Hello,

I have a Dell Precision 5510 on Linux.

My BIOS was in 1.4 and computer work fine. Since I update my BIOS to the last version 1.14.2 I have some problems:
- At start I have  this message: "(A7) Me FW Downgrade - Request MeSpiLock Failed" (but computer can start).

- After lid closed when I reopen I have this message: "Boot Guard verfied DXE that is fail", so I need to reboot

So I try to downgrade BIOS to 1.4 but I have this screen, so I cannot select the file to downgrade:

Thank for your help
