I have a couple of Airgrids that I'd like to use during field day for mesh nodes, but after I'd like to have them back to stock to use bridging two sites. Has anyone sucessfully reloaded the factor software on a Ubiquity device after it's been a mesh node?

Thanks,

Bernie

Yes. TFTP the firmware back to the device.

No luck here using the latest 1.2.1 firmware on a Rocket M2 using the OEM "Recovery" method of depressing the reset switch during power up for 8 to 15 seconds. Unit still boots up normally to normal BBHN operation. Using the firmware upload method aborts with "firmware not recognized". I can feel the tactile depression on the reset button, but no luck after several attempts. Does anyone know if this method really works? It appears the BBHN firmware has disabled this recovery method. It normally should revert back to the factory IP (192.168.1.20) to allow TFTP upload of the OEM image, however, it appears this is only true if you have factory OEM firmware in the M2 already. So, how do we get back to OEM firmware?

Thanks in advance for an experienced answer,

The TFTP method works, I've done it 50+ times personally to restore to factory image.

You have to hold the button until the indicator lights change to indicate it's in TFTP mode.

The BBHN firmware takes no action to enable or disable the TFTP recovery mode. This is handeled before we boot our software.

Thanks for the reply. I've got to bring it down from the tower to the bench to attempt this is a more "controlled" environment ;-). I been attempting this with me on the tower and another on the ground cycling the POE supply. I thought I could pull it off, but obviously not. Exactly how do the LEDs change? I see power and network activity under normal conditions on power up boot now.

Thanks again.

I've seen multiple combinations, all involve the RSSI led's (the network activitiy and power are not relevent)

It involves some form of the link led lights comming on in one configuration as you hold the reset button THEN plug in the power some of the LINK led's will be on and then they will change to different set of LED's in a repeating pattern

You can find several samples on YouTube for TFTP Ubiquiti Recovery that will show various diffrent LED.

The most common I have seen is  2 LINK LEDs are on as you power on holding reset, than it changes to a diffrent set of 2 LED's at which time you can release and it will become alternating 1+3 followed by 2+4 and repeat.
