AP UniFi AC LR dead after firmware update

[ Edited ]

Hello, AP UniFi AP LR dead after firmware update. No LED indicator is blinking, TFTP method already try but no luck.

Power is OK and Ethernet interface is up at 1Gb.

I have USB programmer for a flash chip. Is there a firmware dump or something to restore AP?

Re: AP UniFi AC LR dead after firmware update

Hello @tweaxl,

 

To what firmware version did you try to flash it with a TFTP Recovery?

 

What is the MAC address of the unit?
What is the datecode?
What firmware was previously installed?
What firmware version did it upgrade to?
Controller version?
Was auto upgrades turned on?
Did you press the upgrade button in the controller or did you upgrade via CLI?
Was it POE+ powered or 24v?

 

 

 

Regards,

Glenn R.

Can you go to our rma site:

https://rma.ui.com/

fill it out, once you get the RMA # back in an email.  Send it to me, so  I can run it up the flagpole.

 

Thanks,

Jeff
