UBNT-SNK on their forum suggested the following:

> 1. We have seen a number of older XM devices (typically 3+ years old) being affected by a crash when running the airOS v6.0.6 firmware. The timing and frequency of the crash varies but from what we have seen, it is limited to those older XM devices.

There is a path that allows you to do this remotely: load the airOS v6.0.6 beta firmware on a device running airOS v6.0.6, and from there you are able to downgrade back to airOS v6.0.4 or an earlier version remotely.
