Odd problem installing on NanoBridge M5

I have run across some NanoBridge M5 units that I can't install the firmware on. I can't install any version, recent or old. These have AirOS v6.2.0 (XM), when I do the tftp transfer, it almost completes and then I get the error "Firmware Check Failed". I'm just having this problem with these 4 nodes, I have no problem with others. Are there some unusual ones out there that have this problem?

August,   This has occurred

August,   This has occurred before and I received one to look at, which I still have (but not with me at my other QTH).    I was able to load an image on the device, so we never got to the bottom of the issue.   ...and I need to see whose callsign label I put on the device to remember who sent it to me :) .    I'm not sure if I held my hand just right when hitting the return key or did something a little different to load the image, it's been several months.

The issue hasn't popped up

The issue hasn't popped up recently and no further activity on this issue has occurred that I'm aware of.   

Note, it is very important when changing from one version of AirOS to another version, to load the new firmware from the AirOS UI.  This is the only path that will upgrade/downgrade the bootloader.   loading AirOS with tftp process does not change the bootloader version.     If a newer version of AirOS has an upgraded bootloader in the image, and the firmware is loaded in the AirOS UI, then the bootloader code is updated on the device.   If there happened to be a conflict with OpenWRT or AREDN, then to roll back and downgrade the bootloader can only be done by downgrading AirOS from AirOS to get back to the desired older bootloader version.

what aredn firmware is the known to work on a nanobridge M5 XM

I am not seeing that exact model in the Stable or Nightly Build Firmware Readme.
I see a NanoBridge 5G22/5G25.
The 'NanoBridge M' is in the openwrt table of hardware (v19.07.6).

You did not mention which .bin you were using.
Was it aredn-3.20.3.1-ar71xx-ubnt-bullet-m-factory.bin
or
aredn-84-99305c5-ar71xx-ubnt-bullet-m-factory.bin ?
