I dropped my 2DS XL and cracked the top screen pretty bad. Can I replace it myself?
robert Boyd, yes you can. Check the teardown on here Nintendo 2DS XL Teardown Also not a guide, it will give you an idea of how to get there.
go to the service centre and ask if they could fix it.
It is pretty hard to replace the screen so you might want to try to get a whole display replacement if it’s the top screen if you can’t afford it just take it to a professional who specializes in fixing the Nintendo 2ds
