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?

I am seeing the same thing on some nanobridge M5s I tired going back to a v5.6.15 firmware, and up to 6.3.2 but I get the error when trying to tftp arden 3.20.3.1 bullet, did you ever find a fix?
thank you
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.

would you be able to verify what aredn firmware is the known to work on a nanobridge M5 XM build number 33267
i just entered this post and shocked by the history here.

My question was, I need recommendations for the correct firmware ???
Device Model: NanoBridge M5
Network Mode: Bridge
Wireless Mode: Station
Version: v6.1.7 (XM)
I see that openwrt now has support in ath79 architecture and current builds. This will make it easy to adopt.

Right now, the ar71xx bullet-m images are the safe ones to use. The ath79 bullet images originally never had any testing to know if any issues.
There are probably at least a hundred of these devices in use with AREDN firmware. There must be something isolated and unexplained or numerous groups would be chiming in.
