Openreach ONT not booting

[freezone]

Internet doesn't work and I see all 4 port lights flashing. What's wrong?

Have you had any lightning?

Turn it off for 2 minutes.

If that doesn’t fix it there should be a pin reset button, hold that in until it reboots.

If it’s still not working ring your provider as it will likely need changing.

I've done all those steps with no luck. Thank you

Installed and replaced hundreds of them 4+2 ONT’s over the years.

Came across that fault quite often, in fact it was so common we had a nickname for it. Disco Lights of Death or something like that.

Basically yeah, it’s Ducking Ducked Ducked and will need to be replaced.

Good luck reporting a fault through BT.
