HT-H7608 constant reboot after setup

Hi,

I just picked up a pair of HT-H7608s (V1.1).

I plugged them in, connected to the default setup interface and configured them no problem.

When they rebooted, they got an IP address on my LAN and I connected to their web interface but before I could enter a userid and password they reset. Both are doing the exact same thing.

LED startup sequence: solid red - flashing red - solid red - blue/green for a second -solid blue for 30 seconds - flashing red.

I have tried doing a factory reset but that doesn’t make any difference.
I have not updated the firmware as I have not been able to login to even see what firmware I have to start with.

I am using the supplied power supply and have tried USBC power too. It does not help.
