How to solve obdstar X300M “Load Data Error”

Ordered OBDSTAR X300M and when I plug it to one 2012 Ford Escape and one 2009 Dodge Caravan, I got “Load Data Error” message (shown as below).


After giving the serial number to obdstar, I got the solution. The X300M was already registered, what I can do next is:

Format the memory card first, then update again.

If not succeed by formatting the card and update, maybe there is something wrong with the TF card, please take it out and replace one new (buy one in your local shop), the method is: format this new TF card first and then to update.
