Can't disassemble Innioasis Y1

My Innioasis Y1 failed on me two days ago (i assume it was the SD card) and I've been trying to disassemble it, however I've yet been able to do so. Does anyone here have any tips on how to do it? I tried using cards and a finger nail, to no avail. I have a prying tool somewhere in my room, I just can't for the life of me find it anywhere.
