DIY Update from 74.00.312 4A N to 74.00.324A 4A N - Invalid SD Card

[sumdayMiata]

Not sure where to go from here. I've followed the steps exactly but when I plug in the SD card to the car, it keeps saying invalid SD card. 2022 Mazda CX-5

Tried different SD card adapter
Tried new SD cards
Formatted to MBR+FAT32
Copied .up file
Plugged it in, invalid SD card.

What else am I missing?

Perhaps just buy a new SD Map off the internet. Yours has become corrupted.

I am not trying to update the maps…This is the firmware.

I've been trying to flash it using the sd card slot. The instructions say USB. I’m too tired…

I've never heard of using the SD card for updating Connect. USB only
