No SD CArd after install picofly OLED

[LuigiGad]

After I finish mounting the Picofly on the OLED successfully, I do an OFW boot test to verify. Everything is ok, I put everything back on and when I turn it back on I notice that the microSD is no longer recognized. Having other spare parts I do some cross-tests realizing that the card that has cartridge reader and micro SD reader has the latter no longer working. I replaced the card for the return to the customer. The card is perfectly intact what can I check to attempt a recovery?

I would start by checking the pins in the connector that connects to the mainboard.

You might want to consider just buying a new one though, it's $20 on aliexpress
