Hacking SuperCardDSTWO not recognized

[taleoson]

I have had my Flash Cart for 4 months and it has stopped working. I have tried the paper trick and it stopped working, tried making the paper thicker. Then I tried duck-tape and it worked for a little bit but then crashed, peeled off the tape and the sticker came off . I took out the screw on the back to see if I could fix the pins and lost the screw. If I find it is there anyway to fix this. Please I do not want to have to replace this
