agent has not already added you to the report, please tag me with permission to reach…
All,
Software version 15.19 has been made available, so anyone who syncs through Garmin Express should now be able to update their unit to that version. If you would like to enroll in our Beta Software…
I have just received a response from Garmin support:
The update issue is a known issue we are working as hard as possible to resolve.
I have added your information to the case and you should get an email…
Interesting. This appears not to be a delta update.
The metadata seems to imply it should only apply to 14.05 or later.
<partNumber>006-B4024-10</partNumber>
<version>1519</version>
<update>

</update>
The bulk of the update is obfuscated in some way.
In what way?
Where do you get your knowledge about Garmin firmware? I couldn't find any useful information and I don't think Garmin's gonna share any.
