Omnia unreachable after 3.9

I have two Omnias. The edge router handled the 3.9 update perfectly.
But the internal omnia running as AP went unreachable after it sent its notification email. It did roam the wifi with internet access as it should.
But LEDs did not show any access and it was unreachable in every way. No open ports when scanning it.
I did a reboot, several 2-led reset as well as a cold boot but it did not help.

On the third 2-LED reboot it booted back up into 3.8.6 again.

I sved the config backup and disabled the automatic update.

Any one else who have suffered from something like this with 3.9?
