Hi,
I have also had the multiple reboots and then it fails back to the previous version.
I was supplied various betas to try by Draytek UK as I needed the extra SSID's in managed Wireless AP Profiles.
Funny thing is that the MDM1 version of 3.9.5 installs OK and is stable yet the router refuses to take the BT variant.

I have even tried exporting my config and then resetting to factory defaults and the router still fails to boot with the UK variant even before I have had a chance to restore my config. Back to using MDM1 which works.
