UniFi Cloud Key emergency recovery overview and steps

For system image recovery, we have a rescue image built in. In the case something bad happens during system image update, you can enter the rescue UI via the following steps: 

1. Power off the system
2. Press and hold the reset button and then power on system
3. Keep reset button pressed for about 10 seconds, or until you see the rescue LED pattern (off->white->blue, looping)
4. Then you can access the rescue web UI. The IP address comes from your DHCP server or you can access it at the fallback IP of 192.168.1.30. 
5. From the rescue web UI you can reset the unit to defaults, reboot/power off, or directly load a firmware file to recover the CloudKey.

If you wish to load a firmware file you first need to download it. Find the latest public releases HERE.
