UniFi Recovery Mode

2023-09-22 17:47:14 UTC

Recovery Mode is a last-resort solution to recover an unresponsive UniFi device, often resulting from power loss occurring at the same time as an update. Only use Recovery Mode if you are unable to perform a standard factory reset.

Note: UniFi Power Backup can prevent unexpected power losses from occurring.

The following UniFi devices support Recovery Mode:

  • Dream Machine, Dream Machine Pro & Dream Wall
  • Access Points (all models)
  • Cloud KeyCloud Key Gen2+
  • Cameras
  • USW Flex Mini

Before Considering Recovery Mode

If you are considering Recovery Mode, first check two key points:

  1. Reboot your UniFi device. If this resolves your symptoms, no further actions are required.
  2. Factory reset your UniFi device. If you have cloud backups, you can easily restore your settings after factory resetting. If a factory reset works, no further actions are required.

Performing a Device Recovery

Dream Machine, Dream Machine Pro, Dream Router, Dream Wall & Next-Gen Gateways

  1. Download the most recent firmware for your device, found here.
  2. Completely power-off the UniFi device and unplug it from its power source.
  3. Press and hold the Reset button and then reconnect it to the power source.
  4. Continue holding the Reset button for 5 seconds, or until the display (in supported models) indicates Recovery Mode.
  5. Connect an Ethernet cable from your computer to the first LAN port (Port 1). This is usually the port nearest to the top left corner.
    • Note: Connect to the Dream Wall via Port 18, not Port 1.
  6. Configure a static IP address on your computer in the 192.168.1.0/24 range (for example, 192.168.1.11).
Windows Client
  1. Navigate to the Windows 10 Network connections
    • Settings > Network & Internet > Status > Change Adapter Option
  2. Modify the IPv4 settings of the Ethernet adapter
    • Ethernet Adapter > Properties > Internet Protocol Version 4 (TCP/IPv4) > Propertie
  3. Select the option to manually enter an IP address and add the following information:
    • IP address: 192.168.1.11
    • Subnet mask: 255.255.255.0
    • Default gateway: <blank>
    • DNS servers: <blank>
macOS Client
  1. Navigate to the mac OS Network connections.
    • System Preferences > Networks > Ethernet Adapter
  2. Select to manually enter an IP address and add the following information:
    • IP Address: 192.168.1.11
    • Subnet Mask: 255.255.255.0
    • Router: <blank>
    • DNS server: <blank>
  1. In a web browser, navigate to http://192.168.1.30 to access the Recovery Mode UI.
    • Note: The Recovery Mode UI is accessible via HTTP only (not HTTPS). Your browser may try to redirect your session to HTTPS. Use a different browser if necessary.
  2. Select Firmware Update > Choose and browse your computer for the previously downloaded firmware (.bin) image file.
  3. Wait for the upgrade process to complete and reboot the device afterwards.

Access Points

  1. Download the most recent firmware for your device, found here.
  2. Connect your AP and computer to the same network or VLAN, either through a PoE switch or by connecting the computer directly to the network (data) port on the PoE adapter.
  3. Press and hold the Reset button, and connect your computer to the available ethernet port of the AP.
  4. Continue holding the Reset button until the LED flashes white, blue, off as indicated in our LED Status Guide. This indicates your device is ready for TFTP Recovery and you can release the button.
  5. Set a static IP address on your computer to communicate with the AP, which has a default IP address of 192.168.1.20. The following is an example configuration:
    • Static IP: 192.168.1.25
      Subnet: 255.255.255.0
      Gateway: 192.168.1.20
  6. Use TFTP to move the firmware from your computer to your AP. There are various programs and methods for accomplishing this. Here are two methods for your reference.
    • Windows
      1. Use the built-in TFTP command line tool, or a separate program such as Tftpd64 or pumpKIN.
      2. Select the downloaded firmware image and transfer it to the AP.
    • macOS and Linux
      1. Open Terminal
      2. Enter TFTP mode by entering the command: 
        tftp
      3. Once in TFTP, paste the following commands and hit enter. 
        connect 192.168.1.20
        binary
        rexmt 1
        timeout 60
        put /path/to/firmware_name.bin
  7. The file transfer will begin. The firmware will upgrade and the device will automatically reboot once it has finished. Do not reboot it yourself.

Cloud Key
