Getting a UBNT device into TFTP firmware mode - remotely...

It had to happen. We have 200+ UBNT and 20+ mimosa devices in the field, held together (rather well!) by around 30 netonix devices.

One of the UBNT's came up with the 'Error A-12' where the firmware thinks it's been compromised. UBNT support read their scripts and basically told me to run TFTP firmware restore. Which is fine - I've done it tens of times in the past.

Problem is, this device is mounted on top of a three storey Scottish Baronial castle, and involves a scramble up a slate lined roof. Which in this weather (Scotland is in danger of being washed away this week- even more rain than normal) is not a safe or healthy thing.

So - wondering if anyone had successfully managed to put a netonix switch connected UBNT device into TFTP mode?

It's a long shot, but I figured if anyone had - the people in this forum would have.

Many thanks in advance,

You have to unplug the device from the switch then use a POE brick that has a reset/default button.
