Bridge update bricks device

Have two bridges that have been boxed up for a year (Aus). Been using apple home so haven’t needed them till now, but pulled them out to integrate with Google Home. Device connected to wifi, then after letting it reboot and leaving over night the device shows “error code 12, device needs replacing”.
Exact same happened to second bridge, both were brand new out of the box.

Your support refuse to do anything about it. Devices bricking themselves out of the box is an issue for the developers.
