A few weeks ago i purchased the Dingoo which worked like a charm.  1 week ago i noticed that my internal memory was nearly filled.  So I went on to amazon.com and purchased a Kingston 8gb Micro with an adapter set.  (http://www.amazon.com/dp/B0028R2I5S/ref=asc_df_B0028R2I5S1025292?smid=ATVPDKIKX0DER&tag=googlecom09c9-20&linkCode=asn&creative=380341&creativeASIN=B0028R2I5S)  When it arrived i opened it and plugged the microSD chip into the Mini adapter then plugged it into the Dingoo.  The second the card goes it the Dingoo screen goes black.  I pulled the card out and the Dingoo wouldn't turn back on and only turned on when the reset switch was pressed.  I then turned to this site looking for possible answers.  I tried pushing the card in slowly but that didn't work.  Made sure the MicroSD card was in the adapter tightly.  I laid the Dingoo on a flat surface and tried to push the card in accurately but that didnt work.  I do not know what to do with it.  If you have any suggestions please leave a comment or email me at Blighted_mind@yahoo.com.  

PS.  My Dingoo is v1.2(came with the Dingoo)
