I did my other nodes (two Airrouters, and two M900's) and only the Airrouters were a bit reluctant to do the upgrade (had to do them twice). But I have a Bullet M2 titanium that just won't do it. It keeps booting back to the old version, 3.20.3.0 Doing it over their LANs hard wired. Must have tried it about 5 times, no dice.
Maybe I'm using the wrong file aredn-3.20.3.1-ar71xx-ubnt-bullet-m-sysupgrade.bin
WTF.....
Then ssh to the node and run sysupgrade -n on the file. If it fails, it'll tell you a bit more about why.

I tried SCP and ssh, got:
root@WA2ISE-QTH:~# sysupgrade -n aredn-3.20.3.1-ar71xx-ubnt-bullet-m-sysupg
rade.bin
Image metadata not found
Use sysupgrade -F to override this check when downgrading or flashing to ve
ndor firmware
Image check failed.
I'll try dpwnloading the file again, maybe it got corrupted?
Did this, same result. Do I risk sysupgrade -F to override this check?
If you can do an md5sum on the binary file, it should be 5312852b64de0c6ef5de61d271692878
I got it to do it, but I used the FW listed for the titanium bullet XM, with md5sum: c7779834840a58491d65e231d752f473
And it looks to be working normally.
I suspected I might brick it if I did the -F
