Will changes get lost on firmware upgrade?

Great work clashcityworker…the thing I’d be curious to learn is if there was a manual way to load these bin files onto the Mirror. You’re already way ahead of several others who’ve been trying to solve this puzzle…your further success in researching this will definitely be valuable info for many in the community… See this My Cloud EX4 thread → http://community.wd.com/t5/WD-My-Cloud-EX4/My-Cloud-EX4-SDK-Reality-or-Myth/m-p/758026

I am gonna post a link back to this thread in that thread…there might be others who might be interested about your findings. And though that is EX4 and not the Mirror product, these products vary only slightly in hardware…the firmware code is nearly identical, with only some minor features disabled in Mirror.
