Bricked APX 320?

Hello,

I recently purchased two pre-owned 320 APX APs for my home. Both APs boot into solid green, fast flash red, change to solid green, and then flash fast red again. They never become visible in UTM 9 and appear to be bricked. I've left them connected for hours, and this cycle never ends. Resetting has no affect, nor does rebooting during the solid green phase (I didn't boot in flashing red, as supposedly that's a firmware upgrade in progress).

Two questions, if anyone knows:

1) Is this what happens when they're bricked?

2) Where can I download the APX 320 firmware? I'd like to give the flashing tool a go.

Thanks in advance for anyone's assistance!

Jim

Link to Recover a bricked Sophos AP

It looks like the firmware is already included in the download tool.

Hey, Alan. Not sure what you mean by included in the download tool - could you please explain?

Thx!

The Sophos Flashing Tool opens a TFTP port on the computer to serve the firmware file to the access point.

This would make it seem as if the Sophos tool detects which APX you have and has the firmware for it.

I would make sure sure you follow the steps EXACTLY to do the full reset first by holding the reset button until the LED is solid red, then blinking red, then release the reset button.

I came across this tutorial where they say to use a usb-to-RJ45 cable and connect to the AP using putty.

That's not the behavior I get. If I pull the power and push it back in, I get a brief amber, then green. If I hold the reset button while still green, I get a slow blinking red for about 10 secs, and then a fast blinking red. I never get a solid red.

Both of the (new to me) devices behave the same.

IMHO, the reset doesn't reset.
