As a proffessional Software Test Engineer For a Blue Chip Company I can absolutly assure you that all hardware device firmware is downgradable. In fact if an upgrade caused a corporate customer any issues…
Garmin is far better at creating bugs than fixing them. There is no excuse this far in to the prouct life cycle for all these issues. It's not like the product is continually evolving with rich feature…
It seems the current 6.90 for VA3 killing lots of watchface.
Hope Garmin is fixing the bugs soon ( that 'dont exist ;-) )
Sorry, but You can't do it.
What to do if the firmware failed?
You should see it positively. So far, it only happened once (compatibility with an watchface). And it was possible to start the clock after full reset. Option to exchange the watch remains an option too.
As a proffessional Software Test Engineer For a Blue Chip Company I can absolutly assure you that all hardware device firmware is downgradable. In fact if an upgrade caused a corporate customer any issues this would be a standard recovery proceedure, to roll back the firmware to the last known good version.
In fact this how a firmware upgrade is tested, by downloading previous firmware levels and then upgrading to the latest level, this will be carried out hundreads and hundreads of times as part of a standard FirmwareDownload test.
So yes of course Garmin have the ability to downgrade firmware, they just choose not to make this feature availible to the customer, as in doing so would be an admission of releasing a bad firmware build into the wild. That might lead to legal action on a mass scale. So it's better just to deny there are any problems, or that you are the only one with this particular issue and we have never seen it before. Then quietly work on it in the background and hey presto the next release fixes everything lol...
