I've recently purchased an IRobot 7 inch tab from ebay. The MID user manual says it is an EM73 - Telechip 8803, 1.2MHZ, 512MB DDR3, 4GB NAND flash. I got myself an SD card and put it in the SD slot, it didn't feel right so i flipped it over and put it back in, again didn't feel right so thought a little extra push would do the job... silly me, it is now stuck as i think i missed the internal slot and is now sitting just above the slot. I think i need to remove the back to get to the SD card but i'm not sure how to get the back off. There are so many different types of tabs and haven't seen anything that shows how you remove the back to this one. I've seen ones that have screws at the back or you rip the front screen off to reveal the screws but i think this one there isn't any screws but you need to work the back off. However before i try has anyone been successful in removing the back of one of these and if so how did you do it?
