The guide was very well put together, I was able to swap out the part, no problems at all. Great job. For those seeking the same resolution I was for my problem: Swapping out the part did not fix my issue. I still receive the same “CardReadError” when inserting any one of my 33 switch games (though, for whatever reason, Monster Hunter works just fine, it’s the only game I own that the switch will read")

I will continue troubleshooting… hopefully get it figured out. If I do, I’ll come back and comment more. If I don’t, this will sadly be the end of the road for Nintendo with me.
