Latitude 5480 will not update BIOS
I have a Latitude 5480 with a clean install of Windows 10 Pro. The BIOS will not update to the latest version, the BIOS is currently 2 versions behind. I've tried to update via running the BIOS exe within Windows, using the Dell Command Update application within Windows and via USB at boot time. There's no failure warning or prompts the laptop just reboots normally into Windows 10 without going through the usual BIOS install routine at reboot.
I've tried resetting the BIOS to factory default, disabling Intel Virtualization, disabling secure boot, temporarily changing to Legacy boot mode, trying to install just one BIOS version ahead, and disabling Fast Startup in Windows.
I'm kind of at a loss, would anyone happen to have any ideas?
Thanks in advance.

You might check and make certain that Bitlocker is disabled when downloading the BIOS file to your computer. Bitlocker can interfere with BIOS installation.
