It’s possible there were other backups. I only see one from about 45 mins ago. Again, just getting started and only plugged in my HE for the first time yesterday.
Interestingly, after rolling back to the previous version (2.2.4.158) and pulling my MAC address from hub details (for the Diagnostic Tool login), I checked and downloaded the most recent backup and then returned to the diagnostic tool. When I clicked restore previous version it listed the new firmware (2.2.5.119) as the restore option, which I chose to restore. For whatever reason that fixed it.
So to recap. I upgraded, which failed to launch to UI after >45mins, then restored to 2.2.4.158, then restored back to 2.2.5.119. It successfully loaded from the restore.
Odd. But it’s now working on the new version.
