I am trying to update a BIOS on a Dell Inspiron 15R 5520 using a DOS-Based environment. I have downloaded the BIOS update from Dell's support website, which is 5520A14.exe, and have put it on a bootable USB flash drive using the Dell Diagnostic Deployment Package.
When I run 5520A14.exe after I boot the system it just comes back saying 'Test.' and does not run the BIOS update utility. I thought maybe the executable may have been corrupt, so I downloaded it again, and still had the same issue.
I also tried downloading the executable for revision 13, which did the same.
Please advise me on my next course of action.
Installing from within a Windows 8 environment is not an option.
Thanks for the help.
