Having trouble flashing several bullets

Guys,

I am real green horn, and I have flashed several of the WRT54G's with no problem, but now trying to flash a Ubiquity Bullet V3.5.4494 and a V4.0.3. I am getting an error message when I try to upgrade it of "Bad Firmware Update Image". I am using the Factory upload. I am able to communicate with the Bullet normally and it seems to work, but will not flash. Help!

73,

Have you tried the

Have you tried the instructions on our SOFTWARE page?  ie.

 

BEFORE flashing a Ubiquiti device that is running or has been running airOS version 5.6, please run the AREDN U-Boot Test program below. 

We have developed the following utility to help determine if your device is compatible, as well as being able to take a BACKUP of your critical partitions.  Download and run the AREDN U-Boot Test Setup Program.   If the test results in a "GOOD/GOOD" result, you may proceed to load the appropriate AREDN firmware on it. 

If the test results are "BAD", you should do the following:

  1. Backup your device partitions using the AREDN U-Boot Test program.
  2. Use the AirOS GUI to downgrade to AirOS v5.5.x.
  3. Re-run the AREDN U-Boot Test program and look for a "GOOD/GOOD" test.
  4. If "GOOD/GOOD", you can safely use the AirOS GUI install AREDN firmware.

Requires Windows 7 or higher and Microsoft .NET Framework 4.5.

Also, to confirm, these are Bullet M2's not just a plain "Bullet 2", right?

Thanks! I guess this falls

Thanks! I guess this falls under the heading of a fool and his money will soon be parted. I tak it that the Bullet 2 is not flashable. I will have to look for some M2's!

Tnx for the backup tool.

But how do you restore them?

I have a M2 bullet 60 feet in the air that I have to restore.

I have tftp access  but loading anything.BIN doesn't restore it. UBNT nor AREDN software.

Tnx,

André

Tnx for the backup tool.

some background:

I had success loading latest AREDN software on it. It worked for 2 days then nada.

It was running UBNT 5.5.8 before and I did backup the partition.

Any restore tool?

You'll need TFTP the original

You'll need TFTP the original firmware back onto it (probably to 5.6.*), then re-downgrade the firmware to 5.5.*, then install the AREDN firmware. Ubiquiti has a pretty good knowledge base article and video on it: https://help.ubnt.com/hc/en-us/articles/204911324-airMAX-How-to-reset-your-device-with-TFTP-firmware-recovery
