Chosen Solution

i haven’t touched my 2ds in about a year and i wanted to play it, but it wont read my cartridges except for two (I’ve looked at the back of the cartridges and they look the same). i put it in an older model and the games read without issue. taking the device apart inst really an option for me, is there any other way i can fix it?

Back in the day when I had a 2DS and this used to happen, I would blow in to the game card slot.
