SIP-T46s Bricked after latest firmware update.

[daniel.broome]

Hi There,

We have a T46s phone and have attempted to update the firmware to the latest version 66.86.0.5

The phone was working after the firmware was installed, but when it was restarted now the phone is dead. There is nothing on the screen and no sound from the handset or when trying to change the volume.
We can only see the Red LED notification light.

I have tried to reset it, by holding down the speaker button and turning it on and nothing, also have tried powering with POE and the AC adaptor that came with the phone.

Please help.
