I just installed the FW 9.50 release on my 1030. Now, when I connect the 1030 to my PC and and start GE, GE says that the 1030 is up to date with 9.10. GE 6.21 on Win10 x64. Screenshots below:
I would not worry about it. When the files get uploaded to GC, it will show the correct FW version of the device. My experience is GE does not seem to know the FW version of the device unless it has downloaded it to the device.
I suspect there is something going on with the latest Edge FW roll out otherwise Garmin would not have put the zip file in the forum for each of the X30 devices. My wife's Edge 830 updated in the pushed 10% via WiFi, but also showed up in GE. My Edge did not get it, so I updated via the forum ZIP file. Mine still shows the previous version in GE. It will eventually get sorted out. Maybe when the next FW is released. It does not cause any problems that I can tell at the moment.
