I have a micro SD that is lodged inside the tablet I can hear it rattling around inside . Some how I tried to insert a micro SD and pushed it all the way in, I though a little nudge is all it needed, maybe it was the wrong size. How do I take the back off this tablet to get the micro sd card out. It is a unbranded 9.7" Wonder media 8650 MID tablet. I read people buying tablet repair tools off Ebay is this any good to do it myself. I don't really want to go to a mobile phone or computer shop just to do this. Any ideas how to do this.
