Ring Doorbell Pro stuck in firmware update

I've had my Ring DoorBell Pro installed now for 5 years now and it's been pretty faultless in that time. It's hardwired with the Ring transformer & bypass kit, and its been great. This weekend, the doorbell stopped recording video around 3am on saturday - seemingly to install a firmware update - and since then, has not reconnected to my wifi. The lights on the doorbell show it's in firmware update mode (pulsing white light), and every 5-10 minutes or so it will restart itself, but always goes back to the firmware update mode setup. It will not go into setup mode. Things I have tried include: Hard reset (hold down until you get the flashing lights, wait a bit longer and release) Setup mode new setup on the app, new install of app, removing from account & re-adding etc network reset & router reboot Completely turning off the power to my house, waiting 2 min and then booting it up again. disconnecting the doorbell physically and re-installing to the wall Whatever i do, it refuses to enter setup mode and stays in firmware update mode. I have tried ring support and currently waiting for a supervisor, but after going through the above with them, all they want to do is offer me a meaningless 30% discount off a new device....for a software problem that THEY caused. Any suggestions where to go from here/ I'm getting ready to submit a small claims court case against them if they don't help further - this is clearly not a hardware fault or a warranty issue - its fairly obvious that it tried to update its firmware and has gotten stuck. This is not a hardware issue and is totally nonsensical for them to suggest it is! I will gladly take them to court over this if its needed to prove the point if nothing else - companies cannot remotely brick our devices and then expect us to pay for a new one, its a little ridiculous :) Id rather fix this one though if at all possible, so any suggestions are greatly appreciated! :)
