I’m trying to update the firmware on my 2014 Mazda 3. It was on version 28.00.100, so I first went to update to 31.00.100A like I read online. I did the failsafe update, but now I keep getting an error message during the install.
I switched to a smaller and older USB drive since that’s often suggested, but the error doesn’t go away and it won’t retry the installation. I checked the files, and the hashes seem to match. I’m also sure I’m using the correct region.

Try using a USB 2.0 drive. I’m pretty sure USB 3.0 won’t work unless you have the USB 3.0 hub, which requires v70+ firmware to install first.
This actually worked, thank you so much! I found a 64GB USB 2.0 drive, reformatted it to 4GB, and it seems to be working now.

Did you get the detailed instructions for doing the update? I’ve done this three times using a USB 3.0 drive without any issues. While USB 2.0 is recommended, I don’t think it’s mandatory.

Yeah, I had the detailed instructions. USB 3.0 just didn’t work for me. Maybe your car has hardware that supports it, and mine doesn’t.
