I am new to the forum and realise this topic has not been posted to for a while but hopefully that won't stop me from getting a reply.
I have the exact same issue with my HS-DHGL-EM090 - NAS Navigator detects and states Emergency Mode, in red.
I followed the instructions, as posted by "davo". I disabled Windows firewall and my Virgin Media router firewall.
I have tried the update with my buffalo device plugged into the router and also with it plugged into my computer.
I tried the update with DHCP enabled and without DHCP enabled.
The LSUpdater.exe "finds" my buffalo device both with DHCP enabled and disabled but the update always stops and gives this error message:-
'Couldn't confirm a response from HS-DHGL-EM090.
please check a network address of both PC and HS-DHGL-EM090
please disable the Firewall function if it is working on PC
Updating is aborted.'
So, does this mean my device is broken and cannot be fixed?
Thanks for reading.
