Hi,I just received an Eken m003 last Friday from Ebay. It worked ok, but in the upper left corner, next to the calandar, it say "Demo version only" in red.Now, it says, "DEMO VERSION HAS EXPIRED" accross the whole screen.It had 1.6 firmware on it from the factory...I did NOT install any other apps, I don't even have wife at my house.I tried upgrading the firmware to Ecotox 1.3.1 that I downloaded onto a microsd card. But the message is still there. (the Ecotox 1.3.1 does seem to be better firmware, though...I can see market on there, and it does seem a little faster). But the demo screen seems to be in the hardware.I have a backup of the original 1.6 software, if I need to put that back on to sent it back...but has anyone else had this issue? Any suggestions? Thanks so much!
