I believe I saw this on FB group, since I 've never been able to reboot modem holding the defrost button I've always been able to reboot using IHU button.
Now I turn on defrost first then press and hold defrost button and after 15-30 secs I see the small x appear in internet triangle followed by SOS flashing red and finally everything resets within about another minute.
Rebooting the IHU I never saw the SOS flash red. Hope this helps somebody having comms problems.
