Hey there - running up and down the net using Google and all other known possibilities I ended up opening a nu thread for this issue.

It is related to the MB-model - Z270M Pro4

I run it with the BIOS version P1.4 and want to update to the latest one P2.50.

Since hours I try to update it by different strategies using different USB drives/stick with FAT32
Setting the BIOS to default, restarting and retrying it.
Trying different USB ports (2.0/3.0)
Trying to update first to P2.00 - did not work - same result: "secure flash failed"

I have no modded BIOS! This is outside my capabilities - I´m an casual user trying to keep his system components up to date.

Can you tell me how to manage this?
