No, I have this unit under 2 weeks. When it came the registration code for the tablet was stamped on a label on the back of the unit. I put in the reg code and now it seems that the latest update requires you to put the reg code in. Well I don't know what sort of ink they used for their stamp but when I looked at the label the code is erased probably due to me handling it. So the image of the reg code that I have already put in must be on the internal memory somewhere.
