ST is G1SPN42...

Hello,

I am looking for any bios for Dell AIO 3480. I don't know how, but Windows Update made bios upgrade to version 1.17.5. It is newer than available on support website

I have tried to downgrade with FAT32 usb disk but I get error that bios downgrade is NOT possible. I cannot change option in the BIOS.

What is very strange - this looks like 'old' BIOS, not standard graphical BIOS/uefi with windows and possibility to usemouse.

I am affraid if there will be any other method than putting it through CH341 programmer?

ANy help is more...
