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?
