Hi
This may be quite hard but we will get there!
The first thing I would try is get some fine tip tweezers and try and pull what’s left of it while inflicting minimal damage
You could replace the SD car reader but that requires soldering but it’s not something we want to do
As a last resort you could try a small amount of super glue to clue the card back together so you might be able to get it out but we leave that as a last resort as if too much glue is applied it could get stuck
Hopefully this helps
Any questions please ask
Thanks:-)
