Newbie here

I just got a second hand kobo aura h20
It is frozen and displays 5 square icons in the middle.
Tried all forms of reset and still doesnt work
Opened up the inside and found that the inner SD card was gone.
Is it possible to buy another SD card and install the image file?
Will that make it work?
If so, is it possible to send me one?
Thank you very much for reading and anything really helps!
