Bricked APX 320?


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!

  • That worked - both devices are now logging to the serial ports and I can read them.  They're stuck in a boot loop due not not findinng a kernel, they boot cycle can't be interrupted by pressing a key, and flashing doesn't work on either device, although the TFTP process does at least start on one device.

    I think it's time to initiate the return.  I provided the seller this link, so I suspect he's satisfied with my diligence.

    Thanks to you and everyone who assisted - it's greatly appreciated!

  • Hi,

    i was able to interrupt the uboot process by changing the autoboot delay to 5s by changing the GD25Q32 content ..
    Just search for bootdelay and change 0 to 5 ... and flash back.
