Has anyone found a solution for this error for the Nintendo switch? I have tried a replacement Card slot with 3.5mm audio jack but still same results with error when inserting a game card in. Now attempting a full wipe of the device to see if that resolves anything. Any advice other than send to Nintendo will be helpful.
Clean contacts of both connectors and look for broken / bent pins on the mainboard connector
Could you also unplug the microsd board and see if it makes a difference
has the micro sd card slot caused problems in the past with errors?
I tried this and still same results
Error Code: 2002-2663
