Problem with BIOS flashing.
Problem with BIOS flashing.
Hello, I see you're working with an MSI X370 Gaming Pro Carbon and trying to update the BIOS on version 2017. The M-Flash isn’t detecting your USB, but it’s unclear which port to connect it to since the user manual doesn’t provide guidance. You may need to check the device manager or consult the official MSI support resources for the correct USB slot.
It doesn't matter which USB port you choose if you're accessing it through the BIOS settings. The exception arises when using BIOS flashback, which this device doesn't support. Two possibilities come to mind: The flash drive might not be formatted properly. It should be formatted with FAT32 for the BIOS to recognize it reliably. The board tends to be strict about flash drives—consider trying another drive and observe if success improves (generally, slower or older drives perform better)
for this particular board, the port choice isn't crucial. it's usually better to connect the rear USB straight to the motherboard to avoid extension problems. the issue might be a faulty USB stick or an improperly prepared BIOS file on the drive. check the instructions again and verify everything is correct. if needed, try using a different USB stick.
