DO NOT UPDATE YOUR BRIDGE PRO
i just spoke with their customer service after my bridge bricked. They said they’re getting lots of calls and investigating this. So, turn off your auto update and DO Not update!
Update:
It appears that not everyone is affected. Only Philips may know why. There may be different revisions of the board. Nevertheless, the pain of having to set up everything all over is so great, that I will not ever update my bridge again. This has been the biggest disaster in my home automation journey in the last 10 years. All my original Hue bulbs that were my first smart devices, which I got more than 10 years ago, are still running.
It’s quite ridiculous that Philips has not provided a backup solution. Until they do I recommend not updating your bridge ever, or not use the bridge at all.
