Rosewill RD-162 firmware & Aopen 1608 ARR Question

Rosewill has only made firmware for their drive available up to a080, while Aopen has made version a110 available. Anyone have any tricks up their sleeves for making that drive accept the 110? I’ve only sent about 3 messages to Rosewill asking them to and their reply is always something along the lines of “We’re on it.” … right. Anyone?
