i broke mine too, left the card in when i opened it, the bay broke. i also broke the magnetic keyboard connector on the tablet ,the day i got the keyboard.
i had a closer look and looks like its hard to repair need to take apart the board to get to the tf card. i just put a black electrical tape so no one can insert an sdcard inside
I think we all made the same mistake–better TAKE OUT MICROSD CARD BEFORE OPENING UP THE TABLET!
But does anyone have tips on how to get the cover back on somewhat easily? I just looked and I think the rear camera is out of position so I may have to risk another re-opening to fix that, and could break something else..oh geez.
