bricked m5 nanostation

I have a 5g nano xm that had been working with the 3.19.x.x software. When I tried updating to 3.20.3.1 using UI the lights on the node all flashed and then only the green power light on the left side remained on. I tried to tftp it and it does not respond at all. I cannot make it do anything.

Do any LEDs illuminate when you apply power?

The left green light is all that comes on. It is on steady, not blinking.

"The left green light is all that comes on. It is on steady, not blinking."
Then you can make it do something.

Can you get the device into TFTP mode?

Backing up to your original post... After you:
"When I tried updating to 3.20.3.1 using UI the lights on the node all flashed and then only the green power light on the left side remained on. "

How much time elapsed between that and this:

"I tried to tftp it and it does not respond at all."

I hope at least 6 minutes.

I tried to tftp within a couple of minutes and then I tried a few days later and nothing happened. Np other lights did anything and the green light stayed on.

"I tried to tftp within a couple of minutes "
Uh oh.
The firmware upgrade takes at least 4-5 minutes.
Remember that last page after the upgrade...something about 'do not remove power' until the update is finished' ?

I fear that
"I tried to tftp within a couple of minutes"
removed power before the update finished.

It appeared that the node was

It appeared that the node was updating and that screen was showing and after a few minutes the screen went blank and said it could not connect. I opened a new screen and typed localnode:8080 and nothing happened. I noted only one green light on the left side, which did not seem right and that is when I powered off and tried to tftp.
I should have described the event in better detail. I have had the screen go blank after an update before and it usually meant it has loaded.
In any event, where do I go from here?
Thanks for your thoughts.

Can you get the device into TFTP mode?

Next time wait for the node to reboot...twice.
Umm rephrase...you wait once throughout both of the node's reboots.
There may be a period of time wherein there is only one green lamp.
This may not be an indication that the update is finished.
Do not remove power from the node until the update has finished.
This may take many minutes (4-6 minimum).

Does the node give your PC a network address?
Does the node respond to pings (192.168.1.1 or 192.168.1.20)?

Itried 192.168.1.20 with no response. I didn't try the 1.1 address

Also connect the computer and

Also connect the computer and node through a simple Ethernet switch (dumb switch) so that the switch can maintain the computer’s network link while the node is being rebooted. That may help in the TFTP mode.

I have been using a switch as xw's seem to need that.

I can get it into tftp mode

I can get it into tftp mode but the address is not a ubiquiti address. I think it must have an aredn address since that's what it was opersting on before bricking. When I push reset, the far right green light flashes at a quick rate for 10seconds or so and then there's a flicker from the center lights and then all go out except for the left green light. It goes into tftp mode but don't know where to go from there.

Your node should respond to

Your node should respond to 192.168.1.20 and I see you have been here for a few years but I have to ask is your PC in static mode?

It is in static mode.

It is in static mode.
Let me refresh. I have a nanostation that is xm and has had aredn software on it for several years. I was updating  using UI when ithe computer screen went blank and the node lights blinked off. After a minute the left green light came on solid. I have tried the reset button and the right light flashes and then goes back to the lleftt green light on solid. I have set static at 192.168.1.40 and tried 192.168.1.20 and 192.168.1.1 but it is not recognized. I have put it into tftp mode and tried installing the software but command prompt does not recognize the request.
It was suggested I didn't wait long enough on the initial update. This is possible.
I set protocal to dhcp and tried localnode:8080 it gives no result.
 If it is not fixable I will trashcan it but was wondering if there is a fix first.
I think everyone for their input.

"the computer screen went blank and the node lights blinked off. "

Sounds like a power interruption.

"I have put it into tftp mode and tried installing the software but command prompt does not recognize the request."

Please do not attempt to interpret what happened, please show us the command and the response.

Please follow the TFTP install method. If it fails, copy and paste the error in a reply.

If you can put the device into TFTP mode, I am 99% certain it is not bricked.

Ok. I was doing a sysupgrade but have pushed the reset button. Do you want me to try the factory os sysupgrade software?

Do you want me to try the factory or sysupgrade software?

I suggest you follow these instructions:
https://arednmesh.readthedocs.io/en/latest/arednGettingStarted/installing_firmware.html#ubiquiti-first-install-process
Note:
"Download the appropriate factory file for your device by following the instructions in the Downloading AREDN Firmware section of this documentation."

Could you ping 192.168.1.20

Could you ping 192.168.1.20 before you attempted the tftp?
Also a suggestion.  Rename the file to something simple - like factory.bin and put it into the folder that you are operating from.  Saves typing and dramatically reduces the likelyhood of fat fingering the filename.  Typing ...put factor.bin is a lot easier than ...put downloads\aredn-3.20.3.1-ath79-ubnt_nanostation-m-factory.bin

If all else fails don't trash

If all else fails don't trash it you can use the serial recovery method using the original OS. I have done it but it's a bit complicated.
