Why can't the Vita detect my memory card after taking it apart?

This was my first time taking apart my PS Vita to replace a left analog stick that became faulty. I took out the game cartridge, but not the memory card before I took my Vita apart. Once I finished replacing the analog stick I turned on the Vita only to find out that it cannot recognize the memory card.

I tried restoring, restarting, and rebuilding, but the memory card could not be read no matter what I did. I was unable to format the memory card in safe mode since I kept getting errorc2-13209-5. I have not tried another memory card yet as this happened at an unexpected time.

I was following the instructions on ifixit and now I wish there was some kind of warning to take all cards out.

A solution to try is inserting the memory card to your PlayStation TV, if you own one. I don't know if this is guaranteed to work for anyone else but it did for me and worth a shot.
