Nintendo Switch card reader error

So my Switch Lite isn’t reading games. I replaced the card reader, factory reset the device and have the most recent update and it still won’t work. Can someone point me in the next direction? I want to do everything at home. I bought the switch broken. Like inoperable. And now the only issue is the card reader. I’m willing to sacrifice it in the name of higher learning. So tell me what I need to do next.

In most cases it is the entire reader that is damaged, replace it and it should work correctly if the connector is fine if it has no pin damage it is the complete reader good luck

I replaced the reader already. Still the same thing

I already checked the flex connector, it could be that the pins have been desoldered, this could be your case.

I’ll check as soon as I get home
