I bought a UDM Pro in April 2021. I decided on a whim to reboot the device this weekend after buying a new modem... Anyway, it 'rebooted' and bricked itself after 4 years of service. I had auto updates off, and the device has been on a UPS since day 1.
It 'takes longer than usual' then eventually hits a 'unable to retrieve status' or 'reboot' screen. Then it never boots... cannot get into recovery mode, cannot factory reset, and none of the ports respond (although the lights turn on when plugged in?)
I contacted UI support and explained my problem - they helpfully told me I was screwed and the device is out of warranty...
So asking, because I'm on the verge of quitting UI as a company -
