There are at least two types of fixings for the case, one has small screws under the 4 round covers on the edge of the case and the other type dont have the screws, check and remove the screws, using a thin plastic strip (I use a guitar plectrum) slip it between the front glass and the side frame, start next to the on/off switch and work your way round until the front is free. BE CAREFUL of the two ribbon cables that connect the screen to the pcb, only open the two halves at the top of the tablet, keep the bottom together. Once you have it open you will have to remove the three (IIRC) screws that hold the pcb to the rear case. Carefully lift the pcb away, watch out for switches and switch covers catching on the case. Locate the internal tf card, slip it out of its holder and fit a new card. Reassemble in reverse order.
