Ubiquiti BLANCO-AZUL-APAGADO on UniFi: TFTP recovery mode LED
Risk level
Low
Usually safe to check without specialist tools.
Urgency
High
Quick answer
When your Ubiquiti UniFi device LED flashes white, blue and off in sequence, it has entered TFTP Recovery Mode. Verify that the physical Reset button is not jammed, try a normal reboot or factory reset, and upload the official firmware via HTTP or TFTP if needed.
Safety first
Stop and check this first
- Do not manually reboot or unplug the UniFi device while TFTP or HTTP firmware recovery is upgrading: Ubiquiti warns that you must let the device finish and reboot automatically.
- Never open the UniFi device casing or PoE injector; if the Reset button is physically damaged or Recovery Mode fails, use the official RMA portal.
Safe checks you can perform
- Verify the Reset button clicks cleanly and reboot the device
- Attempt a standard factory reset before full firmware recovery
- Upload firmware via HTTP Recovery UI on Gateways or Switch Ultra
- Transfer the .bin firmware via TFTP to 192.168.1.20 on Access Points
Leave these tasks to a qualified professional
- Do not attempt this professional task: Technical diagnosis with Ubiquiti Support
- Do not attempt this professional task: Device replacement request via the Ubiquiti RMA Portal
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Technical diagnosis with Ubiquiti Support
What they doIf your UniFi device stays in the white-blue-off LED pattern or fails to accept firmware over HTTP (192.168.1.30 / 192.168.1.20) or TFTP (192.168.1.20), reach out to the Ubiquiti Support team.
They must show youthe exact firmware .bin version used and the HTTP or TFTP transfer logs recorded during recovery.
In writingthe Ubiquiti Help Center ticket reference and the support team's technical findings.
Device replacement request via the Ubiquiti RMA Portal
What they doIn the rare case where UniFi Recovery Mode does not rectify the unresponsive device, submit a hardware replacement request through the official Ubiquiti RMA Portal.
They must show youproof that the device remained unrecoverable after following the official Recovery Mode procedure.
In writingthe RMA authorization number from rma.ui.com and the replacement unit details.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Verify the Reset button clicks cleanly and reboot the device
- Who:
- you.
- How:
- check that the physical Reset button is not stuck and clicks normally when gently pressed, then unplug the UniFi device from power or PoE and reconnect it without touching the Reset button.
- Result that matters:
- exit TFTP mode if it was triggered accidentally or by a stuck button.
- If the device boots to steady white (ready for adoption) or steady blue (normal operation):
- no further recovery is needed.
- If the device remains unresponsive:
- try a standard 5 to 10 second factory reset before running Recovery Mode.
- Evidence to keep:
- short video or note of the LED pattern after power-cycling without touching Reset.

Attempt a standard factory reset before full firmware recovery
- Who:
- you.
- How:
- while the device remains powered on, hold the Reset button for 5 to 10 seconds until the LEDs indicate factory restoration has started, then wait for it to reboot and restore your settings from a cloud backup if applicable.
- Result that matters:
- follow Ubiquiti's rule to use Recovery Mode only when a standard factory reset cannot be performed.
- If the factory reset succeeds and the device returns to steady white:
- re-adopt or restore from backup.
- If standard factory reset does not work:
- proceed with firmware upload in Recovery Mode.
- Evidence to keep:
- screenshot or status of the device in the UniFi Network application after the reset attempt.

Upload firmware via HTTP Recovery UI on Gateways or Switch Ultra
- Who:
- you.
- How:
- for Cloud Gateways, Independent Gateways or Switch Ultra in Recovery Mode, download the latest official .bin firmware, set your computer Ethernet adapter to a static IP in 192.168.1.0/24 (such as 192.168.1.11, subnet 255.255.255.0), connect to Port 1 (Port 18 on Dream Wall, Port 2 on EFG), and open http://192.168.1.30 (Gateways) or http://192.168.1.20 (Switch Ultra) over HTTP only to upload the .bin file.
- Result that matters:
- reinstall the firmware image through the built-in HTTP Recovery Mode web interface.
- If the firmware update finishes and the unit reboots normally:
- restore your computer to automatic IP.
- If you are recovering a UniFi Access Point:
- use the TFTP transfer method to 192.168.1.20.
- Evidence to keep:
- screenshot of the HTTP Recovery Mode page confirming the firmware upload.
Evidence: UniFi Recovery Mode
Transfer the .bin firmware via TFTP to 192.168.1.20 on Access Points
- Who:
- you.
- How:
- for a UniFi Access Point flashing white-blue-off, download the latest .bin firmware, connect your computer to the same network or the PoE adapter data port with static IP 192.168.1.25 (subnet 255.255.255.0, gateway 192.168.1.20), and use a TFTP client in binary mode to put the .bin file to 192.168.1.20, allowing the AP to reboot automatically.
- Result that matters:
- recover an unresponsive UniFi Access Point using TFTP Recovery.
- If the AP completes the upgrade and automatically reboots to steady white or blue:
- recovery is complete.
- If Recovery Mode fails to restore the device:
- contact Ubiquiti Support or submit an RMA.
- Evidence to keep:
- screenshot or terminal log of the completed binary TFTP transfer to 192.168.1.20.

What it means
According to the Ubiquiti Help Center ('Understanding Device LED Status Indicators', 'UniFi Recovery Mode' and 'How to Reset UniFi Devices to Factory Defaults' covering UniFi Access Points, Cloud Gateways, switches such as Switch Ultra and USW Flex Mini, and consoles; other models may vary), the 'Flashing White-Blue-Off' LED sequence indicates that the device is in TFTP Recovery Mode. It is triggered by holding the Reset button while powering on (or holding it too long during a reset), by a physically jammed Reset button, or by power loss during a firmware update. This LED state alone never proves that the hardware is permanently broken.

Symptoms and causes
Probable causes · in order
- Reset button held while powering on or held too longCommon
Ubiquiti explains that holding the Reset button before powering on, or holding it longer than the 5 to 10 seconds needed for a factory reset, puts the device into TFTP Recovery Mode.
Evidence: UniFi factory reset instructions · Understanding Device LED Status Indicators
- Physically jammed Reset button on the device housingPossible
In the LED status guide, Ubiquiti notes that if entering TFTP mode was unintentional, you should check that the Reset button is not jammed and still clicks when pushed.
Evidence: Understanding Device LED Status Indicators
- Power loss occurring during a firmware updateCommon
According to the UniFi Recovery Mode guide, an unresponsive device requiring recovery often results from an unexpected power loss happening at the same time as an update.
Evidence: UniFi Recovery Mode
- Unrecoverable firmware or internal storage failureLess common
Ubiquiti states that in rare cases where Recovery Mode does not rectify the issue (or when storage fails repeatedly on a CloudKey), the device must be replaced.
