USB Not Detected after firmware update

Encrypted32

2014 Mazda 3 Active
Heya


I'm in the process of upgrading my multimedia & hardware to support AA on my 2014 Mazda 3
I upgraded from 29.xx, to 31.xx, to 56.xx, to 70.xx but after updating to 70, the car no longer detects any USB (trying to upgrade to 74.x)

Did a full reset (battery disconnect for 20min), formatted the USBs multiple times on fat32, multiple USB sizes & brands (anywhere from 64gb all the way to 8gb), any possible solution I could find on the internet didn't work

The only thing I found in the diagnostic menu that might be related is this following error when doing Diagnostic code 3: "CMU DTC 1 - B125287 (USB Port 1 -Missing Message)"

Plugging in my phone gives it charge, and for some odd reason a message keeps popping up that android auto is connected (I didn't install the hardware yet, and I have turned off auto AA setup on my phone)


Has anyone ever had this happen to them? I'm very lost right now.

I am currently on version 70.00.100A EU
