I want to purchase another ASIAIR and reset the Firmware to a ver of 1.9.2 or earlier. I then plan to update with 1.92. My concern is that resetting a new purchase will install a version of the firmware later than 1.9.2 thereby preventing 1.9.2 loading. My reason for this is 1.9.2 is performing flawlessly for me and I am no running into the issues users of new firmware are having. I would prefer to purchase a new unit and not older used one.
