First Node Attempt

Hi everyone, first post to this forum.  

I bought a NanoStation loco M2 recently and started through the procedure to turn it into a node.  It showed up in AirOS as having Version v5.6.2 (XM) firmware - so far so good.  When I next ran the AREDN U-Boot Tester, it gave me a BAD/GOOD result.  OK, off to www.ubnt.com/download/airmax-m/nanostationm/locom2 to look for older firmware.  The problem is that all of the choices that it offers (v5.6.5, v5.6.6, v5.6.7, snf v5.6.8) are newer than what is presently on the loco M2.

Does anyone know of a source of 5.5.x firmware?

Thanks in advance,
