How To Get Unifi Ap Out Of Tftp Mode

Ubiquiti'south Petty File Transfer Protocol (TFTP) recovery method is the process followed to recover firmware on Ubiquiti devices. This method is useful when there is an unstable device connexion or when the device cannot be accessed. These difficulties are typically due to some form of firmware corruption. Firmware corruption tin occur due to a number of reasons, only the most common is by Electro-Static Belch (ESD), and ESD often occurs due to the utilise of unshielded cable and connectors.

Fortunately, Ubiquiti's TFTP recovery method allows the recovery of firmware on most Ubiquiti devices. In this article, we explain how to perform this recovery. Watch our video below for more info.

1. Prepare Prerequisites for a Ubiquiti TFTP Recovery Process

Earlier attempting the recovery, perform the following steps:

Download a TFTP server/client such as PumpKIN TFTP.
Download the Ubiquiti firmware related to the device that you are looking to recover. You can detect it in the download department of Ubiquiti'southward website.
Have a paperclip or like object on manus to press the reset button of the device. Configure your PC's IP address to be in the range of the default IP of the device. ie. 192.168.1.xxx where "xxx" is whatever number between 1-254, excluding 20. This will allow yous to communicate with the device.

2. Put the Ubiquiti Device into Recovery Mode

Yous are now ready to offset the process of recovering the Ubiquiti device. Commencement, you'll need to put the device into Recovery Style. To do this, perform the following steps:

Start a continuous ping to the device'due south default IP (192.168.ane.xx) e.g.
Windows: ping -t 192.168.1.20
Mac: ping 192.168.1.xx

Hold in the reset button on the device while powering the unit up. Go on the reset push pressed for 20 seconds. Y'all will and then see all the LED's on the device lite up and wink 3 times earlier going into a sequence of 2 LED's flashing, then alternating 2 LED'southward flashing.

The device is now in recovery mode and able to accept new firmware packages.

three. Recover your Ubiquiti Firmware

To recover your firmware, perform the following steps:

Open the PumpKIN TFTP client
Click the "Put File" pick
At "Local File" click the button on the right, navigate to and select the downloaded firmware for the unit.
At "Remote Host" type in the default IP of the device i.e. 192.168.1.20.
Click "OK"

When y'all click "OK", the client should start transferring the firmware to the device and one time done, the device volition install the firmware and reboot.

If the correct firmware was used, you will see the customer study that the transfer was successful. If you see "Firmware Bank check Failed", the incorrect firmware was used.

Once the unit is done and rebooted, yous will see that the firmware on the device has been updated.

This should fix whatever software related bug that might be plaguing the device. You may even exist able to recover a device that was previously inaccessible via the Ethernet with this method.

Good luck and happy recoveries.
