I have the same issue as this thread: https://www.arednmesh.org/content/untested-hardware-nanostation-m2-and-32030
I'm using two identical units. Both were flashed with aredn a few years back and were working as recently as last week. Decided to upgrade to latest version. First one went off without a problem. Used sysupgrade and upgraded to 3.22.1 (aredn-3.22.1.0-ath79-generic-ubnt_nanostation-m-squashfs-sysupgrade). It works fine.
When I did the second one, the RF did not come back on and I knew there was an issue. I finally found it at 192.168.1.1 with the "untested hardware" banner. Here is the support dump:

I eventually used TFTP to take it back to aredn-3.19.3.0-ubnt-nano-m-factory.bin and it recognized the board and worked as expected. However, if I tried to upgrade via sysupgrade it produced the same issue (board unrecognized).
